Abstract

The working principle of the micro-CHP based on biomass direct-fired Stirling engine and the thermal energy conversion process of the biomass direct-fired fuels were analyzed. On the basis of analysis, a 1kW β-type Stirling generator was designed and constructed for lab tests. Then, experiments were carried out to evaluate the effectiveness of the prototype. Through the analysis of experimental data and simulation, the change law of charge voltage, charge current with the engine speed and pressure, as well as the relation of heat and electricity, the power generation efficiency and the overall efficiency of the thermoelectric in the working process was obtained. The results showed that biomass energy use efficiency will be improved through the use of micro-CHP based on biomass direct-fired Stirling engine.
