Biomass pellet fuel, as a renewable resource, has the characteristics of environmental protection and sustainability, so it has been widely concerned in the field of energy. However, the combustion process of Biomass pellet fuel often has problems such as low efficiency and large emissions, which restricts its large-scale application. Based on the basic principle of Biomass pellet fuel combustion, this paper discusses how to optimize its combustion process, improve energy efficiency and reduce environmental pollution.
First, the basic principle of Biomass pellet fuel combustion
Biomass pellet fuel is mainly composed of cellulose, hemicellulose and lignin, and its combustion process mainly includes four stages: preheating, volatilizing analysis, ignition combustion and coke combustion. During the combustion process, elements such as carbon and hydrogen in the Biomass pellet fuel react chemically with oxygen in the air to generate products such as carbon dioxide and water, while releasing a lot of heat energy.

The quality of Biomass pellet fuel directly affects its combustion effect. Therefore, the primary measure to optimize the combustion process of Biomass pellet fuel is to improve the fuel quality. The uniformity, moisture content and calorific value of fuel can be improved by screening, crushing, drying and other pretreatment methods, which is conducive to the smooth combustion reaction.
2. Optimize combustion equipment
The performance of combustion equipment has an important influence on the combustion effect of Biomass pellet fuel. The optimization of combustion equipment can be started from the following aspects: first, the selection of high-efficiency and low-pollution burners to improve the combustion temperature and flame stability; The second is to optimize the combustion chamber structure to make the fuel evenly distributed in the combustion chamber and improve the combustion efficiency; The third is to increase secondary air and other auxiliary facilities to promote the full mixing of fuel and oxygen and increase the combustion speed.
3. Adjust the combustion parameters
The adjustment of combustion parameters has an important effect on the combustion process of Biomass pellet fuels. The optimization of combustion process can be realized by adjusting the parameters of air quantity and fuel feeding speed during combustion. The reasonable amount of air can ensure the full combustion of fuel and reduce the generation of incomplete combustion products; The proper fuel feeding speed can ensure the uniformity of fuel distribution in the combustion chamber and avoid local overheating or flameout in the combustion process.
4. Strengthen heat transfer during combustion
Strengthening the heat transfer in the combustion process is a key measure to improve the combustion efficiency of Biomass pellet fuel. By increasing the heat exchange area in the combustion chamber and optimizing the structure of the heat exchanger, the heat transfer efficiency in the combustion process can be improved, so as to improve the combustion efficiency of Biomass pellet fuel.
The mixed combustion technology of biomass and coal can realize collaborative combustion of Biomass pellet fuel and coal, improve combustion efficiency and reduce pollutant emission
5. Develop new combustion technology
With the continuous development of science and technology, new combustion technologies continue to emerge, providing a new way to optimize the combustion process of Biomass pellet fuel. For example, biomass gasification technology can convert Biomass pellet fuel into gas to achieve efficient and clean combustion; The mixed combustion technology of biomass and coal can realize collaborative combustion of Biomass pellet fuel and coal, improve combustion efficiency and reduce pollutant emission.
Optimizing the combustion process of Biomass pellet fuel is of great significance for improving energy utilization efficiency and reducing environmental pollution. Measures such as improving fuel quality, optimizing combustion equipment, adjusting combustion parameters, strengthening heat transfer and developing new combustion technologies can effectively improve the combustion efficiency of Biomass pellet fuel, reduce pollutant emissions, and promote the wide application of Biomass pellet fuel in the energy field. In the future, with the continuous progress of science and technology and the continuous support of policies, it is believed that Biomass pellet fuel will occupy a more important position in the global energy structure.
