france bituminous coal fired boiler for sale
BOILERS deposited combustible material, such as carbon black, oils idle, coal, etc., it is mainly due to incomplete combustion of the tail into the france bituminous coal fired boiler for sale. 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.
Still 8 cultural and creative industrial park is located in the Chaoyang District, Beijing, Bali Zhuang Chen Lin, No. 2, construction area of 493,300 square meters. Surrounded by quintessence of Court, Red Sandalwood Museum, Shanxi Museum and other famous attractions. Due to its special geographical location, has very stringent requirements for providing heat france bituminous coal fired boiler for sale plants. Carefully selected to finalize cooperation with our company, signed a two He Lide series complete condensation pressure hot water boiler.
ZG as a 70 years biomass coal fired CFB france bituminous coal fired boiler for sale manufacturer has a high technology on circulating fluidized bed. During the combustion phase, upwards jets of air will cause the solid fuels to be suspended. This is to ensure the gas and solids will mix together turbulently for better heat transfer and chemical reactions. The fuel will be burnt at a temperature if 1400oF to 1700oF to prevent nitrogen oxide from forming.While burning, flue gas such as sulfur dioxide will be released. At the same time, sulfur-absorbing chemical such as limestone or dolomite will be used to mix with the fuel particles in the fluidization phase, which will absorb almost 95% of the sulfur pollutants.
There are two main components of a combustion–based biomass plant: 1) the biomass-fired france bituminous coal fired boiler for sale thatproduces steam; and 2) the steam turbine, which is then used to generate electricity.The two most common forms of boilers are stoker and fluidised bed. These can be fuelled entirely by biomass or can be co-fired with a combination of biomass and coal or other solid fuels.
