Background technology
Fuel gas hot-blast stove adopts fuel directly to burn exactly, forms hot blast through high purified treatment, and the dry or baking with material Direct Contact Heating.The high-temperature combustion gas that fuel obtains after combustion reaction further contacts with outside air, directly enters hothouse or bakery after being mixed into a certain temperature, contact with the material that is dried, and heating, transpiring moisture, thus obtain dry products.
Existing gas hot-air boiler mechanism is unreasonable, and operating cost is high, and the low leaving air temp of efficiency is unstable, uses very inconvenient and maintenance rate is high.
Summary of the invention
The utility model is unreasonable in order to solve gas hot-air boiler mechanism, and operating cost is high, and the problem that the low leaving air temp of efficiency is unstable and maintenance rate is high provides a kind of full-automatic direct-type gas hot-air heating furnace especially.
The utility model is taked following technical scheme: a kind of full-automatic direct-type gas hot-air heating furnace, comprise combustion chamber and flue gas and air mixing chamber, combustion chamber is connected with burner by burner interface, one end, combustion chamber is provided with high-temperature flue gas outlet, high-temperature flue gas outlet is communicated with air mixing chamber with flue gas, outside, combustion chamber is provided with circulating flue gas pipeline, and circulating flue gas device for cleaning pipeline is crossed cold air inlet and is communicated with air mixing chamber with flue gas, and flue gas and air mixing chamber opposite side are provided with hot air outlet; Whole equipment outside is provided with outer insulation.
Described combustion chamber comprises the fire-resistant inner bag of heat-insulation layer, and the fire-resistant inner bag of heat-insulation layer outside is provided with furnace internal-lining.
Described flue gas and air mixing chamber comprise outer courage, and outer courage inner side is provided with mixing chamber inner thermal insulating layer, and outer courage outside is provided with furnace outside-lining, and the hot air outlet place of flue gas and air mixing chamber is provided with rear heat-insulation layer.
After natural gas via burner is lighted, fully burning in combustion chamber, the high-temperature flue gas that burning produces, from combustor exit, out enters flue gas and air mixing chamber, with the Cryogenic air from ventilation blower, carries out hybrid cooling in flue gas and air mixing chamber.Cold air after cooling is entered in the system that needs heating by hot-blast outlet.
Cold air, under the effect of ventilation blower, tangentially enters in furnace internal-lining periphery along the periphery of flue, travels forward around the outer wall rotation of flue, evenly enters in flue gas and air mixing chamber, carries out flue-gas temperature adjusting.Heat of mixing air through regulating, by hot air outlet, enters in follow-up drying equipment and coal mine.
Compared with prior art, the utlity model has following beneficial effect:
Combustion furnace and mixing chamber are structure as a whole, and flexible arrangement is applicable to maximization future development.
Adopt flue gas and air hybrid technology, the temperature that makes full use of the useless flue gas participation of afterbody flue gas regulates, and has saved a large amount of energy on the one hand, improves again on the other hand the thermal efficiency.
Adopting totally-enclosed operation under positive pressure mode, is malleation in flue, and structure is compacter, good looking appearance, and floor space is little.
