Description

* Circulating fluidized bed boiler are low temperature combustion, so emissions of nitrogen oxides is far less than the pulverized coal, the combustion process can achieve direct desulfurization, desulfurization efficiency, and economy of technical equipment simple.

* Coal combustion and wide adaptability and high efficiency, low quality coal suitable for low calorific value.

* Discharge of ash activity, and easy to realize the comprehensive utilization of ash no secondary pollution.

* Line regulation range, low compliance may be reduced to about 30% of full load.
