(hereinafter abbreviated as a heat exchanger), the inside of which forms the combustion chamber 5 of the combustor 3. Further, the heat exchanger 4 has a gap 6 between its upper and lower ends with the upper plate IA and the lower plate IB of the can body 1, respectively.
．． 7, and the outer peripheral side is arranged with a gap 8 between it and the side plate IC of the can body 1. A combustion gas passage communicating with the combustion gas discharge port 2 is formed in each gap 6, 7.8. A partition plate 9 is provided at the upper end of the heat exchanger 4 and partitions the gap 6 and the combustion chamber 5.

で、該仕切板９の温度が低下する。Next, to explain the operation of the liquid heater of the present invention, the liquid to be heated is caused to flow in the heat exchanger 4, and the combustor 3 is heated in the combustion chamber 5.
When combustion occurs in the combustion chamber, the high-temperature combustion gas flows in the direction of the arrow in the figure, heating the liquid in the heat exchanger 4 and exchanging heat with the liquid in the exchanger 4 forming the combustion scum passage. Since the temperature of the upper plate of the can body 1 is lowered as it approaches the combustion gas outlet 2, the temperature of the combustion gas flowing through the can body 1 is also kept lower. Furthermore, when the low-temperature combustion scum flows through the gap 6, it cools the partition plate 9 located at the high temperature, so the temperature of the partition plate 9 decreases.
