Abstract

The invention relates to a fuel gas heating furnace which comprises a main heat exchanger and a secondary heat exchanger, a water tank, a water tube, a temperature sensor, a central processing unit, a speed-variable fan whose rotation speed is controlled by the central processing unit, and a fuel gas rate valve whose output power is controlled by the central processing unit. The invention can fully condense the vapor and effectively recycle the heat of vapor in the discharged smoke.

Description

technical field [0001] The invention relates to a gas heating furnace. Background technique [0002] At present, most heating and hot water dual-purpose heating stoves use gas to work. During the use of ordinary gas dual-purpose heating stoves, about 10% of the heat is discharged with the flue gas, which causes a waste of energy. Because gas produces a large amount of water vapor when it is burned, 1 cubic meter of natural gas can produce 1.6 kilograms of water when it is completely burned. Therefore, the existing dual-purpose heating furnace mostly adopts a secondary heat exchange structure to condense the water vapor in the flue gas after the combustion of the gas. In this way, the heat in the flue gas after combustion of the gas can be reused to a certain extent. [0003] The application number is 03272510.8, and the Chinese utility model patent application titled "new gas heating / hot water dual-purpose boiler" discloses a dual-purpose gas heating boiler with secondary...
