Abstract
Coking emissions in the regions of the roof of the coke oven and adjoining lateral wall regions are removed by removing jets of fresh air from one longitudinal side to the other longitudinal side where the air, entraining the contaminant, is collected. The collected gases are supplied to the dry and wet cleaning.
Claims19
A method of cooling a roof region of a coke oven and maintaining said roof region free from contaminants, comprising the steps of:
- (a) enclosing said roof region with a suction housing defining a space with said roof region;
- (b) continuously evacuating said space so as to maintain said space at a subatmospheric pressure;
- (c) maintaining said space in communication with at least some regions of covered filling openings and regions of coke-oven doors of said coke oven;
- and
- (d) admitting fresh air to said space in a volume substantially equal to gases evacuated from said space.
An apparatus for cooling a roof region of a coke oven and maintaining said roof region free from contaminants, comprising:
- a suction housing enclosing said roof region and defining a space with said roof region;
- means for continuously evacuating said space so as to maintain said space at a subatmospheric pressure;
- means for maintaining said space in communication with at least some regions of covered filling openings and regions of coke-oven doors of said coke oven;
- and
- means for admitting fresh air to said space in a volume substantially equal to gases evacuated from said space.
An apparatus for cooling a roof region of an elongated coke oven and maintaining said roof region free from contaminants, comprising:
- a hall-like suction housing enclosing said roof region and defining a space with said roof region;
- means for continuously evacuating said space so as to maintain said space at a subatmospheric pressure;
- means for cleaning gas evacuated from said space;
- a plurality of nozzles arrayed along one longitudinal side of said coke oven for training jets of fresh air across said roof region in a vicinity of a roof of the coke oven;
- means connected with said nozzles for feeding fresh air thereto;
- and
- means forming an exhaust chimney communicating with said space along an opposite longitudinal side of said coke oven and provided with said means for continuously evacuating said space for withdrawing some of the air blown across said roof by said nozzles.
