There are many types of coal fired boilers, and the pressure is also free to choose. which leads to the fact that the coal consumption of a 20ton CFB coal fired steam boiler is not the same. Calculation formula of coal consumption of coal-fired boilers: coal consumption per hour = boiler thermal power *3600/ combustion value of coal/boiler efficiency
According to this formula, the user can roughly calculate the coal consumption of the boiler. For example, for SHL20-1.25-AⅡ, the thermal capacity of the boiler is 14MW, and the heating value of bituminous coal is generally between 27170～37200kj/kg. We take the intermediate value 22.3MJ/kg to calculate. The design thermal efficiency of ZOZEN Boiler Plant SHL20-1.25-AⅡ is 80%, then the formula: 14MW*3600/22.3MJ/80%=2825kg.
As one of the most important fuels in the world, coal has the advantages of large reserves, stable supply and low price. It can provide continuous heat energy for enterprises, so that enterprises will not stop production due to insufficient heat energy. Chain grate coal-fired boilers are suitable for a variety of fuels, mainly lumps of coal, but can also burn biomass pellets, cloth, bagasse and other relatively small solid fuels.
Coal fired boilers with chain grate are usually equipped with accessories such as coal gates, coal feeder, blower, induced draft fan, reducer, economizer, water treatment equipment, feed pump, etc. If you want to save energy and reduce emissions, you can be equipped with condensate recovery equipment. The thermal efficiency of a chain grate boiler varies from 82% to 85% depending on the fuel.
ZOZEN has been engaged in industrial boiler production for more than 35 years and has a wealth of experience. At present, our main products include hot water boilers, thermal oil boilers, steam boilers and boiler auxiliaries. Through our efforts, ZOZEN boilers have been exported to more than 100 countries and regions. To better serve our customers, we have offices in many countries and we are still recruiting boiler agents!
Chain grate boiler is especially suitable for countries and regions with unstable gas source, no good alternative fuel or low emission requirement. A chain-grate coal boiler USES a steel grate, like a furnace rail, to move coal slowly into the interior of the furnace and heat the boiler through the burning of coal seams. It is used in the production of industrial or daily hot water and steam. The ZOZEN boiler has been unanimously approved by its users. We also take “make the product that you want, make you and your business more dynamic” as our mission. To provide customers with more valuable high-tech boilers!
