PURPOSE:To heighten the thermal efficiency, by blowing combustion gas into liquid and mixing them with each other in a tube to perform thorough heat exchange. CONSTITUTION:A gas burner 3 is mounted downward at the top of a combustion chamber 2. The lower part of the gas burner 3 communicates with a combustion gas generating tube 4 extending horizontally and having combustion gas blow- off holes 5. The combustion gas generating tube 4 is located in the liquid in a heat exchange vessel 6. A bubble diffusing plate 7 projects from the tube 4. Another pipe 8 is coupled to the upper part of the heat exchange vessel 6 so that the exhaust gas and the liquid flow down into a liquid vessel 11. At that time, the liquid and the exhaust gas are thoroughly mixed with each other by a resistor 9 and a spiral blade 10. The exhaust gas separated from the liquid in the liquid vessel 11 is discharged from an exhaust cylinder 12. |
