Abstract
Micro scale pelletized RDF (Refuse derived fuel) gasifier using the superheated steam as gasifying agent was developed and the feasibility of the syngas as fuel for micro co-generation was verified. The thermal cracking experiment of wood was conducted at 500 to 700 degrees C. Syngas was analyzed and char and tars content were determined and analyzed. Moisture and tar in syngas were removed by a cooling device kept at 0 degree C. The calorific value of syngas was about 14 MJ, and was about 1/3 of town gas. Then, refining gas was supplied as fuel of a micro gas engine of 1 kW of outputs. And the production of electricity using the micro gas engine was measured. It experimented by changing the mixture ratio of syngas and town gas. As a result, it turned out that the mixture ratio of syngas is 13% possible for rated operation. Moreover, it compared with the simulation result. Furthermore, it investigated theoretically also about the feasibility as fuel for molten carbonate fuel cell.
