Filed: 1991-07-11
Abstract: PURPOSE: To retard the deposition of carbon at the mixing point of fresh fuel gas and recirculation gas by conducting heat exchange of recirculation gas and a reforming material, and make the sealing at high temperature unnecessary. CONSTITUTION: High temperature used fuel gas from a channel 46 is made almost 1000 deg.C in a reforming chamber 54, and reaches a channel 46'. The used fuel gas flows downward from the channel 46', comes in contact with the outside of a mixing/diffusion chamber 54, and furthermore loses heat. The heat is transmitted to a reformable fuel mixture 51 as it approaches to a reforming chamber 56. The fuel mixture 51 flows upward toward the reforming chamber 56 and a power generating chamber 22. The temperature of the used fuel gas decreased from about 1000 deg.C at the inlet of the channel 46' to sufficiently low temperature as it approaches to a nozzle 50, and therefore, fresh fuel in a mixing chamber 52 becomes 400 deg.C or lower.
