1, while maintaining the original nominal parameters of the boiler (e.g., steam temperature, steam pressure, water temperature, etc.) remain unchanged, maintaining or improving output and efficiency of the boiler.
Layer burning coal combustion boiler, the coal through the coal chain grate conveyor plane, the complete combustion process in the furnace. While the combustion gas boiler combustion chamber, the gas is mixed with air in advance is set in proportion to the burner, injected into the furnace through a nozzle, the torch was installed in the furnace to complete combustion. 2. Combustion of Coal mainly by c, H, s, 0, N, and other elements composed of ash and water, but not the mechanical mixing of these components, but a very complex compound. Coal combustion heat release, and smoke into the atmosphere by the SO²SO³NOx generated, environmental pollution, harm to humans the main component of natural gas is methane (CH.) Gas, and a small amount of non-hydrocarbon gases. Generally free of moisture and ash after the combustion of natural gas, produce mainly water co2 and emit a lot of heat, deleterious SO2, SO3Nox other emissions is relatively much less coal.
To further reduce emissions of air pollutants and improve air quality of the environment, the Shanghai Municipal People's Government Office issued the "Opinions on accelerating the transformation of the city mentioned standard boilers of small and medium" (hereinafter "Opinion"), to accelerate the introduction of Shanghai City small boilers mentioned standard transformation respond positively.
Before the end of 2018, the district in conjunction with boilers and industrial distribution block, complete the development and revision of the Gas Pipeline Network Planning in this area. City, district authorities, according to the unit Gas Pipeline Network Planning and excavation plan, speed up the construction of natural gas pipeline network.
Variety of boiler fuel to replace natural gas, natural gas pipeline network (municipal pipe network to users outside the red line pipe) 50% of the cost of laying borne by the gas company; the remaining 50% by the district government and users each pay half, and encourage qualified district to provide more support. On the outskirts of the gas pipeline construction is temporarily unable to reach enterprises in the region, while ensuring security compliance cases, it can be in the form of non-natural gas pipeline, and implement an orderly transition after the completion of the pipe network. Encourage alternative gas supply business enterprises to provide gas price discount for the gas boiler.
10KV for the implementation of alternative electric boiler, 35KV and other business expansion project, to which the power supply capacity of the electrical part of the boiler, according to the city's non-resident business expansion project quota standards, engineering fees charged by half.
Environment departments to strengthen law enforcement and inspection of boiler units, fuel use, operation and maintenance, equipment maintenance, inspection, non-functioning facility once found, according to the law severely punished; at the same time, strengthen supervision and monitoring, if it is found excessive emissions, according to law strict punishment.
Boiler units and boiler mentioned standard transformation service units bear the main responsibility for the boiler safety issues involved. Site construction unit must have the appropriate boiler manufacture or installation (reconstruction) qualification, boiler commissioning personnel must have the appropriate special equipment operator certificate. Prior to the construction site mentioned standard boiler units to implement the transformation, boiler location should be informed in writing of special equipment regulatory authorities.
The district government is the responsibility of the main boiler to mention the transformation of the standard, according to the "ground principles" to promote the transformation of the boiler. Combined with the actual circumstances of the district reform implementation plan, accelerating the construction of facilities to ensure timely completion of the task of transformation, to ensure that policies and financial support in place.
At the same time the 58MW circulating fluidized bed 2 mw coal fired hot water boiler has good fuel adaptability, not only with the bituminous coal, lignite and other flammable combustible coal, also can use anthracite coal, can also burn bark, garbage and other biomass fuels, the heating company to buy fuel way is broad.
