<p>PURPOSE:To miniaturize a reheating system for treated gas, by a method wherein two liquid thermal mediums are applied as a heat accumulating body and the two liquid thermal mediums each are made to exchange their heat indirectly after heat has been exchanged directly between untreated gas and treated gas. CONSTITUTION:High temperature untreated gas 1 touches directly a No.1 low temperature thermal medium 31 in a No.1 thermal medium contactor 11, the high temperature untreated gas 1 is turned into a low temperature untreated gas 1' through a temperature decrease and the No.1 low temperature medium 31 is turned into a No.1 high temperature medium 31' through a temperature rise. The No.1 high temperature thermal medium 31' led to an indirect heat exchanger 20 is exchanged its heat with that of a No.2 low temperature thermal medium 32 and No.1 high temperature medium 31' is turned into the No.1 low temperature medium 31 through the temperature decrease. On the other hand, the No.2 low temperature thermal medium 32 is turned into a No.2 high tem perature thermal medium 32' through the temperature rise. With this, it is possible to obtain a heat recovery and reheating method which is compact and free of gas leak.</p> |
