Abstract
PURPOSE: To recover heat easily without installing any heat exchanger on the outside part of an evaporating vessel by flowing and supplying an aqueous inorg. chemical soln. down into the vapor phase part of the evaporating vessel and allowing the same to contact the superheated steam existing in the vapor phase part.
CONSTITUTION: An aqueous inorg. chemical soln. is dropped from a liquid supply pipe 3 into the vapor phase part 2 of an evaporating vessel 1. Otherwise, a packed bed 6 is provided in the part 2 of the vessel 1, and said soln. is supplied and irrigated from the port 3 into this bed 6. There are no limits for the amount of the aqueous inorg. chemical soln. to be flowed down into the vapor phase part of the evaporating vessel; the entire amount of the aqueous chemical soln. to be supplied may be flowed down or a part thereof may be flowed down into the vapor phase part. The aqueous inorg. chemical soln. includes aqueous solns. of calcium chloride, caustic soda, cyanuric chloride, urea, ammonium chloride, etc.
