In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and for example, can be to be fixedly connected with, connect integratedly, can be also to removably connect; It can be the connection of two element internals; Can be to be directly connected, also can indirectly be connected by intermediary, for the ordinary skill in the art, can concrete condition understand the concrete meaning of above-mentioned term in the utility model.
Please refer to shown in Fig. 1, the utility model heat storage burner includes burner hearth 1, by first, connect air port 2, the second respectively connects the first regenerator 3 that air ports 14 connect burner hearths 1 and the second regenerator 12, is connected in four-way change-over valve 8, the air blast 11 being connected with four-way change-over valve 8 and air-introduced machine 6 between the first regenerator 3 and the second regenerator 12.Wherein, also comprise that one extends into the burner 13 of burner hearth, burner is connected with fuel supply pipe road 4, and fuel supply pipe road end is connected with fuel duty control device 16.
Between the first regenerator 3 and four-way change-over valve 8, by the first connecting pipe 5, be connected; And by the second connecting pipe 9, be connected between the second regenerator 12 and four-way change-over valve 8.Four-way change-over valve 8 connects air blast 11 by intake stack 10, by exhaust duct 7, connects air-introduced machine 6.
As shown in Figure 2, fuel duty control device 16 includes the automatically controlled block valve 162 of a bypass duct 161, one and a safety valve 163.Wherein, the computer of automatically controlled block valve 162 in electrical control cubicles controlled automatically.Computer program is set reversal valve 8 certain hour before commutation and is closed 16-2 and block main fuel pipe, and the fuel flow rate that at this moment flows into burner hearth is supplied with through bypass duct 161, and its flow is about 20% when normal.Like this in regular hour internal furnace fuel minimizing, amount of oxygen accumulation.Reversal valve completes commutation, because commutation flue gas melts down the oxygen deficiency that causes by the oxygen replenishment accumulating in burner hearth.After smoke backflow completes, 0.1-0.5 computer second automatic command control block valve 16-2 opens, and recovers normal fuel supply.By debugging, close and open the time of main fuel pipe, in commutation process, can reach rational air-fuel ratio completely, eliminate the generation of black smoke completely.
During work, normal temperature air is by air blast 11 air blast, through intake stack 10, four-way change-over valve 8, while entering the first regenerator 3 through the first connecting pipe 5 again, the heat of the fire-resistant heat-storing sphere in the first regenerator 3 has been passed to air, make atmosphere temperature rising reach 1100 ℃ of above high temperature, through the first connection air port 2, enter burner hearth, the fuel combustion that this high temperature air is supplied with burner 13 in burner hearth; Combustion product (flue gas) enters the second regenerator 12 through the second connection air port 14, and heat is passed to the fire-resistant heat-storing sphere in the second regenerator 12.Flue-gas temperature is reduced to below 150 degree from 1200 degree, from the second connecting pipe 9, four-way change-over valve 8, exhaust duct 7 and air-introduced machine 6, is discharged into environmental protection flue.
After reversal valve 8 commutations, normal temperature air is by air blast 11 air blast, through intake stack 10, four-way change-over valve 8, while entering the second regenerator 12 through the second connecting pipe 9 again, fire-resistant heat-storing sphere in the second regenerator 12 from heat absorption, become heat release, heat has been passed to air, make atmosphere temperature rising reach 1100 ℃ of above high temperature, through the second connection air port 14, enter burner hearth 1, the fuel combustion that this high temperature air is supplied with burner 13 in burner hearth; Combustion product (flue gas) enters the first regenerator 3 through the first connection air port 2, at this moment the fire-resistant heat-storing sphere in the first regenerator 3 is no longer heat release but absorbs the heat in flue gas, the temperature of flue gas is dropped to below 150 degree, from the first connecting pipe 5, four-way change-over valve 8, exhaust duct 7 and air-introduced machine 6, be discharged into environmental protection flue.
As can be seen here, along with the commutation of reversal valve, from the gas the first connecting pipe 5 to second connecting pipes 9 and heat flow direction switching direction all.Air inlet, fume emission are changed repeatedly, and variation is also followed in flame-proof sphere heat release, accumulation of heat, and combustion air temperature remains at 1000-1100 ℃, and (, exhaust gas temperature lower 80 ~ 150 ℃ than furnace temperature also remains at below 150 degree.So just a large amount of fume afterheats has been transmitted back to burner hearth inside and has reused, reached energy-conservation object.
In the utility model embodiment, described four-way change-over valve 8 and automatically controlled block valve 162 are all placed under the control of computer, will be set as 60 seconds commutating period.When system igniting runs to 58 seconds, automatically controlled block valve 162 cuts off main fuel pipeline, instruction reversal valve 8 commutations in the time of 60 seconds.Reclocking after commutation, after 1 second, automatically controlled block valve 162 is opened main fuel pipeline, with this, circulates.Result of the test authentication system has been eliminated the black smoke phenomenon producing while switching completely.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
