PURPOSE:To increase the heat exchanging efficiency of a heat exchanger, by positioning a mixing pipe so that the extended center line of combustion flames runs along the arbitral section crossing with the longitudinal center line of a combustion chamber, and by displacing the pipe biasedly close to the outside direction of a combustion chamber by a suitable distance. CONSTITUTION:A mixing pipe 20 is positioned so that the extended center line B of combustion flames runs along the section C crossing at right angles with the longitudinal center line A extended to the discharge side of a combustion chamber 3, passing through its center part, and the pipe 20 is fitted to the combustion chamber eccentrically slipped off to the outer side of a combustion chamber 3 as much as a suitable distance D to the longitudinal center line A. The combustion gas is sprayed to the vicinity of the crossing point of the extended center line B of combustion flames and an inside wall 2a, and part of the gas flows to the direction of an arrow sign F along the surface 2a' of an inside wall, coming down to the circulation flow inlet port 16, being forcibly sucked into the mixing pipe 20, and is momentarily mixed with the mixed mist of kerosene particles and fresh air. The combustion gas dispersed to the direction of an arrow sign E flows upwardly, spirally circulating along the circumferential direction of the surface 2a' of an inside wall, and is discharged to the outside, exchanging heat with the water in a water chamber 2c. By this method, the heat exchanging efficiency of a heat exchanger can be increased.
