In order to alleviate the current tense energy use situation and reduce the destructive impact of fossil fuel energy on the environment,many regions have started to build straw power plants,which generate electricity through straw combustion and replace fossil fuel energy with straw.Based on this,in order to ensure the economic benefits and income of straw power plant fuel power generation,how to determine the fuel collection radius of the power plant within an appropriate range is described,clarify the relationship between the fuel collection radius of the straw power plant and the installed scale,and ensure the stability of straw fuel power generation.
