Embodiment 1
[0037] Please refer to figure 1 And Fig. 2, the emulsified coke slurry cyclone combustion device of the present invention includes a shell 10, an emulsified coke slurry burner 70, an oil burner and a gas burner (not shown).
[0038] The housing 10 is surrounded by a front wall 20 , a rear wall 40 , and a side wall 60 . The casing 10 is cylindrical, and a cylindrical combustion space 30 is formed inside the casing 10 . The vertical distance between the inner wall of the rear end wall 40 and the inner wall of the front end wall 20 is three times the inner diameter of the combustion space 30 .
[0039] The front end wall 20 of the housing is uniformly provided with an emulsified coke burner 70, an oil burner and a gas burner, wherein the emulsified coke burner 70 is arranged at the center of the front end wall 20, and the oil burner and the gas burner are arranged at the emulsified Below the char slurry burner 70. The emulsified coke burner 70, the oil burner and the gas burne...
Embodiment 2
[0052] Please refer to image 3 and Figure 4 , this embodiment is similar to Embodiment 1, the difference is:
[0053] The opening area of the liquid slag outlet 66 on the inner wall of the side wall 60 is approximately equal to one-twentieth of the cross-sectional area of the combustion space 30 .
[0054] The vertical distance between the inner wall of the front end wall 20 and the inner wall of the rear end wall 40 is 1.5 times the meat diameter of the combustion space 30 .
[0055] The diameter of the outlet 44 is about half of the inner diameter of the combustion space 30 , and a conical transition chamber 48 is formed between the outlet 44 and the side wall 60 of the housing 10 . That is, a flared opening is formed on the rear end wall 40 .
[0056] There are four emulsified coke slurry burners 70, and the four emulsified coke slurry burners 70 are respectively installed on the front end wall 20, and are distributed at equal intervals on the circumference with th...
Embodiment 3
[0064] This embodiment is similar to Embodiment 1, the difference is:
[0065] The emulsified coke slurry cyclone combustion device is provided with two liquid slag outlets 66 of the same size distributed at intervals, and the opening area of each liquid slag outlet 66 on the inner wall of the side wall 60 is approximately equal to one-thirtieth of the cross-sectional area of the combustion space one.
[0066] The vertical distance between the inner wall of the rear end wall 40 and the inner wall of the front end wall 20 is 4 times the inner diameter of the combustion space 30 .
[0067] The wind speed of the tangential wind delivered to the combustion space 30 by each tangential wind inlet is 28 m / s. Three groups of tangential air inlets with a total flow rate of 0.08 times the flow rate of the preheated air are arranged at intervals on the side wall of the casing 10 .
[0068] The atomization dispersion angle of the emulsified coke slurry ejected from the emulsified co...
