In terms of boiler types, some have already been mentioned earlier, including hot water boilers, steam boilers, etc. However, the types are far more than these. So, next, let’s get to know another type, which is the biomass boiler so that everyone can make breakthroughs and expansions in boiler types.
The biomass boiler can be said to be a major category among boilers. Specifically speaking, it is a kind of boiler that uses biomass energy as fuel to provide heat, etc. And, in terms of specific types, generally speaking, it can be divided into two major categories: vertical and horizontal. Moreover, from another perspective of classification, then, biomass boilers can be divided into steam boilers, hot water boilers, and heat-conducting oil furnaces, etc.
1.Characteristics of biomass boilers
For this type of biomass boiler, in terms of characteristics, the main thing is that in the structural design, compared with traditional boilers, there is a larger furnace space, and the internal secondary air arrangement is reasonable, which is conducive to the full combustion of biomass. In addition, in terms of combustion equipment, a reciprocating grate furnace is adopted, which can ensure the combustion effect.
2.Fuel supply of biomass boilers
In biomass boilers, for the fuel it uses, it is mainly BMF fuel. And, it is sent into the furnace top bunker by the conveyor and then sent into the furnace of this boiler by the screw feeder, so that it can be evenly scattered on the grate to enable it to fully combust.
3.Working efficiency of biomass boilers
The working efficiency of biomass boilers is generally above 80%. Moreover, if the boiler model is large, then the combustion effect can be improved, thereby increasing the boiler efficiency, and even reaching 88.3%. Therefore, compared with coal-fired boilers, it has been greatly improved.
4.Environmental protection emissions of biomass boilers
For this type of boiler, if it wants to avoid pollution and achieve environmentally friendly emissions, then some measures can be taken in the boiler. For example, a slag extractor with a screw is arranged at the rear of the boiler to achieve continuous ash removal. Also, a dust collector is arranged in the flue at the tail of the boiler to ensure that the smoke and dust emissions meet the standards and thereby avoid environmental pollution, etc.
