Abstract:
An exhaust duct has a riser duct section which is connected to an exhaust port having such an inlet port at a lower portion of the riser duct section as is connected to an exhaust port for the combustion gas, the exhaust port being opened at a lower portion of the combustion box. The riser duct section extends upward along an external surface of the combustion box. Suppose that a direction normal to the external surface of the combustion box is defined as a front-to-back direction, and a horizontal direction perpendicular to the front-to-back direction is defined as a lateral direction, then the riser duct section is formed into a flat shape having a smaller dimension in the front-to-back direction than the dimension in the lateral direction. Fluctuations in width between front-side and back-side plate parts of the riser duct section are devised to be restrained, and increase in size can be avoided. The riser duct section has a rail inside the riser duct section, the rail being elongated in the vertical direction and connecting together the front-side and the back-side plate parts.

Claim (Index 4):
The exhaust duct according to  claim 1 , wherein a plurality of rails are disposed, and a lateral dimension or a vertical dimension of at least one of the rails is varied in the vertical dimension or vertical dimension of the remaining rails.
