Parameters and heating in winter precautions oil-fired hot water heat boiler oil-fired boiler should set this kind of boiler, I believe we will not feel strange, because the site has its relevant articles to allow them to learn and understand this kind of boiler, and at the same time, also to know the proper use and rational use of this kind of boiler, in turn, have a good economic benefits in the economic performance of the boiler. So, based on this, then, will continue to carry out this work, the study follows. Adjustments and adjust the size of the working pressure 1. conversion or oil-fired boiler control debugging: Under normal circumstances, turn a small fire is 0.9MPa, 0.8MPa turn the fire. Automatic startup and shutdown start furnace: when the operating pressure required is 0.8-1MPa, is adjusted to 1.02MPa shutdown, 0.82NPa start furnace. Overpressure alarm: it is generally set pressure than normal shutdown automatically comparing 0.05MPa. High level alarm: Usually when the setting is the distance of the upper glass sheet is less than 25mm, water enters the alert state. Extreme low water level shutdown: Boilers different manufacturers, it will be different on the set, however, the general principle is that each water tube boilers can not fall below the nozzle. Pump automatic start-stop control: water table is generally set in the center of the vertical and horizontal 25mm. The fuel pressure setting: heavy oil is 1.8-2.2MPa, light oil is 1.6-1.8MPa. Fuel temperature set: If the light oil is not heated, if a heavy oil, will have to control the heating. In addition, daily tank temperature of 60 to 80 degrees, the burner temperature is controlled within the range of 95 ℃ -110 ℃. Exhaust Temperature: oil-fired boiler exhaust gas temperature is 220 ℃ -240 ℃, Super Smoke alarm temperature is set to about 280 ℃. 2. The oil-fired boiler which signals and parameters should be set to indicate? Oil-fired boiler, and a parameter indicative of the signal which should be set for the oil flow into the oil feed pressure, chamber temperature, chamber pressure, the boiler water level alarm limit values and the like which, in addition, there may be some other parameters. Moreover, these terms of oil-fired boiler, is an important parameter, therefore, not be taken lightly. 3. The oil-fired boiler in winter precautions when heating oil-fired boilers, which on heating in winter, there are some precautions, which are as follows: the boiler room should take into account the possibility of development and expansion, between its subsidiary in position, should It does not interfere with the development of the boiler room. If the boiler room is in the factory, living area, it is generally a closed, but in their dust and the wind section, you can open layout.
Food is food industry is human life industry, but also an ancient and eternal evergreen industry. Industrial steam hot water heat boiler as an integral part of the chain, is mainly used for processing of distillation, extraction, sterilizing, drying, curing and other processes. Anqing City, Anhui Province is located in the Want Want Foods Co., Ltd. mainly engaged in all kinds of puffed food processing and manufacturing and sale of steam boiler steam delivered directly or indirectly in contact with food, thus requiring the steam quality is very high. Due to expanding production needs, Want Want Foods in urgent need of a boiler plant to provide high-quality steam. After a comprehensive understanding of the boiler industry, determined to cooperate with the fast boiler. Want fast square perennial cooperation with the country's food company, it has considerable experience of cooperation. By understanding the needs of the Want Want food production, providing a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
The main problems of autonomous decentralized hot water heat boiler heating mode: 1, "two small" boiler room that is small-scale (10,000 m- for the following boilers 60%), small boiler capacity (single boiler average capacity of only 2 tons / hour). "Two low", i.e. the boiler load is low, the thermal efficiency is low. Calculated heat index 70W / m =, 0.7KW (i.e. 1t / n) for 10000m =, in fact, only for 4000m =, less than half, in the "Mara car" low load operation. Thermal efficiency is naturally low, generally only reach 50-60% oC "two can" That is more than the energy consumption, the existing multi-intermittent heating (burning six hours every day and night, stopping six hours, repeated twice). In the current institutional heating intermittent heating accounted for 82%, only 18% of continuous heating. 2, boiler room hire older workers and the burning of a modern boiler during operation merely by virtue of the experience "the sky light a fire," there is no scientific basis for heating, that is, how many points you cold, warm day less burning point, which is very difficult to achieve the purpose of heating and energy requirements. 3, the heating system is unreasonable, due to some historical reasons causing heating in the system has inherent missing, and in the intermittent heating is due to habits die hard so the resulting decline in the quality of heating also a waste of energy. 4, which is related to the owners and the quality of that set out secretly put a hot water tank, can lead to heat loss, water loss occurs, really makes the heating unit is really a headache, which cause heating problems. 5, since the local heating technology of high and low level, so that in the heating process, the heating requirements for the simple pursuit of the distal end of the owner excessively coal temperature of the heating water, resulting in overheating proximal end, a distal end of the warm unbalance, or warm proximal distal cold conditions, which resulted in a waste of energy, will not help solve the problem. 6, the boiler disrepair, will take place at the junction of the pipeline corrosion, fouling and even the phenomenon is really due to the HVAC heating during water treatment errors caused by, resulting in fouling of the boiler heating surface, or Since the agent is such that the boiler ash surface to form grime, which is management problems. 7, the high heat load design makes enormous waste in financial resources, but also makes the device parameter selection is also too large, the most important thing is a waste of energy. 8, due to improper selection of the boiler supply pump, such that the heat medium low boiler room parameters, the performance of the boiler is low lift, low thermal conductivity, insufficient heating vicious circle. 9, due to the design of overkill situation arise, ie, a single heating boiler can solve the problem, but using a more common heating boiler, resulting in low thermal efficiency of large coal consumption and generate unreasonable conditions. 10 vertical imbalance, if indoor heating system will be conducive to eliminating the balance of water resistance, which requires the designer to identify line) inputs the number of circulating pump is too large, such a large pump flow, low return temperatures, generally in 25 degree. This will increase electricity consumption. 11, about the nature of different heating buildings, commercial buildings and residential buildings if the use of a heating system is the same, then since the days of the commercial building heating requirements of large, large civil construction heating at night, if you can not time-heating, is bound to cause waste of energy. 12, single-tube heating system installed can not be achieved thermostatic valve on the radiator, but now a lot of indoor heating systems or belong to single-tube system, which is not conducive to long-term development. 161, why gas hot water heating boiler heating problems occur each year to slow the heating time, a gas boiler heating the user of the problem in many areas of heating will slow, but the problem is often not the fault based on the boiler itself. In this regard, today we elaborate on the reasons for this phenomenon. 1, because the use of gas-fired boiler heating, after carrying out the heating boiler ignition, but also need to go through the oven, cool-running, heat exchangers and other process, so as to make heating gradually warming. After the gas hot water boiler heating during ignition, the oven is ready to work early each year heating must be carried out, a process that takes about 3-5 days to complete. 2, the use of the process, gas hot water boiler also need to go through the process of heat transfer, the temperature will gradually rise. Gas heating boiler heat exchange process is mainly water cycle process, stand out from the hot water not flow directly to the residents of the home heating network, but need heat exchanger unit to transfer heat energy in the hot water heating plant to the residents of the home in the circulating pipe network. 3, starting at the initial stage of the heating boiler, water temperatures of the respective heating stations is not very high, coupled with the complex structure of the network, the gas hot water boiler heating hot water heat exchanger is a process, especially in the end of the pipe network user, heat transfer process will be a little longer time.
Combustion gas treatment and a malfunction due to gas hot water heat boiler burner ignition misfire bar: 1, the ignition bar gap interposed carbon residue with oil. 2, ignition rods fragmentation. moist. Leakage. 3, the distance between the ignition does not stick, too long or short. 4, ignition rods Insulation damage, short to ground. 5, ignition cable and transformer failure: cable, connector damage caused by a short circuit during ignition; transformer break or other fault occurs. Gas Burner fails, the action bar ignition misfire following five: Clear, renewal, adjust the distance, change and switching transformer. Second, the gas boiler the ignition spark rod misfiring but the reasons: 1, the disk space ventilation carbon cyclone is blocked, poor ventilation. 2, dirty oil nozzle clogging or wear. 3, the throttle angle is set too small. 4, the firing bar from the leading edge from the oil nozzle tip inappropriate (too protruding or retracted) 5, the first solenoid valve is an oil debris blocking gun (gun small kerosene). 6, oily or too viscous to flow easily clogged or the oil filtration system the valve is not opened, so that insufficient suction pump, oil pressure. 7, the filter pump itself blocked. 8, the oil more water (boiling abnormal noise within the heater). Gas boiler ignition spark rod action but misfiring are: clear; the first washing, such as not renewed; turndown test; adjusting the distance (in 3 ~ 4mm as well); Remove cleaning (cleaning the parts diesel) ; check the pipeline and oil filters, insulation equipment; peripheral screw pump removed, carefully remove the cover inside out net oil, diesel oil immersion; renewal of the test oil. Third, when the gas boiler and turn the fire a small fire normal, off, or flashing the causes of instability: 1, air volume damper setting fire too. 2, oil fires micro switch valve (damper outermost that group) inappropriate setting (set throttle air flow rate is greater than the fire). 3, oleaginous easy to spray viscosity is too high (heavy). 4, and the nozzle plate spacing cyclone inappropriate. 5, fire nozzle worn or dirty. 6, the preliminary fuel tank temperature is too high, so that the steam not smooth oil pump oil feed. 7, gas hot water boiler fuel oil water. When a small fire gas boiler normal and turn the fire extinguished or flashing instability action: Test gradually reduced; heating temperature; adjusting the distance (between 0 ~ 10mm); clean or replace; i.e., set to about 50 deg.] C may be; or drain oil change. Fourth, the noise increases gas boiler burner reasons: 1, cut-off valve is closed or the passage into the fuel shortage, an oil filter blockage. 2, the oil inlet temperature is low, the oil viscosity is too high or the temperature is too high the pump inlet. 3, oil pump failure. 4, fan motor bearing damage. 5, dirty fan impeller. Burner gas treatment increased noise: ① the check valve in the oil line is open, if the oil filter is working properly, the filter cleaning pump itself. ② heating oil or reduce the oil temperature. ③ Replace the oil pump. ④ replace motor or bearings. ⑤ cleaning fan wheel.Free Chat
