Battle to win the blue sky, is the major decisions and plans to make a big party in the nineteenth, and is for building a moderately prosperous society, to improve the quality of life of citizens and establish a beautiful China's development goals. To fully implement the nineteen spirit, promote the governance of air pollution intensity and improve the living quality of the environment, this year March 8, Zhengzhou Municipal Party Committee General Office, Zhengzhou Municipal People's Government Office issued the 2018 air pollution control program and the corresponding subsidy policy, the implementation of low-nitrogen gas fedd water dan steam outlet boiler cfb retrofit demonstration project, as follows:

Before the end of September 2018, the city's more than 20 tons of steam (with), and the urban areas more than 4 tons of steam (with) the completion of gas-fired low-nitrogen transformation project demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out in accordance with the 40% investment in equipment;

Before the end of September 2018, the city's more than 4 tons of steam (with), and the urban areas more than 2 tons of steam (including) low nitrogen gas boiler reconstruction project completed demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out according to 30% of equipment investment;

Before the end of April 2019, the city completed all gas-fired low-nitrogen transformation, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, the municipal finances awards complement of 15% investment in equipment.

gas-fired thermal oil heater (YQW-9400Q) to replace the original

coal-fired boiler, which is highly efficient and can also save energy and

4, small steam fedd water dan steam outlet boiler cfb should be conducted every two years external inspection and hydrostatic test.

5, small steam boiler lifespan should not exceed eight years, more than eight years be scrapped.

6, small aluminum pressure hydraulic test should be conducted every two years. Prior to hydrostatic testing should be performed to check the necessary internal and external.

7, after pressure hot water boiler in use, and no unit or person shall not change the structure and installation of boiler system piping, valves.

What safety protection devices are available for electric steam fedd water dan steam outlet boiler cfbsSteam boilers are mechanical equipment that uses heat from fuel or other energy sources to heat water into hot water or steam. The original meaning of the pot refers to the water-holding vessel heated on the fire, the furnace refers to the place where the fuel is burned, the boiler includes two parts of the boiler and the furnace. 1 leakage protection: when the boiler leakage occurs, the power supply is cut off in time through the leakage circuit breaker. To ensure personal safety. 2 Water shortage protection: when the boiler is short of water, the heating tube control circuit is cut off in time to prevent the heating tube from being damaged by dry burning. At the same time, the controller sends out a water shortage alarm indicating 4 steam overpressure protection: when the boiler steam pressure exceeds the set upper limit pressure, the safety valve starts, releasing the steam to make the pressure Force reduction-5 over-current protection: when the boiler is overloaded (overvoltage), the leakage circuit breaker automatically disconnects. 6 Power supply protection: with the help of advanced electronic lines, the overvoltage, under-voltage, and off-equal fault state are detected, Provide reliable power-off protection.
