PROBLEM TO BE SOLVED: To achieve a highly efficient heat exchange the same in the full combustion state even in the partial combustion state by arranging a link part as an area between a main heat exchanger and a heat exchanger for recovering latent heat to separate space areas facing individual combustion surfaces of burner with a partition member. SOLUTION: This combustion apparatus is equipped with a burner 2 with a plurality of combustion surfaces and a heat exchanger 4 for recovering latent heat which is arranged on the exhaust side of a main heat exchanger 3. In this case, a partition part 18 is provided at a link part 15 between the main heat exchanger 3 and the heat exchanger 4 for recovering latent heat to separate space areas facing individual combustion surfaces of the burner 2. In the partial combustion state wherein combustion occurs only on combustion surface A or on the combustion surface A and the combustion surface B of the burner 2, exhaust generated on the combustion surface involved and feed air passing trough the combustion surface not involved flow into the link part 15. The partition member 18 prevents the exhaust and the feed air from mixing with each other to block drop in the heat exchange efficiency of the heat exchanger 4 for recovering latent heat thereby providing a combustion apparatus with a high heat efficiency. |
