Embodiment Construction

[0015] A method for improving the total coke rate of a heat recovery coke oven in this embodiment comprises the following steps:

[0016] 1) Set 4 primary air inlets on the roof of the heat recovery coke oven, respectively marked as 1#, 2#, 3# and 4#, and set the air inlet opening dials next to the 4 primary air inlets for passing through The air inlet cover quantitatively controls the air intake. The dial is evenly divided into 6 equal parts and marked with 6 / 6, 5 / 6, 4 / 6, 3 / 6, 2 / 6, 1 / 6 and 0 scales, of which 6 / 6 means the primary air inlet is fully open, 0 means the primary air inlet is fully closed;

[0017] 2) After loading the briquettes into the carbonization chamber of the heat recovery coke oven, set the openings of the four primary air inlets on the top of the heat recovery coke oven to full open state, and adjust the opening of the primary air inlets according to the coking time, Simultaneously adjust the temperature of the carbonization chamber of the heat recovery...

Abstract

The invention belongs to the technical field of the coking method and specifically relates to a method of improving a total coke rate of a heat recovery coke oven. The method mainly solves technical problems that the coking of coke cake surfaces easily gets out of control, the coking temperature is difficult to control, the coking of the coke cakes is easily increased and the over-coking of the coke occurs easily in the present heat recovery coke oven. The technical scheme is as follows: five primary air inlets are arranged at the top of the heat recovery coke oven; after coal cakes are placed in a coking chamber of the heat recovery coke oven, the openness of the four primary air inlets at the top of the heat recovery coke oven are set as an full-open state; the openness of the primary air inlets is adjusted according to the coking time, and meanwhile, the temperature of the coking chamber of the heat recovery coke oven and the temperature of a four-joint arched fire channel are adjusted; after the coking of 72 hours, the burning in the coking chamber of the heat recovery coke oven is observed; once the flame in the coking chamber disappears, the coked cakes are discharged out of the oven immediately. The method of improving the total coke rate of the heat recovery coke oven has the advantages of easy control of the coking temperature, high quality of the coked cakes and high yield of single oven of the coked cakes.

Description

technical field [0001] The invention belongs to the technical field of coking methods, and in particular relates to a method for improving the total coke rate of a heat recovery coke oven. Background technique [0002] Heat recovery coke oven is a coke production device. The existing heat recovery coke oven is always in a negative pressure state during the entire coking process. After the tamped briquettes are loaded into the furnace, the 5 primary air inlets on the top of the furnace are equipped with air to heat the briquettes in the form of thermal radiation. The unburned gas passes through the descending channel on the furnace wall and enters the quadruple arches for secondary air distribution to heat the briquettes by means of heat conduction. However, due to the entry of air from the primary air inlet on the furnace top, the coke on the surface of the coke cake will be out of control. On the other hand, due to the entry of air, it is difficult to control the coking te...
