Abstract

Abstract Apparatus and method for applying an adherent foamy layer of bubbles on hot coke as it is ejected from an oven of a battery of by-product coke ovens, wherein a box-like housing extends outwardly from a coke oven guide carriage and over a coke transfer car which car is on a level below the coke oven guide carriage; the housing having an open end facing and alignable with the coke oven and having an open bottom side; and means associated with the housing for generating and applying a foamy coating onto the mass of coke as it passes through the housing; and the foam generating means being mounted on the housing, whereby the foamy coating excludes air from the coke and encompasses any fumes and dust generated by the coke during its ejection and fall into the transfer car.
