<p>PROBLEM TO BE SOLVED: To provide a combustion device in which gaseous fuel is ignited in liquid to efficiently heat liquid. SOLUTION: Gaseous fuel and oxygen are mixed by a mixer 8 and the mixed fuel is supplied to a combustion container 9 through a fine gaseous bubble generating device 11. Water is supplied into the combustion container 9. A sound pressure is applied by a sound wave generator 12 within the combustion container 9 in which fine gas bubbles of the mixture gas are present in water. With such an arrangement as above, a spherical shock wave is imploded within the fine gaseous bubbles, the gaseous bubbles are ignited so as to heat water in the container 9.</p> |
