Principles and Characteristics of Biomass Boiler

As the thermal equipment using renewable energy, the biomass boiler can meet the demand of heating and power generation by converting the biomass fuel into heat energy. Its working principle is based on fuel combustion and energy conversion, and its unique characteristics make it have obvious advantages in the field of environmental protection and energy.

The working principle of the biomass boiler is combustion oriented. Straw, wood chips and other biomass fuels are sent into the furnace through the feeding device, fully mixed with air and burned to release a large amount of heat energy. These heat energy are transmitted to the internal working medium through the heating surface in the boiler, such as water wall and superheater, to heat the water into hot water or steam. Ash and slag produced by combustion are discharged by the ash discharge device, and the flue gas is discharged after dust removal and purification. Different types of biomass boilers, such as layer combustion boiler and fluidized bed boiler, have their own characteristics in terms of combustion modes, but they are all developed around efficient combustion and energy absorption.

In terms of characteristics, the environmental protection of the biomass boiler is particularly outstanding. The biomass fuel has a low sulfur content and a low emission of pollutants such as sulfur dioxide during combustion. In addition, the plant growth process absorbs carbon dioxide to form a carbon cycle and reduce the net emission of greenhouse gases. With strong fuel adaptability, it can utilize various agricultural and forestry wastes, which not only solves the waste treatment problem, but also reduces the fuel cost. In addition, compared with traditional coal-fired boilers, the operating cost of biomass boilers is more economical in some regions, which can help the energy structure transform to the renewable direction.

From principle to characteristics, the biomass boiler provides a new path for energy utilization by virtue of its advantages of cleanness, economy and high efficiency, and plays an important role in the energy system of sustainable development.
