What type of fuel is used for biomass boilers? What is the model classification of biomass boilers? How to choose a biomass boiler
Among numerous boilers, biomass boilers quickly emerged, occupying a market share with their characteristics of green, low nitrogen, environmental protection, and energy conservation, responding to the major decision and deployment of the 19th National Congress of the Communist Party of China to “win the battle to defend the blue sky”.
The thermal efficiency of biomass boilers is 83%, and the generated ash content is around 1.5%. The biomass boiler is equipped with a spiral slag extractor at the rear to achieve continuous ash cleaning. The installation of dust collectors in the tail flue can ensure that the emission of smoke and dust meets the national environmental protection requirements.
The fuel selection for biomass boilers is very extensive. It compresses crop waste such as corn cobs, corn stalks, peanut shells, rice husks, and rice stalks into biomass pellets to provide biomass boilers with fuel. The ash content produced after the combustion of different biomass is also different.
Biomass boilers can be classified into biomass thermal boilers and biomass electric boilers according to their uses. The working principles of these two types of boilers are basically the same, but biomass thermal boilers directly obtain heat energy; Biomass electric boilers convert thermal energy into electrical energy.
Biomass thermal boilers can also be divided into:
Small biomass thermal boiler: suitable for rural household hot water supply and heating, using solidified or gasified biomass as fuel.
Medium sized biomass thermal boiler: This type of boiler currently has more mature technology compared to the other two types of boilers, with low energy consumption and strong ability in thermal energy supply.
Large scale biomass thermal boiler: Currently, it is still in the conceptual stage and has not been practically produced. It emphasizes centralized management and control of thermal energy engineering.
We can start from several aspects when choosing a biomass boiler, such as the boiler burner, the thickness of the furnace steel plate, and the packaging of the furnace body!
