PURPOSE:To prevent the corrosion of a heat source and place spray water close to the source by facing a spray water jet part with an opening provided on the front face of an evaporating case and lowering the case after facing the bottom face thereof with a water supply system. CONSTITUTION:An evaporating case 20 is made of a material with a high heat conductivity and a high corrosion resistance and contacted close to a heat-exchanger. The bottom face 20a is inclined toward a water receiving dish 17. A convection feed air inflow port 21 is formed by entirely opening the front face 20d of the case 20, and a spray nozzle 15 is faced therewith. Thereby, when the air pressure-fed by the a rotating turbo fan 11 is jetted thrugh a spray nozzle 15, the water in the dish 17 is sucked and jetted as atomized water drops into the case 20. At the start of combustion, the temperature of the heat-exchanger is too low to make gasification. Therefore, spray water is collected at the bottom but drained to a water supply system 17 by the inclined bottom plate. The corrosion of a heat source is thus prevented. |
