Abstract
The utility model provides a micro gas turbine power generation system with a wave rotor top regenerative cycle. The micro gas turbine power generation system with the wave rotor top regenerative cycle comprises a gas compressor, a wave rotor, a turbine, a heat regenerator, a combustor chamber and a generator. Exhausted air of the turbine enters the heat regenerator and waste heat of the exhausted air is recycled. Fuel I and compressed air which is heated up through the heat regenerator are mixed to form fuel gas and the fuel gas enters a solid oxide fuel cell (SOFC), waste gas of the SOFC enters the combustor chamber and is mixed with fuel II to burn. The SOFC is introduced into the micro gas turbine power generation system and improves generated output of the overall system. High-temperature exhaust gas of the SOFC is fully utilized by the micro gas turbine power generation system and then enters the turbine to continue inflating and acting, and therefore efficiency of the overall system is improved.
