Small gas steam boiler best suited to the laundry room with the rapid economic development, also in the laundry industry in various regions of the world to do fast, like LDK, UCC have made the international brand. Expand the size of the laundry industry, can not be separated steam boiler, steam boiler small gas today small to say it is more suitable for laundry. Generally, 0.5 tons of steam produced by the boiler steam biomass per hour 500kg, drying clothes can be used between 300 standard. 1 ton of steam produced by the boiler steam biomass per hour 1000kg, 700 can be used for drying clothing standard room. 2 tons of steam produced by the boiler steam biomass per hour 2000kg, can be used for drying clothing between 1500 standard. So basically very large laundry room with a small steam boiler to meet. WNS type of fuel gas-fired boiler (Horizontal internal combustion chamber fuel gas-fired boiler) is specifically for this mini-laundry and students, it is the development of technical cooperation with the German boiler products, both to fuel gas can, the technical indicators reached the world advanced level, the implementation of sub-projects of the World Bank is one of GEF boiler efficient and environmentally friendly projects. The more types of boiler combustion machine to join an internationally renowned, really do clean burning, emissions of pollution-free, easy operation, ample output. As for the price of small gas boiler, in this small series is no way for you to determine the offer, which requires a combination of boilers and auxiliary equipment specifications laundry at home who they need and so on. If you need detailed quote and boiler configuration program can contact and small series, small series will be combined with your situation to give you the most appropriate answer. We just want to know there is a boiler operating costs, including fuel costs, maintenance costs, electricity, labor fees. And most of the operating costs are fuel costs, small gas boiler and gas consumption is 78m3 / h / t. The total operating costs also need to combine their laundry home to their own circumstances budget.
The main reason gas steam boiler produces smoke which fuel gas steam boiler main cause of smoke. A fuel gas steam boiler: oil, gas oil quality is not good when the gas contains more water, reduce the heat value of the fuel, while producing steam, the furnace temperature tends to decrease, making it difficult to burn, easy to produce smoke. Water and more oil, mainly when unloading rain water into the oil during heating the oil in water vapor penetration. When the oil contains impurities, the impurities unburned produce fine coke, the coke into fine smoke, dust becomes large, and the formation of soot. Impurities contained in the oil and gas, but also affect the pure oil and pure combustion gas generated soot. Oil impurities, mainly due to inappropriate choice of filters or filter difference impurity removal effect. Second, the failure of the fuel atomizing nozzle member main burner fuel oil atomizing nozzle. Atomizing oil burner nozzle fails, affecting the quality of the atomization, easy to poor combustion. 1, the adhesiveness between the bonding surface of the oil and the consequences of failure oil atomizers swirl atomizers and the splitter plate well, leakage will occur, atomized large oil particles, increasing the amount of fuel injection and the like. In this case serious deterioration of the quality of the combustion, the oil droplets have landed on the water wall, stacking up oil coke, partially unburned black smoke into droplets. The tangential swirl chip groove clogging mist causes uneven density distribution in the dense side of the oil mist, combustion air be insufficient. In the more dilute side of the oil mist, combustion air causes severe local excess. Mixed with oil, wind conditions deteriorated significantly, combustion conditions deteriorate, resulting in black smoke. 2, spray atomization slice failure and the consequences of failure to clogging and wear. Nozzle clogging, resulting in blockage of the fuel injection quantity is not glib increase, oil particle size thicker, the effect of fuel poor and black smoke. Wear injection port, a large hole diameter, increasing the amount of fuel injection, increasing the particle size of oil affect combustion efficiency, produce black smoke. The use of artificial gas burner, naphthalene and tar and other impurities will block the nozzles, the influence of gas distribution, resulting in black smoke. Should therefore be cleaned regularly, or clogging of the selected burner. 3, the partition partitioning poor poor, insufficient supply of air into and excess. The amount of air can not meet the requirements of the fuel combustion, so that combustion of fuel can not be sufficiently black smoke. The amount of air, will result in lower combustion temperature, black smoke and fuel difficult to burn. 4, the furnace temperature is too low when starting the furnace, fuel oil steam boiler furnace temperature is too low due to easy black smoke. 5, the furnace hearth product oil is sometimes caused by internal combustion nozzle oil accumulated inside the chamber, the oil reservoir coke black smoke at high temperature. Causes dripping of fuel combustion nozzle: ① The drip just work, just at the operating pressure is too low, the oil will flow from the nozzle, instead of the discharge. The reason for low oil pressure is a solenoid valve, the valve is clogged filter or the like or failure caused by contamination. ② In the dripping process work, probably because the relative position of burner nozzle mounting head too far, improper ignition electrode position, the oil into the atomizer, the nozzle holder is mounted is not tight, nozzle dirty, low oil pressure caused. ③ When the dripping stopped, because the line between the pump and the air nozzle, electromagnetic valve or a hydraulic valve or dirty failure. 6, the furnace flue purged countless consequences when the furnace flue remnants of oil and gas, when gas purging endless, high temperatures encountered in the explosion and black smoke. 7, the furnace smoke, sparks, the furnace pressure is too ①; ② inappropriate choice of the burner, the burner flame is too long or too much power; ③ improper combustion ratio, there are more to produce products of incomplete combustion; ④ atomization quality is not good nozzle or improper installation location, or affect the combustion flame into the furnace off port; ⑤ flue is blocked, poor smoke; ⑥ a secondary air mismatches; irrational ⑦ furnace structure; ⑧ oil spray angle is selected from with improper.
Recently, the National Energy Board, the Department of Ecology Environment issued "on the issuance of 2018, the provinces (autonomous regions and municipalities) of coal ultra-low emissions and energy-saving targets and tasks" (the "Notice"), called on all localities continued to do over coal low-emission and energy-saving, and promote the development of clean and efficient coal. Ultra-low emissions and to promote energy-saving work in the country has been more than two years, has been established to complete the task of transformation in the eastern provinces, the transformation of the focus shifted to the central and western regions, while the transformation of scope as technology advances and the increasing demand for policy gradually extended.
Under the "notice" requirement, this year nationwide, ultra-low emissions coal power reform objectives and tasks a total of 48.68 million kilowatts, energy-saving goal is to reach 53.905 million kilowatts. In 2016, the capacity of the units involved in the transformation of two to 254.36 million kilowatts, respectively, and 189.4 million kilowatts, good reform bear fruit.
President of the State Power Environmental Protection Research Institute Zhu France and China, said: "By the end of last year, a nationwide ultra-low emissions transformation target task completion rate has reached 71%," ultra-low emissions coal and transformation better, the eastern region has been basically completed, part central provinces ahead of the completion of the task of transformation.
In 2015, the former Ministry of Environmental Protection, the National Development and Reform Commission, the National Energy Board issued "the full implementation of ultra-low emissions and energy-saving programs of work-fired power plant", requires the completion of the eastern part of the overall transformation of ultra-low emissions before the end of 2017, the central region and strive in 2018 years basically completed, the completion of the western region in 2020. "2018 provinces (autonomous regions and municipalities) of coal ultra-low emissions and energy-saving task summary table" (hereinafter referred to as "transformation task list") shows that the eastern provinces have been basically completed the transformation of ultra-low emissions, not published this year transformation capacity unit task. But it is located in the Yangtze River Delta, Jiangsu Province, still issued 1.4 million kilowatts ultra-low emissions and energy-saving renovation target of 900,000 kilowatts.
Zhu France and China, said, "in accordance with the requirements of 2015, Jiangsu has completed the ultra-low emissions and energy-saving target in 2017. However, the new policy will be more units into the transformation range, Jiangsu this year, there is still the task of transformation. In June, the State Council issued a "winning blue sky battle three-year action plan" (hereinafter referred to as "three-year action plan"), required by the end of 2020, more than 65 tons of steam key areas of coal-fired boilers have completed ultra-low emissions and energy-saving. "
It is understood that "three-year action plan" prior to the implementation of energy-saving and environmental protection requirements only for the reconstruction of more than 300,000 kilowatts of conventional units, more than 100,000 kilowatts of power plant owned units. "According to the existing requirements, including Beijing and Tianjin and the surrounding areas, the Yangtze River Delta region and Fenwei plains, including the key areas, more than 65 tons of steam boilers are also included in the scope of the transformation will involve part of 100,000 kilowatts or less captive power plant units and industrial boilers. "Zhu France and China, said," "three-year action plan" in addition to the deadline of 2020, does not provide a specific timetable for the task. Next, the key areas are the provinces in accordance with the requirements of more units, boiler transformation. "
"Task of transformation" table displays, ultra-low emissions transformation capacity this year, mainly in the western region of Inner Mongolia, Shaanxi, Gansu, Xinjiang and so on. In the trend of ultra-low emissions overall speed of the transformation, central Shanxi, Anhui, Henan and other provinces in the region have been completed ahead of the transformation target ultra-low emissions, but energy-saving task still more arduous. Among them, Henan Province this year, energy-saving target capacity of 10.8 million kilowatts, Hunan has reached 9.995 million kilowatts.
Since the ultra-low emission transformation involves the emission of pollutants and other environmental problems, caused by the high social concern. In contrast, concern about energy-saving electric power mainly from the enterprises themselves. Zhu France and China, told reporters, on the one hand is the national energy saving policy requirements, on the other hand also in line with the needs of enterprises to reduce their own costs. At present coal prices continued to run high, coal companies operating pressure, reduce production costs even more urgent demand.
In 2014, the National Development and Reform Commission, the former Ministry of Environmental Protection, the National Energy Board issued "coal upgrading and transformation of energy saving action plan (2014-2020 years)", for energy-saving technology roadmap active coal-fired power units were enumerated, involving the master each link auxiliary equipment, environmental protection equipment and a total of 20 reform measures, in addition to "subcritical unit transformed into ultra (ultra) supercritical units", the rest of the technology have already matured.
In recent years, along with tighter environmental requirements, provide renovation and operation and maintenance services to the rapid development of environmental protection industry. In particular third-party environmental companies, with technical, cost and other advantages, occupy a certain share of power generation enterprise environmental transformation market. But a power industry experts said, is very difficult third-party independent companies to enter the field of environmental protection energy-saving power plant.
"Ultra-low emission increase in the transformation of the original system is new equipment, energy-saving and optimized for major transformation of existing equipment, and boiler plant, steam turbine plant than environmental protection enterprises to understand their own devices." The expert said, "Not only that as systems engineering, energy-efficient coal-fired units involved in the whole process of production, and plant operation economy, is closely related to security, not easily open to third-party companies. third-party companies to enter the energy-saving environmental protection than to enter the market face greater pressure."
Operation of the boiler, including what? Including the operation of the boiler, what does? Following on from the Henan fast boiler company to tell you about: 1. The water level regulation of normal water level in the middle of the gauge (1) of the boiler. Operation with the magnitude of the load is adjusted: to maintain a high level during low load, high load to maintain a low level. Changes should not be down more than 40 mm. (2) to be run on the water level gauge to compare the two groups, if the water level display should be corrected promptly identify the cause. (3) To achieve a balanced continuous boiler feed water, ground water supply, water supply less, to maintain the water level in the normal water level fluctuates slightly in the vicinity. (4) load change is large, prone to false level. Pay attention to judgment, in order to avoid misuse. 2. Steam pressure regulator (1) when the boiler must constantly monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. (2) increasing the boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. (3) boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and to adjust the amount of water. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes. 3. Combustion adjustment (1) combustion index. Normal combustion boiler comprises a uniform supply of the fuel, reasonable ventilation, adjusting three basic aspects combustion. B. maintain a high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100-1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. C. fuel ash to reduce ash content in the combustibles to be below 10%. d. reducing the temperature of the exhaust gas boiler exhaust gas temperature should be controlled below 200 ℃. e. excess air negative pressure holding furnace boiler 1.2-1.4, by adjusting the balance of the blowers to maintain the furnace pressure is 2-3mm. F. to improve the thermal efficiency of the boiler thermal efficiency of the boiler should be kept above 60%. (2) adjusting the combustion a. Reasonable amount and the distribution of fuel to the amount of air needed for combustion. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. b wind principle feature: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. c is the normal combustion conditions: fuel ignition start at 300mm from the shutter of coal, even flames, the fire bed formation, at the end away from the combustion grate at the end of 300-500mm. d. Hold appropriate furnace temperature to avoid coking. E. fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. F. less than 30 minutes residence time of the fuel on the grate. Our company provides services related to the installation of the boiler!Free Chat
