Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, a method for building spanning holes on a 7.63m coke oven of the present invention includes a 7.63m coke oven 1 and a spanning hole on the coke oven. An interlayer 4 is arranged between the layer spanning holes, and two through holes 5 are arranged on the interlayer, and the upper and lower two layer spanning holes form interpenetrating passages 6 through the interlayer through holes. The upper spanning hole is divided into five areas, which are respectively the area 7 above the middle of the interlayer and the four areas 8 on both sides of the through hole of the interlayer. The area above the middle of the interlayer is all built with silica bricks to completely block the upper span. The holes preve...

Abstract

The invention discloses a masonry method for cross-over holes on a coke oven of 7.63m, including the coke oven of 7.63m and the cross-over holes on the oven. The holes comprise an upper layer and a lower layer, and an interlayer is arranged between the cross-over holes of the upper layer and the lower layer and provided with two through holes, the cross-over holes of the two layers form mutually communicating channels by the through holes of the interlayer, the interlayer divides the cross-over hole of the upper layer into five areas, which are respectively the area above the right middle of the interlayer and four areas at two sides of the through holes of the interlayer, the whole area above the right middle of the interlayer is the masonry with silica brick, and the upper cross-over hole is completely plugged, waste gas is prevented from flowing to adjacent flame paths; the four areas at two sides of the through holes of the interlayer adopt the refractory materials with little density and the property of heat insulation for masonry and blockage. The masonry method of the invention limits hot waste gas to flow on the upper part of a combustion chamber, takes advantage of the heat insulation property of the refractory materials to stop heat transfer, effectively prevents the temperature of the top space of the coke oven from rising and further lowers the temperature of the top of the coke oven and the consumption of gas.

Description

technical field [0001] The invention relates to a method for building a spanning hole in a 7.63m coke oven, in particular to a method for building a spanning hole in a 7.63m coke oven. Background technique [0002] The 7.63-meter coke oven is one of the world's largest coke ovens designed and developed by German Uhde company, and it is designed with adjustable spanning holes. The upper and lower design spanning the hole is mainly used to adjust the heating level and the temperature of the furnace top space to ensure the maturity of the upper coke cake. [0003] However, the system design is mainly based on coke oven gas and mixed gas with rich calorific value, while coke oven heating in my country mainly uses blast furnace gas with low calorific value as the heat source, which itself has long combustion flame, good high-direction heating, and matching points Sectional heating is sufficient to improve high-direction heating characteristics. Therefore, when blast furnace gas ...
