COKE FURNACE CROSSOVER REPAIR Russian patent published in 2015 - IPC C10B29/00 F27D1/04 

FIELD: oil and gas industry.

SUBSTANCE: inventions may be used in coke industry. The coke furnace crossover includes the first row (4-5) having the first blocks (48) and the second row (6-7) having the first blocks (50i). Each of the first blocks (48) has the first horizontal aperture (72) continuing through the first block from the front surface up to the rear surface and the second vertical aperture (74) formed through the upper surface of the block continuing into the first horizontal aperture (72). The first blocks (48) are placed at flat surface combining the corresponding first horizontal apertures (72) so that the first horizontal channel (32) is formed. Each of the second blocks (50i) includes the third vertical aperture (80) continuing through the second block (50i) from the upper surface up to the lower surface. The second blocks (50i) are placed over the first row (4-5) of the first blocks (48) to match the third vertical aperture (80) of each of the second blocks (50i) with the second vertical aperture (74) of the first block so that the second vertical channel (30) is formed.

EFFECT: inventions allow decreased destruction and increased service life for coke furnace crossovers as well as reduced or excluded gas loss in the coke furnace thus improving its efficiency.
