Title:
GAS WATER HEATER
Document Type and Number:
WIPO Patent Application WO/2021/063049
Kind Code:
A1
Abstract:
The present disclosure discloses a gas water heater, wherein, including a gas mixing device, a combustion chamber, a heat exchange chamber and a condensate collector sequentially communicated; the inlet end of the gas mixing device is respectively communicated with an air supply device and a gas supply device, the combustible gas and combustion air form the mixed gas in the gas mixing device; a catalytic combustor is provided in the combustion chamber, the mixed gas is oxidized and combusted in the catalytic combustor to produce high-temperature flue gas; a heat exchanger is provided in the heat exchange chamber, the high-temperature flue gas heats the water in the heat exchanger to produce hot water; the outlet end of the condensate collector is communicated with a smoke exhaust device, the low-temperature flue gas is discharged from the smoke exhaust device, and the produced condensate water falls in the condensate collector. The gas water heater of the present disclosure catalytically oxidizes the gas, through the action of the catalytic combustor, the gas can be effectively and fully combusted, the temperature during combustion is reduced, and ultimately the formation of nitrogen oxides and carbon monoxide is inhibited.
