circulating fluidized bed boiler in korea

Installation of fuel gas-fired circulating fluidized bed boiler in korea safety valve safety valve is one of the important requirements of the protection device fuel gas-fired boiler, boiler user is necessary for proper installation of the safety valve. Following small talk to the fuel gas boiler safety valve installation points: (1) greater than the rated 0.5t h fuel gas boiler / evaporator, at least two safety valves installed; equal to or less than the rated evaporation 0.5t / h fuel gas-fired boiler, at least install a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed. (2) safety valve should be mounted vertically at the highest position boiler drum, collection tank. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. (3) have lever-type safety valve means for preventing movement of the self-weight and deviant restriction lever guides the spring loaded safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. (4) The 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. (5) safety valve boiler tubes, which cross-sectional area not less than the cross-sectional area of ​​the valve inlet. 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. (6) 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.

After the low nitrogen gas circulating fluidized bed boiler in koreas also need to do a professional transformation maintenance it? The purpose of the transformation of low nitrogen gas boiler, is a transformation measures carried out taking into account the environmental benefits of boiler operation basis. After the low nitrogen gas boilers also need to do a professional transformation maintenance do under normal circumstances, the transformation is complete, do a discharge test, to detect the transformation of compliance with standards;? Put into operation after the transformation is complete, nitrogen oxide to be done again emissions testing to ensure normal operation, the normal and orderly discharge. Next, remove the boiler during operation in this regard, the need for regular repair and maintenance, on the one hand to avoid abnormal operation of the boiler, that is not timely phenomenon, on the one hand because the quality is not up to avoid boiler or other causes damage or corrosion and other phenomena, security risks. In short, both before the transformation of low nitrogen gas boiler or after maintenance work can not be ignored, but also to ensure the safe operation of the boiler an important task.

Xuchang City in the recently released "2018 campaign of air pollution control plan", especially for the governance of the city's circulating fluidized bed boiler in korea was planned.

Xuchang coal-fired boiler governance objectives:

In Xuchang complete basic steam 10 t / h coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, out of a planned urban area 35 steam tons / hour and coal-fired boiler.

Coal-fired boiler subsidy:

(1) the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;

(2) the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;

(3) complete Chaigai coal-fired boilers for the end of October 2020, the prize money will not give up.

Xuchang boiler out of the way:

Removal, central heating alternative, coal gas, coal to electricity, use geothermal, wind, solar, biomass with a bag filter, to burn not including clean coal, coal-water slurry, anthracite, charcoal blue, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.
