Embodiment
Below in conjunction with accompanying drawing this practical technique is described in detail: when work, B heat-accumulating burner 30 and 31 alternations of A heat-accumulating burner are at burning, accumulation of heat state.When A heat-accumulating burner 31 in when burning, two-position four way change valve 10 communicates A side air/flue 1 with air line 4; Simultaneously B side air/flue 28 is communicated with flue 5; A side combustion gas is meanwhile cut valve 6 soon and is opened, the combustion gas of B side is cut valve 7 soon and is closed, this moment, air was by gas blower pressurization process air flow quantity motor-driven control valve 16 dominant discharge, then through air flowmeter 11 monitorings, through two-position four way change valve 10, pass through A side air/flue 1 then, process A side regenerator 32 is air heating (heat release), warm air arrives A side premixer 33 and process gas flow motor-driven control valve 14 dominant discharge, through gas meter 13 monitorings, valve 6 is cut in combustion gas soon through the A side, supplies the combustion gas mixing and the burning that come through A side gas pipeline 3.Because air, combustion gas can both be carried out accurate flow control, have created condition for guaranteeing reducing atmosphere.Meanwhile B side secondary afterburning air is cut valve 9 unlatchings soon; A side secondary afterburning air is cut valve 8 soon and is closed; Through secondary afterburning air-breathing blower fan 25 air pressurized process secondary afterburning air flow quantity motor-driven control valve 15 dominant discharge, through 12 monitorings of secondary afterburning air flowmeter, cut valve 9 soon through B side secondary afterburning air, combustion gas superfluous in the flue gas that process B side secondary afterburning air line 34 supplies to come in next afterburning air and the stove is in this perfect combustion, the high-temperature flue gas of after-flame is lowered the temperature through B side regenerator after (accumulation of heat), through B side air/flue 28, through two-position four way change valve 10, through flue-gas temperature transmitter 29, through furnace pressure motor-driven control valve 17, discharge through smoke exhaust fan, so just realized the burning of A side, the accumulation of heat of B side.When B heat-accumulating burner 30 in when burning, two-position four way change valve 10 communicates B side air/flue 28 with air line 4; Simultaneously A side air/flue 1 is communicated with flue 5; B side combustion gas is meanwhile cut valve 7 soon and is opened, the combustion gas of A side is cut valve 6 soon and is closed, this moment, air was by gas blower pressurization process air flow quantity motor-driven control valve 16 dominant discharge, then through air flowmeter 11 monitorings, two-position four way change valve 10 then, pass through B side air/flue 28 then, pass through B side regenerator 22 then air heating (heat release), warm air arrives B side premixer 20 and process gas flow motor-driven control valve 14 dominant discharge, through gas meter 13 monitorings, valve 7 is cut in combustion gas soon through the B side, supplies the combustion gas mixing and the burning that come through B side gas pipeline 35.Because air, combustion gas can both be carried out accurate flow control, have created condition for guaranteeing reducing atmosphere.Meanwhile B side secondary afterburning air is cut valve 9 soon and is closed; A side secondary afterburning air is cut valve 8 soon and is opened; Through secondary afterburning air-breathing blower fan 25 air pressurized process secondary afterburning air flow quantity motor-driven control valve 15 dominant discharge, through 12 monitorings of secondary afterburning air flowmeter, cut valve 8 soon through A side secondary afterburning air, combustion gas superfluous in the flue gas that process A side secondary afterburning air line 2 supplies to come in next afterburning air and the stove is in this perfect combustion, the high-temperature flue gas of after-flame is lowered the temperature through A side regenerator after (accumulation of heat), through A side air/flue 1, through two-position four way change valve 10, through flue-gas temperature transmitter 29, through furnace pressure motor-driven control valve 17, discharge through smoke exhaust fan, so just realized the burning of B side, the accumulation of heat of A side.So one-period finishes, and next cycle begins; Go round and begin again, funnel temperature periodical change between 120-180 ℃ has realized the process of accumulation of heat, heat release.By the baker burner that is provided with furnace temperature is raised to 800 ℃ earlier before the work, could starts the burning of heat-accumulating burner input, control two-position four way change valve in good time by computer;
