COKE-FURNACE BLOCK

摘要

Coke-furnace block particularly with regenerators divided into two parts, for firing with strong and/or weak gas, is characterized by having lower furnaces with unequal widths in alternating sequence. Preferred embodiments include two adjacent lower furnaces together having the same width as two corresponding upper furnaces; having the center lines of the lower furnaces align plumb with the center lines of oven chambers situated above them; having the open chamber widths of two adjacent regenerators relate to each other within the limits 1:1 up to the ratio of amounts of gas to air passing therethrough during operation; having the cross-sections of gas and air channels in the furnace bottoms in the same relation to each other as the amounts of gas and air passing therethrough; and providing the regenerator checker-bricks in two adjacent regenerators with equal or unequal specific heat exchange surfaces and/or free channel cross-sections.
