Abstract
An apparatus for equalizing the pressure in shaft furnaces which are operated at a pressure in excess of atmospheric pressure. At least one storage bin is connected to the furnace chamber, although isolated from the atmosphere and the furnace chamber by sealing valves. A gas pipeline serves to selectively supply or exhaust gas to the storage bin to equalize pressure. In one embodiment of the invention, two storage bins are interconnected by a gas pipeline and appropriate valves for equalizing pressure between the storage bins.
