Transverse reciprocating heating system of coke oven

Abstract

The invention provides a transverse reciprocating heating system of a coke oven. The transverse reciprocating heating system comprises a cuboid combustion chamber which is constructed by silica bricks and is separated from a charring chamber, the inner part of the combustion chamber is divided vertically into a plurality of horizontal flame path, two sides of the combustion chamber are provided with ports; regenerative chambers are arranged on two sides of the combustion chamber; the inner part of each regenerative chamber is divided vertically into a plurality of heat exchanging channels; each heat exchanging channel comprises two sub channels arranged horizontally; the inner port of each heat exchanging sub channel of the regenerative chambers on two sides is connected with ports of two sides of the horizontal flame paths of the combustion chamber; the outer ports of the heat exchanging channels of the regenerative chamber are connected with a lean gas vertical pipe, an air vertical pipe and a smoke vertical pipe respectively. Two ends of each horizontal flame path are also provided with coke oven gas ports respectively. The vertical heating system is changed to be the transverse heating system, the quantitative supply of heating gas is realized, the problems of high resistance, uneven heating, difficult adjustment and the like of the existing coke oven heating system are solved, the long and short chutes of a chute area, a horizontal small flue and grate bricks are eliminated, the amount of irregular bricks is reduced, and therefore the transverse reciprocating heating system has the advantages of simple structure, convenience in operation, saving of investment and the like.

Description

technical field [0001] The invention relates to a transverse reciprocating heating system of a coke oven, which belongs to the conventional coking technical field of the coking industry of the metallurgical industry. Background technique [0002] The existing large-scale conventional mechanical coke oven can be divided into heating system and carbonization system according to the process flow. The main body of the coke oven can be divided into the upper heating and carbonization area, the middle heat storage area, and the lower part as the heating gas and flue gas entry and exit area according to the functional area. On the upper part of the furnace body, dozens of carbonization chambers and dozens of combustion chambers are distributed alternately. The heating gas is burned in the combustion chamber to provide heat to the carbonization chamber through the furnace wall, and the coal material is heated and carbonized in the carbonization chamber to form coke. The combustion c...

AI Technical Summary

Problems solved by technology

It can be seen that the existing coke oven heating gas and flue gas flow up and down, multiple vertical to horizontal or horizontal to vertical transformations, multiple vertical splits or confluences, the air flow is difficult to balance, the heating temperature is uneven, and the flow The way is unreasonable, the system resistance is large, the structure is complicated, and the temperature control is difficult to adjust
