Biomass power generation is a method to realize biomass generator and recycling power generation by using renewable biomass resources, such as waste incineration power generation, agricultural and forestry waste gasification power generation, or power generation by using biogas and landfill gas. Compared with traditional power generation modes such as thermal power generation, biomass power generation can effectively realize energy recycling, turn waste into treasure and save energy. Moreover, the power generation fuel is renewable, which is conducive to the sustainable development of China’s power industry. At the same time, biomass power generation also has higher cleanliness and is in line with China’s low-carbon and environmental protection development strategy. In recent years, biomass power generation has been widely popularized and applied, effectively alleviating the problem of existing energy shortage, It can also reduce environmental pollution at the same time. It is a power generation means to achieve a win-win situation.
Common biomass power generation methods
At present, the most widely used biomass power generation method in China is biogas power generation method. Its principle is to ferment the waste through anaerobic fermentation technology to generate biogas, and then use biogas to promote the stable operation of the generator to achieve the effect of power generation. Due to the high stability of this method, the popularity is relatively large. Secondly, there is biomass gasification power generation method. The function principle of this technology is to place biomass in the gasifier to convert it into combustible gas. After purification, it is put into the gas engine as fuel to maintain the operation of the combustion engine, so as to realize the power generation effect. It can also be directly rushed into the fuel cell for power generation. The main point of gasification power generation technology is to ensure the degree of gas purification. Since the initial gasification of gas will contain impurities such as coke, ash and tar, if used directly, it may accelerate the aging of equipment and cause environmental pollution. Therefore, after the gasification of biomass, a certain essence must be treated before it can be used as fuel.
Moreover, biomass can also be mixed with other fuels for power generation, such as coal. This technology is called biomass mixed combustion power generation method. There are two main mixing methods. One is to directly mix coal and biomass as the combustion medium, but the implementation process of this method has high requirements for combustion equipment and combustion treatment links, which can not be realized by some small power generation enterprises, so the application scope is not very wide; The other is to mix the vaporized biomass and coal as combustion materials, and inject the burned steam into the steam turbine generator to realize the power generation function. This method has higher practical operability.
In addition, direct combustion of biomass for power generation is also a power generation method, which is mainly driven by the steam generated by biomass combustion to realize power generation. The key point of this power generation technology is to treat the biomass raw materials in advance, take certain anti-corrosion measures for the combustion boiler to ensure the adaptability of raw materials, and monitor and control the combustion efficiency and steam engine working efficiency in real time. There is also a power generation technology with broad development prospects, that is, the use of waste combustion for power generation. This power generation technology is to realize the gasification, melting and incineration of waste under high temperature. It can not only realize the power generation effect by using combustion energy, but also realize the complete incineration effect of waste, with high cleanliness and strong environmental protection performance.
