Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, invention comprises heat insulation-type furnace wall 1, thermal capacitance chamber 2 and 8, thin-walled thermal capacitance device 3 and 7, metal hose 4 and 6, air exhaust gases passes switch valve 5.Furnace wall 1 is embedded with water cooling tube.The thermal capacitance chamber is generally being provided with.Thin-walled thermal capacitance device 3 and 7 places respectively in thermal capacitance chamber 2 and the thermal capacitance chamber 8, thermal capacitance device 3 and 7 and a side and the furnace wall face of thermal capacitance chamber 2 and 8 tangent, thermal capacitance chamber 2 and 8 all leave 1 gas compartment away from the furnace wall side.Furnace wall 1 connects in the flange mode mutually with thermal capacitance chamber 2 and thermal capacitance chamber 8.Thermal capacitance chamber 2 connects in the flange mode by metal hose 4 and air exhaust gases passes switch valve 5, and thermal capacitance chamber 8 connects in the flange mode by metal hose 6 and air exhaust gases passes switch valve 5.Metal hose 4 and 6 can reduce the destruction of burner hearth 1 elevated temperature heat stress to whole device.The weight of thin-walled thermal capacitance device 3 by thermal capacitance chamber 2 together with the weight transmitting of thermal capacitance chamber 2 to the furnace wall 1, the weight of thin-walled thermal capacitance device 7 also is passed to furnace wall 1 by thermal capacitance chamber 8 together with the weight of thermal capacitance chamber 8.Thermal capacitance chamber 2, thin-walled thermal capacitance device 3 and metal hose 4 and thermal capacitance chamber 8, thin-walled thermal capacitance device 7 and metal hose 6 to be connected arrangement identical, two covers connect can be along the furnace wall 1 centralized arrangement, also can be along the furnace wall 1 dispersed placement.
Thin-walled thermal capacitance device 3 and 7 is by stacked the forming of numerous thin-walled thermal capacitance sheets.The thermal capacitance sheet forms by firing based on the earth of alumina composition, has the honeycomb hole gas channel, between the passage between wall thickness 0.4～1mm, the length of side 2.5～3.0mm in the passage, specific area surpasses 800m 2/ m 3When the thermal capacitance sheet is stacked, between the thermal capacitance sheet heat insulation-type binding agent, numerous mutual UNICOMs of thermal capacitance sheet honeycomb hole passage, the drag losses when reducing air flow stream to greatest extent and crossing honeycomb channel.When air or flue gas flow through thin-walled thermal capacitance sheet honeycomb channel, gas and vias inner walls in the face of stream and radiation heat transfer thermal resistance much larger than the inner thermal conduction resistance of thermal capacitance sheet (it is far away little of 1 to finish your criterion numeral of room), so that each thermal capacitance sheet changes in time and changes with the temperature of uniformity all the time.
When air flow through thin-walled thermal capacitance device 3, flue gas flow through thin-walled thermal capacitance device 7.High-temperature flue gas is discharged via thermal capacitance chamber 8 under the exhaust opening suction function of air exhaust gases passes switch valve 5.In the thermal capacitance chamber 8 li, high-temperature flue gas is stored in 7 li of thin-walled thermal capacitance devices rapidly with its sensible heat that carries, and temperature reduces (exceeding about 100 ℃ of environment temperatures) significantly and finally is discharged into atmosphere when treating that flue gas flows out thin-walled thermal capacitance device 7.Normal temperature air enters burner hearth 1 via thermal capacitance chamber 2 under the air inlet positive pressure of air exhaust gases passes switch valve 5.In the thermal capacitance chamber 2 li, air takes out rapidly and is stored in the heat of 3 li of thin-walled thermal capacitance devices and is warmed up to above combustion gas self-ignition point temperature levels.Along with the prolongation of heat-exchange time, thin-walled thermal capacitance device 7 is lost the ability that reclaims obvious heat of smoke gradually because of having stored increasing heat, and thin-walled thermal capacitance device 3 is lost the ability of preheated air gradually because of having emitted increasing heat.2.5 behind～the 10s, 5 actions of air exhaust gases passes switch valve, air and flue gas exchange glide path, air flows through thin-walled thermal capacitance device 3 with reflux type, and flue gas flows through thin-walled thermal capacitance device 7 with reflux type.At this moment, air enters in the stove through switch valve 5, metal hose 6 and thin-walled thermal capacitance device 7; Flue gas enters atmosphere through thin-walled thermal capacitance device 3, metal hose 4 and switch valve 5.
2.5 the action of～10s transfer valve, the ability of thin-walled thermal capacitance device 7 store heat and thin-walled thermal capacitance device 3 release heat all do not have obviously to descend, and have kept two thin-walled thermal capacitance device cooperation temperature efficiencies to be higher than 95%.In addition, a large amount of low flue gases of temperature height, oxygen concentration has been detained in the stop supplies combustion gas during transfer valve action in thermal capacitance chamber, metal hose and the burner hearth.When following one-period begins, these be detained flue gas dilutions the air oxygen concentration sent into through thin-walled thermal capacitance device honeycomb hole passage to the level that is lower than 15%.2.5～10s is whole times of discharging of high-temperature low-oxygen concentration flue gas of being detained in the stove just, the combustion gas molecule that sprays in the stove can touch the low combustion-supporting mixed airflow of temperature height and oxygen concentration all the time, therefore guaranteed to take place in the stove in whole running times the high-temperature low-oxygen air burning well, the stove internal combustion is stable, heat release is even, and flame is full of whole burner hearth.
