Types of biomass boilers

　　Biomass boilers are roughly divided into two categories according to their uses: one is biomass thermal energy boilers, and the other is biomass electric power boilers. In fact, the principles of the two are basically the same. They both obtain energy by burning biomass fuel, but one directly obtains heat energy, and the two convert heat energy into electrical energy. Among the two types of boilers, one is widely used and has relatively mature technology.

　　If you continue to subdivide, a kind of boiler-biomass thermal energy boiler, can also be divided into three categories:

　　One category: small biomass thermal energy boiler. This kind of boiler uses solidified or gasified biomass fuel to provide thermal energy in the form of hot water. Its advantages are small size, simple structure, and low price; its disadvantages are large energy loss, large fuel consumption, and low heat energy supply. Unable to meet users with large thermal energy demand, this type of boiler aims to provide heating and domestic hot water supply for single rural households.

　　Second category: medium-sized biomass thermal boiler. This type of boiler mainly uses solidified biomass fuel to provide hot water or steam. Its advantage is that the technology is relatively mature, the energy loss is small, and the heat energy supply capacity is relatively strong; the disadvantage is that some boiler fuels are coking, and the supporting design is unreasonable.

　　Three categories: large-scale biomass thermal energy boilers. This type of boiler has no actual product, mainly because the existing technology is not perfect, and the national policy for biomass substitution of coal is not sound, so it only stays in the concept. What it emphasizes is a thermal energy project with centralized management and centralized control. The boiler is only one of the equipment to ensure the normal operation of the entire biomass thermal energy project. Therefore, it requires fuel, combustion technology, supporting technology, and related policies. Very high.
