QXX Industrial Coal Fired CFB Hot Water Boiler
Capacity: 14-58 MW
Pressure: 1.25 – 1.6 Mpa
Temperature: 95/70℃, 115/70℃
Fuel: Coal, rock refuse, biomass, sludge
Industries: Centralized heating
CFBC technology is a new, efficient, and low-pollution clean coal method. This low-temperature combustion significantly reduces Nitrogen Oxide emissions and enables direct, high-efficiency desulfurization. Economically straightforward, CFBC lowers costs compared to other methods and accommodates various fuels, including low-calorific, low-quality coal. The resulting ash is reusable, eliminating secondary pollution. Moreover, CFBC supports wide load adjustments, operating down to about 30% of full load.
Extensive Fuel Adaptability
The circulating fluidized bed is a fast bed, which can keep the temperature in the furnace uniform and keep the same, and the fuel can burn immediately when it enters the furnace. Therefore, the circulating fluidized bed can burn all kinds of fuel without auxiliary fuel, which has good fuel adaptability.
High Efficiency
The industrial coal fired boiler has a circulation separation device, after continuous optimization and improvement, the efficiency of the separator is up to 99%, the thermal efficiency of the boiler is also up to 85%, the combustion efficiency is above 98%.
Wide Range of Boiler Load Regulation
A large amount of hot bed material reserve so that the fluidized bed hot water boiler has a good load regulation performance, load regulation range.
Environmental Protection
Due to the characteristics of low-temperature combustion of fluidized bed boiler, the generation and emission of SO2 and NOX can be effectively suppressed, and the desulfurization rate of about 90% can be achieved with proper amount of limestone. Therefore, this economical and effective low-pollution coal burning technology has been widely applied in the world.
