The first portion 11 and the second portion 12 can be communicated with each other through an intermediate manifold 13. As shown in FIG. 2, a plurality of heater pipes 4 are divided into four groups, and each group is assembled as a set. The heater pipes 4 belonging to each group are separated by a plurality of fins 14 spaced apart from each other.
The part 11 and the second part 12 are connected. Finn 14
As shown in FIG.
It is formed in such a shape as to surround approximately half of the portion 11 and the entire circumference of the second portion 12 . As shown in FIG. 3, the first portion 11 of the heater pipe 4 may be surrounded entirely.

ガスを効率よく加熱できる。 As is clear from the above, in this invention, the first part of the heater pipe on the flame side and the second part behind it
Since the parts are connected by fins, the radiant heat of the flame received by the first part is transmitted to the second part by the fins. Further, the radiant heat of the flame received by the fins is transmitted to the opposite side of the heater pipe from the flame side, that is, to the rear surface, and together with the convection heat of the combustion gas, uniformly heats the heater pipe. Heater pipe 1
The installation of the fins connecting the part and the second part increases the heat receiving area for the radiant heat from the flame and the convection heat of the combustion gas, and also increases the heat transfer area. The back side can also be heated in the same way as the front side. As a result, the entire circumferential surface of the heater pipe can be heated uniformly, and the working gas inside the heater pipe can be efficiently heated.
