The difference between biomass boiler and coal boiler?

The difference between biomass boiler and coal boiler?

1. Biofuel combustion fuel caused by boiler load
The reason why the biomass boiler is clean and environmental protection is that its fuel is biomass pellet fuel, this fuel is made of agricultural and forestry straw waste after processing, clean combustion and pollution-free; The coal burning boiler uses the ore fuel coal, which produces more dust, sulfur oxide and nitrogen oxide. Biomass boiler burning biomass pellet fuel, less polluting pollutants, so it has higher environmental advantages; However, coal-fired boilers emit more polluting gases, causing great environmental pollution and ecological destruction.
Although the biomass boiler burning clean, but compared with the coal-fired boiler, the load is low, has not developed to a very mature stage, especially Hebei Yaoyi energy saving and environmental protection Equipment Co., Ltd. chain grate coal-fired boiler overload capacity, sufficient processing.

2. The difference of energy in boiler use cost in actual operation
Coal quality of coal-burning boiler fluctuates easily and there are some problems in coal quantity measurement. The average operating efficiency of the actual layer fired boilers (chain boilers below 20T) is lower than 70%, and some of the boilers are even lower than 60%, due to the boiler body design, the operating level of the furnace personnel, the unstable coal quality, ash accumulation and other reasons. It is estimated that the converted cost of electricity consumption, slag removal and dust removal water consumption, labor and maintenance parts of coal-fired boilers is about 20 yuan/ton of steam.
Biomass boiler combustion raw material composition is complex, processing methods are different, so its calorific value fluctuation is large, and for energy saving and emission reduction control of environmental pollution, has high economic and social benefits, the cost must be high.

3. The fuel used in the boiler is different
The coal fuel supply used in coal-fired boilers is guaranteed, the technology is mature, the furnace personnel are familiar with it, and the operation cost is low.
