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.

Fuel gas-fired boiler fuel gas-fired boiler product presentation is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. Oil injected into the furnace, if the gas and air mixture within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a distribution box, it may also be assembled and medium-sized factory. Fuel gas-fired boiler safety valve installation points introduce fuel gas-fired boiler safety valve needs to be installed in the correct installation steps, in order to avoid mistakes, resulting in what needs to pay attention to danger, fuel gas-fired boiler safety valve installed it? Here, I introduce: 1 fuel gas boiler safety valve should prevent the lever means and movement of the self-weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly . 2. Rated to 0.5t h evaporation boiler fuel gas /, at least two safety valves installed; Rated evaporation 0.5t h or less fuel gas boiler /, mounted on at least a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed. 3. Fuel gas-fired boiler safety valve to the boiler tubes, cross-sectional area should not be less than the import safety valve cross-sectional area. If several valves installed together with a short tube directly connected to the drum, short tube passage area not less than 1.25 times the area of ​​all the exhaust valve. 4. Fuel gas boiler safety valve should be installed vertically in the boiler drum, header high position. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. 6. Fuel gas-fired boiler safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. Safety valve exhaust pipe at the bottom should be fitted to the safe location of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.

What impact have fuel moisture fired steam boiler seller? Most of the aqueous fuel when coal or heavy oil with steam atomization of entrained moisture in an amount not more than 5%, no effect on the coil and the inner shell boiler, the boiler because their materials are steel, steel are mainly: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng, with a strong antioxidant, water resistance. With more moisture, combustion performance worse, if the moisture up to 40% burn will be extinguished.

(Iii) use of a waste heat boiler for heat recovery. Using the waste heat boiler using waste heat discharged from the heat of the flue gas in a boiler to heat water or generate steam. Such waste heat boiler is provided thermal oil furnace itself does not change the fuel consumption, the waste heat boiler to produce steam or hot water may be used for the production and the occurrence of heating, thereby indirectly ADSF fuel savings. A waste heat boiler provided the following effects: First, since the heat recovery water, it is easy to improve the thermal efficiency of the furnace. Second, because the number of boiler flue gas can be centralized heat recovery, thereby reducing the cost of construction of the heat recovery unit.
