Problems solved by technology

[0002] The existing four 6m coke ovens of Linhuan Coking Company were put into operation in succession from 2006 to 2007, but they have been subject to high furnace temperature and uneven temperature, inadequate equipment management and maintenance, and unskilled workers in operation. Furnace production has been in the stage of barely maintaining production for a long time
With the implementation of the company's various strengthening management measures, the coke oven production can complete the production tasks under various load conditions, and the coke oven production management and staff operation level have also been improved accordingly, but the K3 coefficient reflecting the coke oven production stability and overall management level is still relatively low. Low

Embodiment

[0028] (1) The specific method of operation of the coal loading car is as follows:

[0029] A. To optimize the coaling operation of the coaling vehicle, that is to adopt the new coaling method of "first 1# coke oven, 4# coke oven, then 2# coke oven, 3# coke oven". # coke oven, 4 # coke oven coal filling holes to add coal for 12 turns, then start to add 2 # coke ovens, 3 # coke ovens, and then add coal to the coal filling holes of 4 coke ovens at the same time; this operation method effectively improves Coal addition and reduced coal addition time; (The K3 coefficients of 1# coke oven, 4# coke oven, 2# coke oven and 3# coke oven are as follows figure 1 shown)

[0030] B. Stop the spiral when the coaling truck adds coal to 50 revolutions, and use low-speed coaling when the coal leveling starts; this operation method prevents smoke from the small furnace door and reduces the probability of coal extrusion;

[0031] C. Reset the running frequency conversion and spiral frequency ...

Abstract

The invention discloses a coking operation method for effectively improving the production operation coefficient of a coke oven. The method comprises concretely comprises the following steps: 1, carrying out a coal feeding vehicle operation: optimizing the coal feeding operation of a coal feeding vehicle: adopting the following "1# coke oven, 4# coke oven, 2# coke oven and 3#coke oven" new coal feeding mode: adding coal to the coal adding holes of the 1# coke oven and the 4# coke oven 12 revolutions in the coke feeding process of the coal feeding vehicle, adding the coal to the 2# coke oven and the 3#coke oven, and simultaneously adding coal to the coal adding holes of four coal ovens; 2, carrying out a coke barrier vehicle operation: changing the power of the oil air cooler of the coke barrier vehicle to 16000 BTU / H from 8000 BTU / H; and 3, carrying out a coke pushing vehicle operation: changing the coal leveling mode to "two long and three short" mode from "three long and two short". Operation mode optimization and device reconstruction reduce the average coal leveling time by 56s, and provides time guarantee for improving the K2 coefficient.
