PURPOSE: To provide a combustion equipment, in which the combustion temperature of fuel in a combustion furnace is elevated while damage of a piping opened into a fuel layer due to heat can be inhibited.

CONSTITUTION: The combustion equipment has a combustion furnace 2 formed in an inverted truncated cone shape by winding a tube body 4, a water supply section 6 pressing and supplying air and water into the tube body 4, a nozzle 4b which mixes steam generated during a time when water is passed in the tube body 4 and air spraying the mixture into a fuel layer 7 during combustion, and a grate 8 covering the upper section of the nozzle 4b in the fuel layer 7. Accordingly, steam and air are mixed and sprayed, thus forming an oxyhydrogen flame, then conducting combustion having excellent efficiency at a high temperature.
