Regulating the heating of blast furnace red- - ucing gasses

摘要

A heat exchanger works on an inversion cycle i.e. while one component is accumulating heat, the equal and opposite component is heating gas. In addition to entry and exit valves for reducing gas, air and combustibles, four regulating valves are provided (1) on the main combustion air channel, (2) on the main combustible channel (3) on the feed pipe for cold reducing gas to the heating cells, and (4) on the pipe connecting the fume outlets from the heating cells to the chimney.
