Abstract
Disclosed is a Coke oven gas additional heating device of a vertical flue of a coke oven combustion chamber, which relates to a coke oven combustion chamber heating device, and comprises three systems of a blast furnace coal gas pipeline, a coke oven gas pipeline and an air pipeline, as well as a nozzle fuel positioned at the end part of a gas branch pipeline, and the heating device is characterized in that a valve is arranged on each branch pipe of coke oven gas. The utility model has the advantages that: the problem of cooling specific vertical flues can be solved by opening the coke oven gas for additional heating according to the structural scheme under the condition of severe blowby phenomena of specific combustion chambers, and the coking quality can be ensured at real time.
Description
Technical field:
The utility model relates to a kind of coke oven combustion chamber heating unit.
Background technology:
Our factory 1
#Coke oven the 66th row combustion chamber the 27th
#, 28
#Flue is owing to a variety of causes, and blowby is serious, is in low-temperature condition (temperature can only reach between 950～1000 ℃) for a long time with these two flues of blast furnace (BF) gas heating, causes 65
#The charge of coke that coking chamber coke side burner is about 1 meter is in half-cooked state for a long time, though repeatedly to 27
#, 28
#Flue air-flow approach cleans, removes coke side 66
#, 67
#The blocked state of regenerator sealing wall, inspection checker brick partly sprays the claying material to blowby simultaneously, but DeGrain.
The coke oven combustion chamber of our factory is equipped with two cover burning gas airing systems by traditional design at present, one cover is the blast furnace gas plenum system, one cover is for the coke-oven gas plenum system, and each flue of coke oven combustion chamber is all led to through each arm, a tube end static jet by main pipe line separately in two systems.As burner, two systems only are that the main pipe line initiating terminal is equipped with total valve, as long as open a total valve, supply with combustion gas just combustion gas enters each arm by main pipe line, control the total valve open degree to satisfy temperature of combustion by thermo detector.The design of two cover systems is owing to two kinds of fuel gas buring values, air pressure difference, and then its pipeline, arm, jet size difference are selected to use by producing source of the gas for the user.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of coke oven combustion chamber flue coke-oven gas supplementary heating device that utilizes the original coke-oven gas heating unit of coke oven indivedual low temperature quirks to be carried out supplementary heating is provided.
Scheme of the present utility model is: on each arm of coke-oven gas valve is installed.
Advantage of the present utility model is: under indivedual serious states of combustion chamber blowby, adopt the utility model organization plan, open coke-oven gas and carry out supplementary heating, solve indivedual flue cooling problems, guarantee the coking quality immediately.
Description of drawings:
Accompanying drawing is the utility model supplementary heating structural representation.
Embodiment:
Structure of the present utility model is: valve (4) is installed on each arm of coke-oven gas.
In the existing installation, comprise blast furnace gas pipeline (2), coke oven gas pipe (3), air line (1) system, each system all passes through main pipe line, a plurality of small transfer line feeds flue, and combustion gas small transfer line end has been equipped with nozzle.
In the coke oven combustion process, generally open the blast furnace gas total valve, give each flue air feed by total pipeline, arm, each coke-oven gas arm is in closing condition.The operator carries out thermometric with thermometric gas to each flue, find that certain flue temperature is in low-temperature condition inadequately in case patrol and examine, then open the valve (4) on this flue coke-oven gas arm, certainly the total valve on the while coke-oven gas main pipe line is in opened condition, valve on other arm (4) is in closing condition, arm valve (4) is opened and is given coke-oven gas nozzle air feed burning carrying out supplementary heating on this flue, survey temperature after the supplementary heating again with thermo detector, regulate arm valve (4) open degree according to thermometric.
This is simple for structure, has solved the coke oven blowby and has caused flue cooling problem.
Claims (1)
1, coke oven combustion chamber flue coke-oven gas supplementary heating device, comprise blast furnace gas pipeline (2), coke oven gas pipe (3), air line (1) three system, and combustion gas small transfer line end nozzle, it is characterized in that on each arm of coke-oven gas, being equipped with valve (4).
