A11 Development of a Waste Incineration and Power Generation System

Wastes are defined as a new energy and desired to utilize an energy source beneficially. The authors pay attention to better utilization of wastes, which is a method to convert wastes into energy, and present a waste incineration and power generation system constructed by an incinerator and a Stirling engine generator. The incinerator has a maximum incineration capacity of 49kg/h and is cooled by circulating water in the side walls in order to enable a long life and supply heat by a hot water or air flow. The Stirling engine generator is installed in a secondary combustion space of the incinerator and heated by combustion gas and an auxiliary kerosene burner. In order to demonstrate the power generation and the heat supply, a test using woody biomass as fuel is carried out at a greenhouse tomato plantation in Hokkaido. From the test results, the system showed the electric output of 3.2kW and heat supply of 47kW, and practicability of the waste incineration and power generation system is verified.
