Description
Technical field
The present invention relates to a kind of new gooseneck metallurgy coking gas controller.
Background technology
Various technologies have been developed to reduce the loss of coke-stove gas.From the coke-oven coal of fire door, charging hole lid etc. loss
Gas has been reduced to the limit that can not technically subtract again.Wherein essence limiting factor is collecting main pressure and the charing being connected
Substantial connection between chamber pressure be present：Caused raw coke oven gas amount change very greatly, starts caused raw coke oven gas amount phase among coking
When big and caused raw coke oven gas amount very little at the end of coking.Refractory material is damaged to avoid surrounding air from penetrating into coke oven, it is necessary to
During whole coking or even at the end of coking, the pressure stability in coke furnace carbonization chamber will be made to be maintained at certain scope
It is interior.And the method for pressure stability is kept the negative pressure of discharge is also stably held in certain scope.But coking is opened
The gas occurred during the beginning diffuses to form higher pressure strongly may cause raw coke oven gas from the outside loss of fire door.
