February 21 this year, the Harbin Municipal People's Government issued the "blue sky Harbin win the Battle of three-year action plan to implement the program" (hereinafter referred to as the "Program"), as follows.
First, strictly control the total coal consumption
The county (city) should shoulder the main responsibility for control of the total coal consumption, according to the focus on the use of coal and clean use of principles, focusing on reduction of non-coal power, propulsion power and other clean energy alternative to coal and oil by 2020, coal accounting for the proportion of energy consumption compared to 2015 decreased by 1.5 percentage points or more.
Second, to strengthen control bulk coal
Full implementation of the "Harbin coal pollution prevention and control regulations" to strengthen quality inspection of coal, coal quality testing organizations standardized sampling, testing system, improve the sampling frequency. Promote clean and efficient coal-fired boiler, wherein an alternative embodiment the biomass must be dedicated biomass boiler, burning raw material briquettes, installation efficient dust removal equipment.
Third, steadily promote clean heating
To promote priority to the development of clean coal utilization and clean energy use, urban urban central heating. Being difficult to cover central heating, gas heating and accelerate the implementation of electrical heating and other heating decentralized cleaning implement "coal to clean energy" units should be synchronized removal of coal-fired boiler, gas boiler for an alternative to the use of low NOx combustion technologies , gas boiler efficiency can not be less than two levels. 2019, clean heating rate of more than 60%; in 2020, clean heating rate should reach 70%.
Fourth, to carry out comprehensive improvement of coal-fired boilers
To develop a comprehensive remediation plan coal-fired boilers, the implementation of cleaner alternative to coal-fired heating boilers. 2019, the urban built-up area, county (city) county towns built-up areas out of 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal fired facilities; basic urban built-up area out of 35 tons of steam per hour coal-fired boilers; basically eliminated the urban fringe per hour 10 tons of steam coal-fired boilers; county (city) basically out of the city and county (city) financial support units (including township, village ) per hour, 10 tons of steam coal-fired boilers. By 2020, basically out of 10 tons of steam per hour urban coal-fired boilers; out of the urban built-up area per hour can not discharge standards of 35 tons of steam (or 29MW) coal-fired heating boilers. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired boilers.
Fifth, accelerate clean energy development
Orderly development of wind power, wind power construction layout optimization, to carry out decentralized wind power development and construction in the area have developed criteria. Actively promote the construction of biomass power generation. Enhanced geothermal energy exploration, development and utilization of resources to carry out detailed investigation and evaluation of geothermal energy, geothermal energy resources in the region to find out the distribution and exploitation potential. Increase renewable energy consumptive efforts to solve the basic water abandoned, abandoned wind, abandoned light problem. By 2020, the proportion of non-fossil fuels in primary energy consumption of the city's total, compared with 2017 increased by 1 percentage point.
Steam boiler heating in winter north of the advantages and disadvantages of our country, cold weather, heating is essential, often used before coal-fired boilers for heating, but coal-fired boilers to serious air pollution, now gradually replaced by fully automatic steam boilers. Steam boiler is also very common type of heating equipment, are now gradually penetrate to the south. Steam boiler heating both advantages and disadvantages, we compare: first, an analysis of the advantages of using pulverized coal combustion boiler, the coal is in fact relatively high temperature, the surface temperature of the steam boiler is relatively rapidly increased, but in fact, this system can withstand particularly low cooling system. 2, the steam in the evaporation process, as in fact it is the gas density is quite small, for which the net pressure steam boiler itself is relatively small. 3, the steam itself does not require any external pressure resistance of the propulsion system for it. 4, steam boiler has a clear advantage, the heating effect and very fast, but it stopped gas speed is faster, especially for users of intermittent heating. Second, an analysis disadvantage, during use in a steam boiler, because the pipe is relatively high stability, and is not easy to heat, in the course of prolonged use, the dust around the surface of the device, so that the relatively poor surroundings, and heat slowly dispersed, easy to burn people. 2, in a more simple production conditions, the use of the boiler does not care, and the system will cause leakage particularly large heat loss, so that the waste of energy is relatively more serious. The disadvantage of steam boilers we could have been avoided, in use of the process will be seriously careful to avoid being burned or wasted energy.
Henan difference fast boiler fully automatic steam boiler steam boiler is a steam boiler with ordinary steam production machinery and equipment, generally used gas, or coal gas as a fuel, there are an electric steam boiler. Henan fast boiler for the inspection of the steam boiler is a steam boiler gas, fuel oil, gas, and it is common conventional steam boiler with the following differences: "steam boiler supervision norms" and the forthcoming introduction in June next year the new pot rules " boiler safety technology to monitor the specifications "are clearly defined steam boiler needs to be regulated by the state. In other words, users looking to buy a steam boiler plant boiler installation and can not be used directly. Before installation To pot seized by the approval and registration required for installation, and the need for inspection on a regular basis, usually one year during the annual inspection. But there are some of the steam boiler does not require registration and annual inspection, the old rules and the new pan pot regulations stipulate a water capacity less than 30L steam boiler is not within the scope of the surveillance. Because the water capacity of 30L water capacity than at home with a water heater are also small, so there is no risk of explosion, we do not need supervision. Henan water capacity fast boiler steam boiler 26L, belongs steam boiler does not require supervision. Steam boiler explosion hazards generated is amazing. In many steam boiler explosion in the boiler room were razed to the ground, the annual explosion of a steam boiler will be the first to cause casualties and significant economic losses. Henan fast boiler steam boiler is to achieve the ultimate, the boiler body through the scientific design, water capacity is very low, only 26L, itself, there is no risk of explosion on security. The thermal efficiency of conventional steam boiler is only 80%, while the party Henan boiler thermal efficiency of fast gas steam boiler can reach more than 93%. Henan plus energy-saving system fast boiler control systems, the actual energy savings up to 30%, running down a year could save hundreds of thousands of operating costs. The Henan fast boiler steam boiler without boiler room, an area itself is small, you can put in the basement or roof, it can also be placed directly next to the device requires the use of steam. Saving the cost of laying pipe network construction costs and the boiler room, a significant reduction in the use of the initial investment.
In order to ensure boiler safety, to run smoothly, you must ensure that the use of high-quality natural gas. 1, equipped with one gas separator to increase the capacity, it can effectively store oil and water. Secondly, a level gauge designed to directly observe whether there is liquid in the separator. While the design of the automatic drain pressure relief device is installed. A single control pressure of the air is improved dual control, i.e. the pressure regulating valve is mounted on the main line to control the water separator, the pressure to stabilize, improve security purposes. 2, safety monitoring natural gas as a boiler room burning materials, natural gas leak monitoring must be done. The portable display technology poor performance, poor sensitivity. Host combustible gas alarm system with digital control scaling circuit having an alarm function and a secondary alarm, ensure the safe operation of the boiler. 3, check before firing the safe operation of: (1) whether the boiler inspection gates normally open or closed, check the gas pressure is normal, not too high or too low, open the supply valve leading to the boiler. (2) in the flue baffle must be fully open, otherwise it will affect the purge, causing accidents. Each knob and keep control cabinet to check the normal position. If the stove has a residue should be cleaned. (5) Check the boiler ignition and fire protection program control means should be flexible and reliable. Blast doors should be flexible and rigorous on the boiler. Before the completion of ignition, the ignition is not possible to start the ignition operation: After successful ignition, the load can be adjusted in the normal operation of the boiler when the combustion gas boiler adjusted. We should always observe the combustion furnace, and adjust the amount of steam, wind and steam pressure to ensure the safe operation of the boiler. Note: Program: first five minutes were furnace cleaning, automatic ignition after 5 minutes, observe the ignition is successful, the success of one minute after a small fire can be operated automatically converted to fire properly. For the boiler load and the air pressure adjusted by adjusting the pressure regulator to achieve. When adjusting the load, adjust the air pressure at the same time, it must be synchronized to adjust the air flow to ensure a reasonable match air volume and air volume, in order to achieve economic operation of the boiler. In normal operation, the amount of gas should not be adjusted or reduced drastically in order to avoid dramatic changes in combustion, the pressure receiving member sudden expansion, shrinkage and damage. When the boiler is running, the pressure gauge must be monitored regularly in order to maintain stable water pressure. BCP pressure changes observed, reflecting the relationship between water temperature and steam consumption. In the boiler operation, when the steam pressure is automatically adjusted, the main purpose of the staff is to monitor automatically adjusts the boiler system is sensitive and timely solutions to problems and ensure the sensitivity and reliability of the automatic control system. 4, first close the main valve shutdown operation, the air supply is stopped, the circulating pump and the water pump is still running, when the boiler water temperature falls below 70, and supplies or stops the circulation pump in operation of the pump after about 4 hours. Note: In addition to the accident and emergency parking stop, parking general approach should not cut off the power. After the shutdown, it is timely for the boiler and ancillary equipment to conduct a comprehensive inspection. If you find a defect in the device, and repair should be recorded at the time of shutdown. Safety Precautions 1. burner startup, if the burner is repeatedly locking and alarm, you should find out the cause of the malfunction, press the reset button after troubleshooting, press the reset button and then continue to boot. Note: Press the Reset button for less than 10 seconds. A lower burner inlet must be clean and clean, and does not allow offal. 2. burner once the ignition is unsuccessful, Boiler Fan should be restarted. Ventilation After 5 minutes, start the second startup burner igniter. three. During normal operation, the thermal device near the burner portion (e.g. flange connections) will be very hot, in order to avoid burns. Do not put flammable materials in the vicinity so as not to cause a fire. 4. The operation of the boiler circulating pump must be closely monitored and the hot water boiler pressure, gas distributor, pipeline valves, pressure gauges, flow meters, water level gauge and the like. 5. When the firefighters open the door or fire door observation, you should wear gloves and a side view. 6. A burner working environment should be kept clean and dry, in particular, a flame detector (i.e. electric eye) should be kept clean, part of the control circuit should humidity and temperature; class should cleaning and maintenance of a combustor. 7. During use, the filter should be cleaned regularly check or replace the filter cartridge in accordance with impurities of the fuel. 8. Check the electrical installations include: wire is damaged, the sheath is damaged, the screw is loose, the contact is good, whether the motor is running abnormal noise. Describes the advantages and disadvantages of natural gas boiler, editor of Sin sets introduced, the use of technology and safety precautions. Industrial boilers to energy efficient, environmentally friendly development direction. Natural gas boiler to meet the needs of these three points. They are the future of the boiler market trend, more and more restricted energy policy, energy saving and environmental protection requirements.Free Chat
