Abstract: |
Micro Thermophotovoltaic (MTPV) system is a new micro power Mechatronic system that converts thermal energy to electrical energy using thermal radiation property of material. Micro combustion chamber is the core part of this MTPV power system. When fuel is burnt in the micro combustion chamber, thermal energy is produced and then transferred to photovoltaic element through photons radiated by external wall of the micro combustor, and thus electrical energy can be exported. The temperature of external wall of micro combustor is the key standard measuring the conversion efficiency. By the test to analyze and describe the change of external wall temperature and radiation performance of tubular micro combustor when the factors including porosity, mixture ratio of CH4/O2, mixed gas flow and wall thickness of micro combustor are changed, the references are obtained for practical application of micro combustor and micro thermophotovoltaic system.
