D. according to process 1) in step a~step e, realize focusing furnace superintendent to distribution of air flow by bottom adjustable plate structure
Carry out accurate adjustment.
Coke oven is made up of carbonization chamber 3, combustion chamber 2, regenerator 5, chute 4, furnace roof, flue etc., in carbonization chamber 3 coal charge every
Be heated change coke under exhausted air conditionses.One coke oven has tens carbonization chambers 3 and the alternate configuration in combustion chamber 2, uses refractory material
Separate.There is 20-30 flue each combustion chamber 2.Coal gas and air by preheating from regenerator 5 are in flue bottom
Meet burning, heat is provided from side to carbonization chamber 3.Regenerator 5 is located at the bottom of coke oven, is separated by regenerator partition wall 8, profit
The coal gas and air of heating are preheated with high-temp waste gas, the bottom of each regenerator 5 is designed with bottom flue 1.Chute 4 is connection
Regenerator 5 and the slanted channel of combustion chamber 2.Furnace roof is coaling and hole and rises pore and lead to carbonization chamber 3, is used to load coal charge and is led
Go out the raw coke oven gas produced during coal charge destructive distillation.Furnace roof is additionally provided with peephole and leads to each flue, is used for thermometric and inspection flame,
According to detection structure, temperature and pressure is adjusted.Each regenerator 5 is connected by exhaust gas disc with flue, one end connection cigarette of flue
Chimney.
In order to play the production capacity and best hot working efficiency of coke oven to greatest extent, needed in coke oven production process
Temperature adjustment is carried out to coke oven at any time., it is necessary to change according to situations such as coal charge, heating gas and atmospheric conditions when coke oven is normally produced
Change, heat supply adjusted in time, make the charge of coke of each carbonization chamber 3 in the coking time of regulation along it is long to height to being uniformly smelt coke.
Though therefore coke oven there are various type of furnaces, there is common basic demand：Seek to ensure that coke oven is long to equal to heating with height first
Even, heat levels are appropriate, lost with the cracking for mitigating chemical products.
The utility model sets bottom adjustable plate structure by the top of bottom flue 1, the bottom of regenerator 5, while in chute 4
