HORIZONTAL-FLUE OVEN Russian patent published in 1995 - IPC

FIELD: horizontal-flue ovens. SUBSTANCE: horizontal- flue oven cocking chamber, heating walls which consist of vertical heating flues connected in pairs by means of cross-over and recirculation ports inside each pair. Each extreme pair of heating flues of heating wall has end additional heating flue which is connected with them in upper part of their separating wall by means of crossover port. Coke oven also has flues for supply of heating gas from distributing headers and communicating ducts for air supply from regenerators to heating flues. Vertical heating flues of extreme pair have individual communicating ducts running to adjacent regenerators. Communicating duct of end additional heating flue is made in brickwork for communication with atmosphere. End additional heating channel is connected with two adjacent distributing headers by means of one or two flues for supply of heating gas. Base of end additional heating flue is somewhat raised under the base of adjacent heating flue through 0.05-0.15 of height of the latter. Separating wall between additional and adjacent heating flues in its lower part is made solid. EFFECT: higher efficiency. 3 dwg, 2 tbl
