摘要： A secondary heat exchanger B for recovering latent heat from combustion gas includes water tubes 5 each of which is so inclined that a first end 50a is positioned lower than a second end 50b. Therefore, in draining water from each of the water tubes 5, water can be caused to flow smoothly into a water-inflow and hot-water-outflow header 6A connected to the first ends 50a. The secondary heat exchanger B includes a casing 7 which includes an upper wall 70a and a bottom wall 70b which are so inclined that the inner surfaces thereof extend generally in parallel with the water tubes 5, and the upper and the lower gaps 79a and 79b have constant widths s2 and s3. Therefore, the amount of heat recovery from the combustion gas passing through the gaps 79a and 79b can be increased.

摘要翻译： 用于从燃烧气体回收潜热的二次热交换器B包括水管5，每个水管5倾斜使得第一端部50a位于比第二端部50b低的位置。 因此，在从每个水管5排出水时，可以使水顺利地流入连接到第一端部50a的流入水和热水流出集管6A。 二次热交换器B包括壳体7，壳体7包括上壁70a和底壁70b，所述上壁70a和底壁70b倾斜，使得其内表面大致与水管5平行地延伸，并且上部和下部间隙79a 和79b具有恒定的宽度s 2和s 3。 因此，可以增加通过间隙79a和79b的燃烧气体的热量回收量。

摘要： A heat exchanger A1 includes: a case 2 surrounding a heat transfer tube 4; and a guide member 5 for guiding heating gas entering the case 2 through an intake vent 21 to a first space region 24A and then to a second space region 24B, the guide member 5, together with a wall portion 20b, defining therebetween a gap 25b in communication with a gap 25a between the wall portion 20b and the heat transfer tube 4 for allowing part of the heating gas having been guided to the first space region 24A to proceed into the second space region 24B through the gaps 25a and 25b. This arrangement performs efficient heat recovery from the heating gas by effectively utilizing the entire heat transfer tube 4 while alleviating a problem that the case 2 is partially heated to elevated temperatures.
