Description
Technical field
The utility model relates to a kind of gas flame heating furnace such as various tunnel caves, trolley type heating furnace, chamber-type heating furnace that metallurgy, machinery, chemical industry, oil etc. have the high-temperature fuel gas firing equipment that can be applicable to, and particularly relates to a kind of heat-accumulating burner of gas flame heating furnace.
Background technology
Current, the energy utilization rate of China is low, energy waste is large, and wherein the high-temperature fuel gas firing equipment (flame furnace) of the industries such as metallurgy, machinery, chemical industry, oil embodies particularly outstanding as the big power consumer.Therefore, saving energy and reduce the cost, increase economic efficiency, adopt effective new technology, is the only way which must be passed of hot-working flame furnace.Along with novel heat storage---the appearance of ceramic bead and ceramic honeycomb body, make the ancient regenerative combustion technology of script shine unlimited powerful vitality, then develop into a kind of being called as the combustion technology of " HTAC (HTAC) ", it is efficient burning and Mist heat recovering greatly and reduce the technology such as NO discharging and organically combine, and has realized the dual purpose of the energy-conservation and limit reduction NO discharge capacity of the limit.Heat-accumulating burner generally by a pair of burner, a pair of heat storage, switch to changing valve and related Control System forms.A burner and one group of heat storage are one group, and two groups are used by turns, combustion air can be preheating to be lower than about furnace temperature～250 ℃, exhaust gas temperature≤200 ℃, energy-saving effect is obvious.Regenerative combustion technology has great promotional value.
At present, the heat-accumulating burner (combustion technology) of developing both at home and abroad, there are two types: (1) burner formula Regenerative Combustion Technology, its structure is that each burner carries a heat storage tank, and heat storage is arranged in the heat storage tank, the ejiction opening of burner and the inlet scoop of burner share, the combustion product running orbit of burner ejection is identical with the running orbit of off-gas recovery, is opposite direction, so the ejiction opening of burner also is the recovery mouth of flue gas.(2) accumulation of heat ditch formula Regenerative Combustion Technology, this technology is that heat storage is arranged in the body of heater, generally is the below that is arranged in body of heater two sides, in body of heater, form two burning ditches, during reversing combustion, the burning of two sides, one side of body of heater, a side accumulation of heat, after the commutation, former accumulation of heat side burning, combustion side accumulation of heat.So its air running orbit is also identical with the flue gas running orbit, be opposite direction, so the ejiction opening of burning also is the recovery mouth of flue gas.
The flame of heat storage type combustion generally adopts diffuse type flame, and namely fuel mixes in stove with air, and it is larger that flame is sprawled face, and does not have rigidity.Combustion product in the stove and the flow direction of flue gas produce the dead angle easily in stove, cause the lower defective of temperature homogeneity in the stove.Therefore regenerative combustion technology is promoted and brought certain limitation.As: special steel has strict temperature uniformity requirement at heating process, general control≤± 10 ℃ in, otherwise in heating process, be easy to produce waste product.
