no. 1 Embodiment approach

[0057] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0058] FIG. 1 is a diagram showing an example of the structure of a coke oven. Specifically, Figure 1A It is a longitudinal cross-sectional view showing an example of the state of the coking chamber vicinity to be measured when viewed in the depth direction of the coking chamber in the entire coke oven 100 . Figure 1B is shown in the entire coke oven 100 when viewed from the upper side of the coke oven 100 Figure 1A A cross-sectional view of the part shown in .

[0059] Such as Figure 1A As shown, in the coking oven 100 , the coking chambers 11a, 11b and the combustion chambers 16a, 16b, 16c are arranged alternately with the furnace wall 14 interposed therebetween. Coal is charged into the carbonization chamber 11a from the coal charging port 13a to manufacture coke 15 . Coke 15 is produced by dry distillation of coal using the heat from the combustion cham...

no. 2 Embodiment approach

[0173] Next, a second embodiment of the present invention will be described. In the present embodiment, as in the first embodiment, the resistance index k is obtained for the plurality of carbonization chambers 11, and the obtained resistance index k is correlated with the extrusion load generated in the plurality of carbonization chambers 11 to simulate the furnace wall. 14 patched. In this way, in this embodiment, the repair of the furnace wall 14 of the carbonization chamber 11 is assisted by using the resistance index k obtained as described in the first embodiment. Therefore, in the description of the present embodiment, detailed description of the same parts as those of the above-mentioned first embodiment will be omitted.

[0174] Figure 18 It is a figure which shows an example of the functional structure of a coke oven wall surface repair assisting device. In addition, the hardware of the coke oven wall repair assisting device 1800 is a device including a CPU, ROM,...

Abstract

An oven wall three-dimensional profile data (701) representing concave and convex amounts on all over oven walls (14R, 14L) at a right side and left side of a coking chamber (11) is generated by using image signals obtained by a wall surface observation apparatus (200). A resistance index 'k' in which a resistance received by pushed coke (15) resulting from a rising gradient existing on the oven wall (14) is indexed is asked by using the oven wall three-dimensional profile data (701). It can be verified that there is a correlation between this resistance index 'k' and a pushing load. Accordingly, it is possible to quantitatively evaluate a state of the oven wall (14) affecting on the pushing load.

Description

technical field [0001] The invention relates to a coke oven wall surface evaluation device, a coke oven wall surface repair auxiliary device, a coke oven wall surface evaluation method, a coke oven wall surface repair auxiliary method and a computer program. Give guidance on the wall. Background technique [0002] In a coke oven for carbonizing coal to produce coke, a plurality of carbonization chambers and combustion chambers are alternately arranged with furnace walls made of refractory bricks or the like interposed therebetween. When using this coke oven to generate coke, coal is first loaded from the coal charging port located on the top of the carbonization chamber. Then, a high temperature of 1000° C. or higher is applied to the coal in the carbonization chamber for about 20 hours by using the heat generated in the combustion chamber by the combustion gas. In this way, coal is dry-distilled to produce a coke cake (hereinafter simply referred to as coke). After the c...
