As far as we understand fast 15t h coal fired power boiler, Qinhuangdao City, Hebei Province to respond positively to tackling air pollution control actions, and intensive phase-out of coal-fired boilers. May 22, Qinhuangdao City Funing District launched the first action, a paper mill for a six tons of coal-fired steam boiler on-site demolition work. By Comrade Sun Guosheng, deputy director attended the action, and announced that coal-fired boiler central demolitions began.

Party Secretary Sun Zhichuan, Wang Hua district leaders to direct the demolition work, the Municipal Bureau of ecological environment, the ecological environment Branch area, technology and industrial Information Bureau, staying Town, elm Town, the next village management area, Funing town and other relevant units attended centralized demolition action.

The demolition operation was eliminated Qinhuangdao unified action to ban coal-fired boilers, Funing District is the city's main venue for the implementation of this action. 2019 coal-fired boilers area demolished 33 sets of objectives and tasks is that this concentrated action demolish 14 units, 12 sets of new coal-fired boiler investigation, a total of 26 sets of 248 tons of steam coal use is expected to reduce the amount of 149,444 tons, 145.73 tons of sulfur dioxide reduction , 439.37 tons of nitrogen oxides, soot 37.36 tons.

First, because the ash, sulfur and nitrogen content in the gas are lower than those in coal, the amount of dust in the flue gas produced after combustion is very small, and the flue gas discharged can easily meet the national standards for combustion equipment. The use of gas-fired 15t h coal fired power boilers can greatly reduce environmental pollution.

Several factors underlie the vertical steam 15t h coal fired power boiler efficiency China has been working to catch on coal to natural gas, vertical steam boiler with greatly reduced contamination of dust, smoke and other effects of a nitric oxide gas has also been healthy curb. Efficiency is an important indicator of a measure of vertical steam boiler, a good number of factors under the topic to discuss the direct impact of vertical steam boiler efficiency began. After analysis of stakeholders, heat loss from vertical steam boiler contains two pieces: the proportion of full combustion air with flue gas emissions unreasonable heat loss. Heat loss can be reduced smoke emission can be installed at the end of the vertical steam boiler stack waste heat reuse install, or more leading system with condensing boiler. Combustion air ratio sufficient unreasonable faults into: general vertical ejector-type steam boiler burner selection, resulting in a motor fuel ratio can not be adjusted. Most of the selected vertical steam boiler is mechanically strong emission combustion engine, air-fuel ratio resulting irrational factors are the following: air-fuel ratio can be divided into two reasonable chance comprising: when the air in excess, the excess will have full cold It is heated, resulting in increased operating costs vertical steam boiler, steam boiler efficiency vertical drop; when the air is not enough, will produce insufficient burning phenomenon, caused by vertical steam boiler efficiency.

The whole structure of normal pressure BoilerThe whole structure of atmospheric pressure 15t h coal fired power boiler consists of boiler body and auxiliary equipment. The main components of boiler, such as furnace, boiler barrel, burner, water-cooled wall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of steam production, which is called boiler body. The two main components of the boiler body are the furnace and the drum. The furnace, also known as the combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer furnace, also known as a bed furnace; the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber furnace, or a fire chamber furnace; the air turns coal particles into the furnace, which is called a chamber furnace, or a fire chamber furnace; the air turns the coal particles into a chamber furnace, also known as a fire chamber furnace. It is called boiling furnace, also called fluidization bed furnace, in which the furnace with boiling state and suitable for burning inferior fuel is called boiling furnace, and the cylindrical furnace which uses air flow to make coal particles rotate at high speed and burns intensively is called whirlwind furnace. The furnace design needs to take fully into account the characteristics of the fuel used. Each boiler should burn the original fuel as far as possible. The economy and reliability of boiler operation may be reduced when the fuel with different characteristics is used.
