PURPOSE: To remove a partitioning damper from a multiple combustor, by connecting each exhaust-gas flow path to the outlet flues of a plurality of combustors, respectively, and by joining each flow of exhaust gas to a flue by opening the outlet of each exhaust-gas flow path to a negative pressure part in the neighborhood of a stack.
CONSTITUTION: Three exhaust-gas flow paths 7a, 7b, and 7c are formed in a common flue 3 by dividig it into three parts by partitioning boards 5, 5, and one end of each exhaust-gas flow path 7a, 7b, and 7c is connected to each outlet flue 6a, 6b, and 6c. The other end of each exhaust-gas flow path is respectively opened to the negative pressure part of a common flue 3 to be joined in one, that is in the neighborhood of a stack 4. The exhaust gas flowing out of each combustor 1a, 1b, and 1c flows to a joining part, passing through each outlet flue, since the pressure in the outlet flue is high, and that in the joining part is made to be of the negative pressure. The exhaust gas is exhausted from the stack 4 to the open air. With such as arrangement, a partitioning damper is made unnecessary, so that the manufacturing cost of a flue can be lowered, in addition, the reliability of an apparatus can be enhanced.
