[0002] Agricultural waste, that is, agricultural waste. It refers to organic materials discarded during the entire agricultural production process. Usually, what we call agricultural waste mainly refers to crop straw and livestock and poultry manure. Biogas combustion power generation is a biogas utilization technology that has emerged with the continuous development of large-scale biogas pool construction and comprehensive utilization of biogas. It uses the biogas produced by anaerobic fermentation treatment on the engine and is equipped with a comprehensive power generation device to generate electricity and heat energy. Biogas power generation has the characteristics of efficiency, energy saving, safety and environmental protection. It is a widely distributed and inexpensive distributed energy. Biogas combustion power generation produced by garbage fermentation is an emerging power generation technology. Biogas needs to be purified before use.
