Biomass boilers are roughly divided into two categories according to their uses: one is biomass thermal energy boiler, and the other is biomass electric boiler.

In fact, the principles of the two are basically the same. Both obtain energy by burning biomass fuel, but the first one directly obtains heat energy, and the second one converts heat energy into electrical energy. Among the two types of boilers, the first one is the most widely used and the technology is relatively mature.

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

The first 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; the 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 at heating and domestic hot water supply for single rural households.

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

The third category: large-scale biomass thermal energy boiler. 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.
