Problems solved by technology

It can be seen from the above analysis that, firstly, the backfired coal-water slurry liquid slagging combustion furnace is not suitable for the combustion of emulsified coke slurry; secondly, the combustion chamber temperature of the backfired coal water slurry liquid slagging combustion furnace is still low The ash melting point of the emulsified coke slurry ash cannot be reached, and the emulsified coke slurry ash cannot be liquefied; finally, the combustion chamber structure of the reverse combustion type coal-water slurry liquid slagging combustion furnace is complicated, and the manufacturing

Embodiment 1

[0055] Please refer to Fig. 1, Fig. 2 and Fig. 3, the glass kiln of the present invention includes a kiln body and an emulsified coke slurry burning device. Among them, the kiln body includes a furnace 402 filled with glass 4022, a flame inlet 405 opened at the front end of the furnace 402, a flue gas outlet 406 opened at the rear end of the furnace 402, and a first pipe connected to the flue gas outlet 406 of the furnace body through pipes. A regenerator 408 and a second regenerator 409 . The emulsified coke slurry combustion device includes a shell 10 , an emulsified coke slurry burner 70 , an oil burner (not shown in the figure), a gas burner (not shown in the figure) and a slagging device 500 . The emulsified char slurry combustion device communicates with the flame inlet 405 of the furnace 402 through the hot air pipe 104 .

[0056] Specifically, the first heat storage chamber 408 and the second heat storage chamber 409 communicate with a main pipe 407 through the first ...

Embodiment 2

[0081] Please refer to Figure 6 and Figure 7, this embodiment is similar to Embodiment 1, the difference is:

[0082] Four regenerators that work alternately are used, and four reversing valves are used to adjust the working state of each regenerator. Two of them release heat at the same time, and the other two store heat at the same time.

[0083] 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 .

[0084] 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 inner diameter of the combustion space 30 .

[0085] 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 ...

Embodiment 3

[0094] This embodiment is similar to Embodiment 1, the difference is:

[0095] Each heat storage chamber includes three heat storage modules arranged at intervals, which are checker bricks, ceramic balls and checker bricks.

[0096] The glass kiln using the emulsified coke slurry 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 three times the cross-sectional area of ​​the combustion space. one tenth.

[0097] The two liquid slag outlets 66 are surrounded by the same transition cavity 666 and are connected to the slag holding space 505 of the same slag discharge vehicle 500 .

[0098] 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 .

[0099] The wind speed of the tangential wind deliv...

Abstract

The glass kiln with emulsified coke slurry burner includes one kiln body and one emulsified coke slurry burner. The kiln body includes one hearth, one flame inlet and one fume outlet. The emulsified coke slurry burner includes one casing forming one inside cylindrical burning space, at least one emulsified coke slurry burning unit, at least one oil/gas burner, one outlet communicated via hot blast pipe to the flame inlet of the hearth. The glass kiln includes also two or more switchable heat accumulating chambers connected via pipeline with the fume outlet of the kiln body. The present invention has double heat accumulation with lattice brick and ceramic ball reaching a heat accumulating temperature as high as 1200 deg.c to make up the low heat value emulsified coke slurry.

Description

technical field [0001] The invention relates to a glass kiln, in particular to a glass kiln using an emulsified coke slurry burning device. Background technique [0002] Generally speaking, the relatively clean energy currently used by glass kilns is mainly oil, natural gas or coal gas, etc. However, this has greatly increased the fuel cost of glass kilns, seriously affecting the survival of enterprises that use and manufacture glass kilns. [0003] For this reason, those skilled in the art are working hard to develop new available energy sources. Inexpensive, efficient and clean emulsified coke slurry fuel has gradually become a new favorite in this field. The use of emulsified coke slurry fuel in the glass kiln can not only make reasonable use of natural resources, but also reduce the fuel cost of the glass kiln. Therefore, countries all over the world are vigorously promoting the emulsified coke slurry combustion technology. [0004] However, when emulsified coke slurry...
