WASTE HEAT UTILIZATION METHOD AND MODEL CONSTRUCTION OF BIOGAS GENERATOR SETS BASED ON TWO-STAGE CORRECTION OF THERMOELECTRIC POWER GENERATION
To make full use of biogas energy and improve the energy utilization rate of biogas power generation,this paper proposes to use thermoelectric generator to recover the waste heat of biogas generator sets.The simulation model of waste heat recovery and utilization of biogas generator sets based on two-stage correction of thermoelectric power generation is constructed by Matlab/Simulink,and the model is verified by measured data.The results show that the mean absolute percentage error(MAPE)of the two-stage modified thermoelectric generation model is 0.045%,and the second correction is 0.167% lower than the first correction mean absolute percentage error(MAPE).After adding the thermoelectric generator,the energy utilization rate of the biogas power generation system can be increased by 8.59 percentages poimt,and the waste heat utilization efficiency can be increased by 15.53 percentages poimt.
