How to Reconfigure the 150t Coal Fired Boiler
With the decreasing of natural resources in the world, every country has paid more attention to saving energy . Many coal fired boilers have been reconfigured to improve combustion efficiency, and most are replaced by environment friendly biomass fired boiler or gas fired boiler. Now I’d like to analyze the method of re-configuring 150t coal fired boiler for you.
Reconfigure 150t coal fuel boiler to gas fired boiler
The coal and gas of same calorific value are different in burning time. The coal could be burned for longer time than gas. The heat intensity of furnace volume in 150t coal fired boiler is generally 1/3 ~ l / 4 of that of gas boiler , and the furnace volume of it is larger than that of gas boiler when the capacity is same. So we know the furnace of coal fired boiler can meet the burning of gas.
Reconfigure 150t coal fuel boiler to biomass fired boiler
Low cost in fuel is the advantage of biomass fuel boiler, so burning biomass fuel can save a lot than burning gas, coal or electricity. Though it is also in layer burning style, the combustion conditions and characteristics of flue gas of biomass fuel is different from coal, so certain technical conditions are needed when burning biomass fuel in coal fired boiler.
When re-configuring coal fired boiler, pressure parts, heating surface, furnace and flue structure need not to be changed. Through promoting both fuel burning efficiency and boiler flue gas treatment, the dust in smoke and NOX emission decreased to the boiler air pollutant emission standard. In this way, the industrial boiler is more environmental friendly than before.
