electricity economizer for coal power plant boiler

BOILERS deposited combustible material, such as carbon black, oils idle, coal, etc., it is mainly due to incomplete combustion of the tail into the electricity economizer for coal power plant boiler. Especially when the ignition and shutdown, most likely to cause incomplete combustion, the rear of the boiler deposited a large amount of combustible material. These deposits reduce the heat transfer surface of the tail heating the exhaust gas temperature rises. When the exhaust gas temperature rises to a certain value, there is sufficient oxygen combustion condition occurs at the secondary combustion, secondary combustion is in the shutdown some minutes or hours after the occurrence, which is the ignition point of combustible material and heat conditions. Running faster flow of the flue boiler, heat of the combustible substances produced smoke away quickly, only a slow oxidative, ignition combustion can not be achieved. After the shutdown, the gas flue, the flow is stopped, the heat generated by the oxidation of combustible material not easily lost, the temperature will rise. If the door or flue damper closed tightly, leakage into the fresh air for combustion, causing secondary combustion after shutdown.

Coal-fired electricity economizer for coal power plant boiler to gas boiler advantages: China's major coal-fired boilers used to be the life of heating and industrial boilers being used. Total annual use of coal because coal-fired boilers consumed 600 million tons. According to incomplete statistics, China's total industrial coal-fired boilers is 60 million units. Visible large proportion of coal-fired boilers in China's industrial life, the breadth of coverage. The thermal efficiency of the boiler runs produced generally much lower than the gas boiler, emissions has doubled. Therefore, the transformation of coal-fired boilers to gas-fired boiler is imperative. From central to local government organs at all levels to join all the positive trend of the gas boiler of them, in order to reduce emissions, improve production efficiency to do their part.

In most people's concept, the electricity economizer for coal power plant boiler is "silly, big, stupid, thick" representative. But in the fast boiler, but it will completely subvert the concept. When you first meet with the parties boiler fast, never thought the equipment was actually in front of a boiler. They look neat and clean, the overall design is very smooth, the boiler is also not "clumsy" shadow. Mr. Lu Haiqing Group Chairman, says: "Right now, we have four types of enterprises, more than 200 kinds boiler models, innovation and creativity we have tasted the sweetness." The face of fierce market competition, the fast side of the family must go deeply understand the creation of independent innovation road to seek greater development. We respond positively to national development strategies, investment in research on clean and environmentally friendly gas boiler, set up research cooperation with Tsinghua University base, development pattern of innovation and development of new products.

Power plant electricity economizer for coal power plant boiler working principle

Power station boilers are an indispensable device in thermal power plants. They generate high-temperature and high-pressure steam by burning various fuels (coal, oil, natural gas, biomass fuel, etc.). This steam is used to drive a steam turbine. Generator attached to the steam turbine generating electricity.
