In the case where exhaust gas from multiple combustors such as
The exhaust gas in the collecting pipe was collected into a collecting pipe D, and the intake port E of the fan was connected to the collecting pipe to discharge the exhaust gas in the collecting pipe.

ものではなかつた。(Problems to be Solved by the Invention) However, in this case, the balance and rectification of the exhaust gas from each combustor are greatly affected by the position of the intake port E of the fan C. In other words, the displacement of the combustor closer to the intake port E is increased. If each combustor has a different combustion capacity, it is difficult to match the positions of the inlet E and the exhaust pipe F in order to balance the displacement. Furthermore, the flow of exhaust gas within the combustor was uneven due to the position of the opening of the exhaust pipe F into the combustor, resulting in poor efficiency.

口の中央部に導いてある。(Means for solving the problem) In order to achieve this objective, the present invention has the following configuration. In other words, when exhaust gas from multiple combustors is discharged by a single fan, the inlet of the fan is opened directly above one combustor, and the exhaust duct from the other combustor is connected to the center of the inlet of the fan. I was led to the department.

is opened. 6 is a fan, its intake port 7
is opened on the exhaust manifold 3 directly above the combustor 2. Reference numeral 8 denotes a cross-sectional exhaust duct having a collar 11 at one end and attaching the other end to the inner wall of the exhaust manifold 3 by crossing the center of the inlet 7 to partition the exhaust manifold 3 and directing the exhaust from the combustor 1. The mouth 5 and the central part of the suction port 7 are communicated with each other. That is, the central portion 7a of the intake port 7 communicates with the combustor 2. 9,1

The exhaust gas from the distant combustor is strongly sucked in, which eliminates the problem of insufficient exhaust gas, and allows the exhaust amount to be easily controlled by setting the passage area of the exhaust duct according to the capacity. In addition, the exhaust gas from the combustor directly below the inlet is dispersed around the inlet and taken in, so the flow of the exhaust is not biased and a uniform flow occurs in the heat exchanger, achieving high efficiency. .
