Biomass furnaces are a type of industrial furnaces that mainly burn biomass fuels and are used to achieve industrial hot water, steam, heating, power generation and other needs. As far as the biomass furnace is concerned, it can be divided into different types according to different standards.
If according to the purpose, biomass furnaces are divided into two types: biomass thermal furnaces and biomass electric furnaces. In fact, the principles of the two are basically the same. They both obtain energy by burning biomass fuel. This converts thermal energy into electrical energy. Among these two furnaces, the first is the most widely used and the technology is more mature.
If you continue to subdivide, the first type of furnace, the biomass thermal energy furnace, can also be divided into three categories:
The first category: small-scale biomass thermal energy furnaces: This type of furnace 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 disadvantage is that the energy loss is large. The fuel consumption is large, the heat energy supply is low, and users who cannot meet the large heat energy demand are targeted for heating and domestic hot water supply for single-family rural households.
The second category: medium-sized biomass thermal furnaces: This type of furnace mainly uses solidified biomass fuel to provide hot water or steam. Its advantages are relatively mature technology, low energy loss, and strong heat energy supply capacity; its disadvantages are that some furnace fuels are coked and the supporting design is unreasonable.
The third category: large-scale biomass thermal furnaces: There are no actual products for this type of furnace, mainly because the existing technology is not perfect, and the national policy for replacing coal with biomass is not complete, so it stays on the concept. What it emphasizes is a kind of centralized management and control of thermal energy engineering. The furnace 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 are very high.
Biomass furnaces comply with the current trend of energy conservation, emission reduction, and low-carbon environmental protection, and are an effective form of resource utilization. Our Institute has developed a large furnace suitable for straw biomass, which avoids or solves the problems of ash accumulation and slagging during biomass combustion and heat exchange. The emission of flue gas meets the relevant national environmental protection standards, and the ash residue has a low carbon content, which can realize the comprehensive utilization of fly ash.
