CONTINUOUS VERTICAL-FLUE MULTICHAMBER COKE OVEN Russian patent published in 1995 - IPC

FIELD: coke production. SUBSTANCE: heating walls are located in floor: metal pipes are arranged in separating walls between chambers, under and above channels for withdrawal of gases after coke cooling, in channels themselves for withdrawal of said gases. Metal pipes are communicated to one another through headers. Built in oven end wall against heating flues are air supply ducts communicating with metal pipes. External and adjacent to brickwork flanges of girders of anchor columns and their end faces are interconnected to form communicating spaces. Built in side front walls of regenerators are bypass flues communicating with spaces and vertical receiving-distributing flue of regenerator. EFFECT: higher degree of heat utilization due to reduced external heat losses of heated oven surfaces with combustion products from heating system and gases after coke cooling. 5 dwg
