Micro Combined Heat and Power to Provide Heat and Electrical Power using Biomass and Gamma-type Stirling Engine

With consideration of the biomass energy potential, a Gamma type Stirling engine with 220 cc swept volume and 580 cc total volume was designed, optimized and manufactured. The engine was tested with helium. Working characteristics of the engine were obtained within the range of heat source temperatu...
