Problems solved by technology

In traditional ovens, in order to accurately control the gas flow required by the oven, in addition to adjusting through the cock, independent orifice plates of various diameters are also set separately for adjustment, but it takes a long time to replace the orifice plate, and it is easy to check the replaced orifice plate Therefore, it is very important to develop a regulating device that can quickly control the gas flow.

Embodiment 1

[0037] see now figure 1 and figure 2 , figure 1 It is a structural schematic diagram of a gas regulating device for a coke oven oven burner according to an embodiment of the present invention, figure 2 It is a structural schematic diagram of the regulating plate of the embodiment of the present invention. As shown in the figure, the gas main pipe 3 is arranged on the temporary support 3 of the platform 1 on the coke side, and the main gas pipe is 250 mm away from the platform on the coke side;

[0038] The cock 9 communicates with the gas main pipe 3 through a branch pipe, and is respectively connected with the lower flange 5 welded on the lower branch pipe 4 and the upper flange 6 on the upper branch pipe 7 through the upper flange bolts 11; The tube is connected to the burner of the coke oven;

[0039] The adjusting plate 8 is rectangular, 800mm long and 60mm wide, made of 304 stainless steel plate with a thickness of 1.5mm, and 6 small holes 81-86 with different apert...

Embodiment 2

[0041] The using method of the gas regulating device for the coke oven oven burner of the present invention is characterized in that comprising the following steps:

[0042] a. Gas selection for different coke oven ovens;

[0043] The coke oven oven adopts coke oven gas, and its calorific value is 4100Kcal / Nm 3 , CH 4 Volume content 26%, H 2 Volume content 60%, N 2 Volume content 4%, other 10%. When the excess air coefficient is 1.25, the smoke generated, H 2 O volume content 20%, N 2 Volume content 70%, C 2 O volume content 6.5%, O 2 The volume content is 3.5%.

[0044] b. Determine the diameter of the oven main pipe, lower branch pipe and upper branch pipe on both sides of the coke oven machine coke

[0045] Coke oven gas is selected, and the external pipe network pressure is 3000Pa. The diameter of the gas main pipe on the coke side is φ356×6, and the material is Q235A. The upper and lower branch pipes connected to the main pipe are usually φ48×3.5 steel pipes, an...

Abstract

A fuel gas adjusting device for a coke oven roasting burner comprises a main fuel gas pipe, a rotary plug and an adjusting plate, and is characterized in that the main fuel gas pipe (3) is arranged on a temperature support (3) of a machine coke side platform (1), the rotary plug (9) is communicated with the main fuel gas pipe (3) through a branch pipe, and is connected with a lower flange (5) welded to a lower branch pipe (4) and an upper flange (6) welded to an upper branch pipe (7) through upper flange bolts (11), and the adjusting plate (8) is rectangular and is provided with six small holes (81-86) with different hole diameters at the equal space of 130 mm in the longitudinal direction. When the adjusting plate is used, the upper flange bolts (11) are loosened, the adjusting plate is moved, the corresponding hole of the adjusting plate is aligned with the center of the rotary plug, and the corresponding positioning gear is matched with the bolt of the upper flange. The fuel gas adjusting device has the advantages that the adjusting plate with the holes is arranged, fuel gas is adjusted and accurate positioning is achieved through the hole diameter of the same specification, and use is convenient, safe and efficient.

Description

technical field [0001] The invention relates to a gas regulating device, in particular to a gas regulating device for a burner of a coke oven. Background technique [0002] After the coke oven masonry and equipment installation, the coke oven needs to be baked. On the one hand, the free moisture in the furnace body and the crystallization water at a certain temperature stage must be removed. In addition, the high temperature performance of the refractory material needs to be realized, so as to meet the normal production requirements of the coke oven. . The quality of the oven directly affects the service life of the coke oven, but how to control the temperature curve of the oven is an important link in the operation of the oven. In traditional ovens, in order to accurately control the gas flow required by the oven, in addition to adjusting through the cock, independent orifice plates of various diameters are also set separately for adjustment, but it takes a long time to re...
