As seen from the above technical solution provided by the invention, single heat storage type injection boiler and the combustion method thereof that uses liquid fuel of the present invention, heating clamber is connected with first combustion chamber and second combustion chamber, the air scoop of the burner on described first combustion chamber and second combustion chamber is connected with regenerator, because such arrangement, when taking fire, in first combustion chamber and second combustion chamber, the burner on one of them combustion chamber is used for burning; And the burner on another combustion chamber is used to discharge gas fume after burning.Burning in the burner burn-out of burning, is used for smoke evacuation to the predefined time; And stop smoke evacuation at the burner of smoke evacuation, take fire.This process periodically repeats.
In the process of burner smoke evacuation, regenerator absorbs the waste heat of institute's smoke discharging; In the process of burner combustion, the heat that regenerator absorbs discharges to combustion air, and combustion air is carried out preheating, and thermal efficiency height, energy consumption are low.
Description of drawings
Fig. 1 uses the structural representation of the single heat storage type injection boiler of liquid fuel for the present invention;
Fig. 2 is that the A-A of Fig. 1 is to schematic diagram.
The specific embodiment
The single heat storage type injection boiler that uses liquid fuel of the present invention, its preferable specific embodiment as shown in Figure 1, comprise heating clamber 2, heating clamber 2 is provided with steam raising plant, heating clamber 2 is connected with first combustion chamber 11 and second combustion chamber 12, first combustion chamber 11 and second combustion chamber 12 are connected with heating clamber 2, are used for the steam raising plant heating to heating clamber 2, produce steam.
As shown in Figure 2, steam raising plant comprises coiled pipe 8, and coiled pipe 8 coils in heating clamber 2, can be surrounded on the inwall of heating clamber 2, and coiled pipe 8 can lay around the inner surface of refractory insulating layer 3, and an end of coiled pipe 8 feeds treated water; Another brings out steam.The bottom of heating clamber 2, first combustion chamber 11 and second combustion chamber 12 is provided with a plurality of cinder notch 9 that fall, and is used to clear up the lime-ash after the burning.
Be respectively equipped with at least one burner 5 on first combustion chamber 11 and second combustion chamber 12, also can establish two or more.
Referring to Fig. 1, burner 5 is connected with regenerator 6 again, and burner 5 is provided with fuel port and air scoop, and regenerator 6 is provided in a side of on the air scoop.
The combustion method of the above-mentioned single heat storage type injection boiler that uses liquid fuel of the present invention, its preferable specific embodiment is: in first combustion chamber 11 and second combustion chamber 12, burner 5 on one of them combustion chamber is used for burning, and the burner 5 on another combustion chamber is used to discharge gas fume after burning; Burning in burner 5 burn-outs of burning, was used for smoke evacuation, and stops smoke evacuation at the burner 5 of smoke evacuation to the predefined time, took fire.This process periodically repeats.Fuel used in the combustion process can be heavy oil, light oil, water-coal-slurry or water Jiao slurry etc.
In the process of above-mentioned periodic burning by turns, burner 5 is in smoke evacuation process (previous cycle), and the regenerator 6 that connects on the air scoop has absorbed the waste heat of institute's smoke discharging; And burner 5 is in the process (i.e. back one-period) of burning, and the heat of regenerator 6 absorptions discharges to combustion air, and combustion air has been carried out preheating.
In the process of burner 5 smoke evacuations, gas fume after burning enters regenerator 6 backs and discharges by regenerator 6, be provided with the low-temperature flue gas outlet after the regenerator 6, be used to discharge low-temperature flue gas, for further recovery waste heat, the outlet of low-temperature flue gas after the regenerator 6 can also be provided with waste-heat recovery device, as condenser etc., makes the thermal efficiency higher.
