Transverse continuous heating system of coke oven

Abstract

The invention relates to a transverse continuous heating system of a coke oven. The transverse continuous heating system comprises a cuboidal combustion chamber which is arranged at an interval with a carbonization chamber and built by silicon bricks, wherein the combustion chamber is divided into a left cavity and a right cavity by an internal partition wall; the cavity on each side is longitudinally divided into an even number of horizontal flame paths; the flame paths in the highest layers are provided with flue gas outlets, and the flame paths in the odd number-layers are equipped with combustors; heat exchange chambers are respectively arranged on the two sides of the combustion chamber, and the heat exchange chambers comprise a lean coal gas heat exchange chamber and an air heat exchange chamber which are horizontally arranged and have the same structure; each combustor and each flue gas outlet are communicated with the heat exchange chamber, and flue gas and heated gas perform continuous countercurrent recuperative heat exchange in the heat exchange chambers. The transverse continuous heating system provided by the invention changes a complex vertical intermittent alternate heating and heat accumulation system of the existing coke oven, changes the longitudinal complex connection relation and the operation method of a heat accumulation chamber of the coke oven, cancels a complex vertical flame path, a long coke oven, a short chute, checker bricks, a small flue and grate bricks, reduces the number of special-shaped bricks, and cancels a heat exchanger and other equipment; the transverse continuous heating system has the advantages of simple structure of an oven body, convenience in operation and low investment.

Description

Technical field [0001] The invention relates to a transverse alternating heating system for a coking oven, belonging to the technical field of conventional coking in 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 body of the coke oven can be divided into the upper heating dry distillation zone, the middle heat storage zone, and the lower part is the heating gas and flue gas in and out zone. In the upper part of the furnace body, there are dozens of carbonization chambers and dozens of combustion chambers. The heating gas is burned in the combustion chamber to provide heat to the carbonization chamber through the furnace wall. The coal is heated and dry distilled in the carbonization chamber to generate coke. The combustion chamber is composed of 20-30 vertical fire channels, and each two vertica...

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
