PURPOSE:To enhance reliability by separating oxidant gas and fuel gas from each other by a partition wall, for oxidizing combustion. CONSTITUTION:Fuel gas FG and oxidant gas OG which are heated by a heat exchanger 3 are supplied to a stack 1 through an oxidant gas inlet 9 and a fuel gas inlet 10. OG and FG introducing pipes 17, 18 are disposed in the upper portion of the stack 1. OG and FG are exhausted into oxidant gas exhaust chambers 30 and fuel gas exhaust chambers 31 partitioned by an upper pat 13 and an intermediate pat 8. These exhaust gases enter into a combustion chamber 2 via a first exhaust gas passage 5 formed on an adiabatic wall 4, followed by mixing for combustion, to be cooled by the exchanger 3 and discharged through an exhaust gas outlet 12. A heat insulating member is housed inside a heat insulating container 7 so that a temperature of a metal member cannot be increased. However, because the wall 4 is heated on both the sides thereof, a heat resistant metal is disposed in the center of the wall. For the purpose of prevention of back fire, porous ceramic is used for the passage 5. Heat resistant brick is used for a partition wall 6. Consequently, it is possible to enhance reliability and obtain excellent stability. |
