Gas fuel heating device

The utility model discloses a gas fuel heating device, comprises a base, be provided with the frame on the base, its characterized in that, be provided with in the frame and take the interbedded burning furnace of the firing thorax of water jacket, fire that the burning furnace thorax is external to have a combustor, be equipped with the high temperature flue gas entry linkage of high temperature exhanst gas outlet and heat exchanger in firing the burning furnace thorax, fire the high temperature flue gas that produces in the burning furnace thorax pass through the high temperature exhanst gas outlet via high temperature flue gas entry gets into the heat exchanger, and the low temperature flue gas that the high temperature flue gas formed behind the heat exchanger is discharged through the connecting pipe of discharging fume from the heat exchanger exhaust port, low warm water is got into the heat exchanger by the water inlet in, the warp is in carry out the heat supply from heat exchanger delivery port output use after being the high -temperature water by the heating in the heat exchanger, this heating device is still including the controller. Owing to adopted above -mentioned scheme, can make gas fuel heating device's volume reduce, the weight loss, manufacturing cost reduces, and the thermal efficiency more high energy is saved manyly, makes things convenient for heating device's transportation, installation and field maintemance.
