Abstract
Along the furnace wall the high efficiency heat accumulating industrial furnace has one pair of heat accumulators with heat accumulating body in the middle part, combustion supporting air and smoke exhausting channel in the low part, open mouthed fuel mixing burner in the upper part and at least one pair of fuel oil or gas nozzles arranged outside the burner. Fuel oil or gas burns in the burner to form fire screen over the burner. There is outside change mechanism to make the two heat accumulators preheat air and make fire screen or accumulate heat and exhaust smoke alternately.
Description
The invention belongs to afterheat recovery type industrial furnace, particularly cell-type and car tunnel furnace.
The cell-type of prior art and tunnel type industrial furnace, gather in body of heater two outsides combustion gas or oil burner, the nearly furnace wall lower inside in burner hearth is provided with exhaust smoke hole, and exhaust smoke hole connects smokejack.Its duty is a both sides burner jet flames in burner hearth simultaneously, and flue gas is discharged burner hearth by the exhaust smoke hole of nearly furnace wall inboard.The shortcoming that exists at first is that flame combustion is inhomogeneous, and the Temperature Distribution in stove is also inhomogeneous, and the burner hearth each point temperature difference is bigger; Next be a large amount of calory burning along with flue gas is discharged, cause the waste of the energy.
The objective of the invention is to propose a kind of high-efficiency heat-accumulating industrial furnace technical scheme, utilize smoke pre-heating with energy savings, and flame is evenly burnt, temperature evenly distributes in stove.
High-efficiency heat-accumulating industrial furnace of the present invention, comprise body of heater, combustion air pipeline, combustion gas or fuel passage, along the furnace wall direction a pair of heat storage tank is set at least at body of heater two side lower parts, the heat storage tank bottom is combustion air passage/discharge flue, heat storage is filled at the heat storage tank middle part, heat storage tank top is the fuel mix burning groove of open top formula, two outer side edges of burning groove are arranged at least one pair of combustion gas or fuel nozzle are set, the mixed combustion in burning groove of combustion gas or fuel oil and combustion air, above the burning notch along furnace wall longitudinally the furnace superintendent direction form the burning fire screen of face formula; Combustion air passage/the discharge flue of both sides and combustion gas or the external changement of oil burner pipeline make heat storage tank alternately preheated air or the accumulation of heat smoke evacuation respectively of both sides, and the fire curtain that both sides are alternately produced flow to other side.When adopting combustion gas to do fuel, can along the furnace wall direction two pairs of heat storage tanks be set at body of heater two side lower parts, the mixed combustion groove on two heat storage tank tops of body of heater homonymy is shared burning groove, the blast tube that the gas nozzle that is provided with is arranged on a pair of heat storage tank bottom of the body of heater both sides that are placed in is arranged in burning groove two outsides on heat storage tank top, and another bottom to the heat storage tank of the body of heater both sides that are placed in is the combustion air passage; Combustion air passage and blast tube also are discharge flue in the accumulation of heat cycle.The heat storage that fill at heat storage tank of the present invention middle part is spherical or cellular, heat storage support in its underpart by heat-resistant net and with the gas passage of heat storage tank bottom at interval, the gas communication gap is arranged in heat-resistant net and heat storage.Industrial furnace of the present invention, the type of furnace can be bell furnaces; The type of furnace also can be a bogie furnace; The type of furnace also can be a walking beam furnace; The type of furnace can also be that continous way is rolled end formula stove or steel-pushing type stove.
The present invention has outstanding substantive distinguishing features and is to be provided with heat storage tank in body of heater inside, can form the fire curtain of face formula; The external side of industrial furnace of the present invention does not have the burner of prior art, the exhaust smoke hole that does not yet set up in the stove; The combustion air passage of body of heater of the present invention both sides and combustion gas or the external exchange system of fuel passage, accumulation of heat and warm-up combustion-supporting air and combustion gas work hocket.
Obvious improvement of the present invention is that at first the heat that fuel combustion produces is fully utilized in the preheating of air and combustion gas through heat storage tank, and the flue-gas temperature of discharging through regenerator can be reduced to below 150 ℃, significantly energy savings; Secondly, the burning groove of both sides alternately produces the fire curtain of face formula in stove, and fire curtain and alternating current make uniformity of temperature profile in the stove to other side.
