Heating level-regulable coke oven structure and heating level regulation method

Abstract

The invention relates to a heating level-regulable coke oven structure and a heating level regulation method. The top of each vertical flue of a coke oven is provided with a spanning hole which is communicated with a duplex flue, the spanning holes are an upper layer of spanning holes and a lower layer of spanning holes, and isolating layers are arranged between the upper layer of spanning holes and the lower layer of spanning holes; a lug boss is arranged on one or two sides of each isolating layer, lug bosses are also arranged at corresponding positions on vertical flue partitions of the corresponding sides, and each two corresponding lug bosses cooperate to form a bearing platform; and a plurality of spanning hole-adjusting bricks are movably arranged on each bearing platform, and can partially or completely close an air flow passage at a corresponding position. According to the invention, air flow which passes through the upper layer of spanning holes and the lower layer of spanning holes can be accurately regulated to change the heating level of the coke oven, and thereby the temperature of the top space of a coking chamber is regulated; the regulation process is simple and convenient, and moreover, the measurement of vertical flue temperature cannot be affected.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a coke oven structure with adjustable heating level and a heating level adjustment method. Background technique [0002] The distance difference between the top of the coke oven carbonization chamber and the top of the coke oven vertical flue is called the heating level of the coke oven, and the heating level is an important dimension in the structure of the coke oven body. If the heating level is too small, the temperature of the top space of the carbonization chamber will be too high, which is not conducive to improving the quality and yield of the chemical products, and will also increase the formation of graphite on the top of the furnace; if the heating level is too high, it will reduce the temperature of the upper coke cake and affect the uniform maturation of the coke cake. . [0003] At present, the heating level of most coke ovens is a fixed parameter. In the actual ...

Problems solved by technology

However, because the mopan bricks are too large, it is difficult to adjust, and there is no way to make precise adjustments; therefore, the mopan bricks are basically not adjusted during the actual production of coke ovens, thus losing the role of the upper and lower layers across the holes

In addition, when the vertical fire path is completely blocked by grinding bricks, the fire viewing hole is actually covered, making it impossible to manually measure the temperature of the vertical fire path
