Abstract

The utility model relates to a thermal recovery steam injection boiler matching device in an oil field, in particular to a water coke slurry combustion device which comprises a steam injection boiler, wherein a stable combustion chamber is additionally arranged on one side of the steam injection boiler, a water coke slurry combustor, a crude oil combustor, a natural gas combustor and an ignition electrode are arranged on the steam injection boiler, the upside and the downside of the stable combustion chamber are respectively provided with a tangential air hole, and the lower end of the stable combustion chamber is provided with an ash remover. The water coke slurry combustion device realizes easy ignition of water coke slurry in the steam injection boiler, has the advantages of stable combustion, easy ash removal and high heat efficiency, and overcomes the defects of difficulty in ignition, instable combustion, difficulty in ash removal, and low heat efficiency of the traditional water coke slurry in the steam injection boiler.

Description

Water coke slurry combustion apparatus

Technical field:

The utility model relates to a kind of oil thermal recovery injection boiler corollary apparatus, particularly a kind of water coke slurry combustion apparatus.

Background technology:

The steam injection heating exploitation is the major way of viscous crude field exploitation, the heat-collecting steam boiler of on-the-spot operation adopts crude oil to act as a fuel usually, the oil burner that crude oil is delivered in the boiler furnace by petroleum pipeline burns, send heat to boiler tube and heat the water that comes in it, produce the steam that meets the steam injection standard.Yet existing petroleum resources are valuable, adopt the oil production cost height that acts as a fuel, and when adopting the burnt slurry of water to act as a fuel, the burnt slurry of water difficult point fire in injection boiler, combustion instability, the ash disposal difficulty, the thermal efficiency is low.

The utility model content:

The technical problems to be solved in the utility model provides a kind of water coke slurry combustion apparatus, and this device has been realized the easily igniting in injection boiler of the burnt slurry of water, flameholding, and easily ash disposal, the thermal efficiency is high.Overcome the burnt slurry of existing water difficult point fire in injection boiler, combustion instability, ash disposal difficulty, the deficiency that the thermal efficiency is low.

Technical solution adopted in the utility model is: a kind of water coke slurry combustion apparatus comprises injection boiler; Set up stable burning room in injection boiler one side, the burnt slurry of water burner, crude oil burner, neat gas burner and ignitor are installed in the stable burning room, stable burning room all has up and down tangential air port, and the stable burning room lower end is provided with soot blower.

The number of the burnt slurry of water burner is 6.

The beneficial effects of the utility model are: the utility model is set up stable burning room owing to having adopted, and in stable burning room the mode of the burnt slurry of water burner, crude oil burner, neat gas burner and ignitor is installed, thereby have the burnt slurry of water easily igniting, combustion stablized effect in injection boiler; Owing to adopted the mode that is provided with soot blower in the stable burning room lower end, thereby had the advantage of easy ash disposal; The utility model thermal efficiency is high, greatly saves crude oil, reduces production costs.

Description of drawings:

The utility model is described in more detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the left view of Fig. 1.

The specific embodiment:

As shown in Figure 1 and Figure 2, a kind of water coke slurry combustion apparatus comprises injection boiler 2; Set up stable burning room 1 in injection boiler 2 one sides, the burnt slurry of 6

water burner

3,2 crude oil burners 6,2 neat gas burners 7 and 1 ignitor 8 are installed in the stable burning room 1, stable burning room 1 all has up and down tangential air port 5, and stable burning room 1 lower end is provided with soot blower 4.

When the utility model uses, light a neat gas burner 7 by ignitor 8, refire another neat gas burner 7, light subsequently two crude oil burners 6, after stable burning room's 1 temperature reaches about 750 ℃, light the burnt slurry of water burner 3, at this moment the burnt slurry of water burns be atomized into the mist torch under the high-pressure blast effect after.This moment accompanied combustion by former oil gun always, until determine the 3 normal smooth combustions of the burnt slurry of water burner.A large amount of thicker dust deposits that combustion process produces are got rid of through soot blower 4 in the bottom of stable burning room 1, and remaining fine dust discharges out of the furnace with flue gas.

Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
