Embodiment Construction

[0020] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0021] Such as figure 1 , figure 2 As shown, an adjustable coke oven chute opening structure according to the present invention includes a chute 1 and a chute 2 arranged side by side corresponding to the same vertical fire passage, and a chute 1 and a chute 2 are arranged between the chute 1 and chute 2 There are nose bridge bricks 3; the nose bridge bricks 3 are movably placed on the top of the masonry in the chute area, and can be replaced; the nose bridge bricks 3 are provided with various specifications according to different heights.

[0022] The distance between the top surface of the nose bridge brick 3 and the bottom surface of the vertical fireway is -200-350mm.

[0023] The upper part of the nose bridge brick 3 is a cuboid structure, and the two sides of the lower part are arc-shaped surfaces extending outward and downward respectivel...

Abstract

The invention relates to an adjustable coke oven chute opening structure which comprises a chute I and a chute II which are arranged side by side corresponding to a same vertical flame path, wherein anose bridge brick is arranged between the chute I and the chute II; the nose bridge brick is movably arranged at the top of a chute area brickwork and can be replaced; and the nose bridge bricks of various specifications are provided for later use according to different heights. According to the invention, the nose bridge brick is improved into a movable structure from a conventional fixed structure, and the shape of a chute opening and the distance between the top surface of the nose bridge brick and the bottom surface of the vertical flame path are changed by replacing nose bridge bricks with different specifications, so that the height-direction heating uniformity of the coke oven when different types of coal gas are adopted for heating is ensured.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to an adjustable coke oven chute structure for heating coke ovens with coke oven gas or lean gas. Background technique [0002] The coke oven chute area is located between the top of the regenerator and the bottom of the combustion chamber. It is a channel connecting the regenerator and the combustion chamber. It is used to introduce air and gas and distribute them to each vertical flue, while exhausting waste gas. There are many channels in the chute area, and the gas is criss-crossed, which is the most complex structure in the coke oven. Each vertical channel of the combustion chamber is connected with the corresponding ramp: when coke oven gas is used for heating, the coke oven gas is supplied by the gas pipe brick, and the two ramps corresponding to the same vertical channel are used to supply air or Exhaust gas is exported; when lean coal gas is used for heating, among the ...
