The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Referring to Fig. 1 to Fig. 4, heat storage type combustion coking heater of the present utility model is mainly used in petroleum chemical industry, specifically comprises again: body of heater, bracing frame, radiation chamber, heat-storage type burner, flue gas blower unit, air air supply device and heating coil;
Wherein, body of heater is that box-structure is arranged on the bracing frame, and radiation chamber is set in the body of heater, and heating coil is set in the radiation chamber, and heating coil is made up of boiler tube and sharp turn bend pipe.In the radiation chamber one group of coil pipe can be set, many group coil pipes also can be set, each is organized, and available wall with flues separates between the coil pipe, sees and implements illustration one and two.Coil pipe can be heated by single side radiation, also can two-sided radiation be heated.On two headwalls of radiation chamber a plurality of heat-storage type burners are set, be equipped with fuel inlet and smoke evacuation/air feed mouth on each heat-storage type burner, the fuel of each heat-storage type burner is connected with pilot burner fuel gas manifold trunk with the fuel manifold trunk respectively with the pilot burner import, provide fuel by the fuel manifold trunk for each heat-storage type burner, and pilot burner fuel gas manifold trunk provides fuel for pilot burner separately, and the smoke evacuation of each heat-storage type burner/air feed mouth all is communicated with flue gas blower unit and air air supply device respectively by three-way diverter valve; An interface that is three-way diverter valve is communicated with the flue gas blower unit, and another interface is communicated with the air air supply device; The flue gas blower unit is formed by connecting by smoke evacuation manifold trunk, induced draft fan and chimney, one interface of the three-way diverter valve that each heat-storage type burner connected is connected with the smoke evacuation manifold trunk of this flue gas blower unit, thereby the smoke evacuation/air feed mouth of each heat-storage type burner is pooled on the flue gas blower unit, outwards discharges fume by smoke evacuation manifold trunk, induced draft fan and the chimney of flue gas blower unit during smoke evacuation; And the air air supply device is formed by connecting by air air feed manifold trunk and gas blower, another interface of the three-way diverter valve that is connected of each heat-storage type burner is connected with air air feed manifold trunk, thereby each heat-storage type burner is pooled on the air air supply device, gas blower is connected with outside blast main, and gas blower and air air feed manifold trunk by this air air supply device can offer the air feed of outside blast main each heat-storage type burner.
The fuel inlet of every heat-storage type burner and smoke evacuation/air feed mouth all can be provided with variable valve on each manifold trunk of access (fuel manifold trunk, smoke evacuation manifold trunk and air air feed manifold trunk) pipeline before, thereby can regulate flue-gas temperature according to being heated material temperature out control fuel flow.
Flue gas low-temperature thermal absorption device can also be set in the said system, can be material or the water pipe that absorbs flue gas low-temperature heat, and this flue gas low-temperature thermal absorption device is arranged in the smoke exhaust pipe before or after the induced draft fan of flue gas blower unit.
But the calorific value of employed heat-storage type burner based on fuel is selected single heat-accumulation combustor and two heat-accumulation combustor in the above-mentioned reforming furnace;
