The large agricultural provinces are rich in biomass fuels and their prices are relatively low. Therefore, biomass boilers are also industrial boilers that are vigorously promoted and used in Northeast provinces. Although the fuel price is low, if you want to reduce the operating cost of a biomass boiler, you also need to choose a boiler with high thermal efficiency. So, which kind of biomass boiler has high thermal efficiency?

1. Biomass boiler selection
The selection of biomass boilers is very important. For biomass boilers of 4-30 tons, chain grate boilers can be selected; biomass boilers of more than 30 tons can be biomass circulating fluidized bed boilers.
Biomass chain grate boiler has the following models: SZL chain grate boiler, DZL chain grate boiler, DHL angle tube chain grate boiler, etc.
Biomass circulating fluidized bed boilers have the following types: rice husks, straws, and biomass power boilers, vinasse and bagasse hydrous biomass boilers, etc.

2. Which kind of biomass boiler has high thermal efficiency?
The boiler capacity of the biomass chain furnace is 4-170 tons, and the thermal efficiency is generally between 78-83%. The boiler capacity can be customized according to customer needs. At the same time, the boiler efficiency can be improved for customers on the basis of current technology research and development. .
The capacity of the biomass circulating fluidized bed boiler is 8-410 tons, and the thermal efficiency is generally between 88-92%. At present, biomass circulating fluidized bed boilers are mainly used in biomass cogeneration projects. 35 tons of biomass circulating fluidized bed boilers, 75 tons of biomass circulating fluidized bed boilers, and 130 tons of biomass circulating fluidized bed boilers are domestic Biomass cogeneration projects purchase more biomass boilers.
From the above explanation, we can see that the thermal efficiency of the biomass circulating fluidized bed boiler is much higher than that of the biomass chain furnace. This is because the circulating fluidized bed boiler has a large furnace area, sufficient fuel combustion, and can be cyclically burned. This greatly improves the thermal efficiency of the boiler.

3. Application fields of biomass boilers
There are two types of biomass boilers: hot water boilers and steam boilers. Biomass hot water boilers can be used for central heating and hot water supply in schools, hospitals, communities, government units, etc.; biomass steam boilers can be used in food plants, pharmaceutical plants, and building materials. Drying extraction, high-temperature steam sterilization in factories, garment factories, etc.
