Abstract
A process and apparatus for heating gas in which a flow rate D0 of a warm fluid is caused in an input line, connected at its upstream portion to a source of warm fluid and at its downstream portion to the inlet of one of the passages of a heat exchanger; a portion of the flow D0 is diverted before it reaches the inlet of the first passage, into a branch line connected at its upstream portion to a so-called primary point of the inlet line located between the source of warm fluid and the inlet of the first passage; the gas to be heated is caused to circulate in another passage of the exchanger, so as to effect heat exchange between the gas to be heated and the warm fluid, thereby to obtain at the outlet of the second passage a warmed gas, and at the outlet of the first passage, a cooled warm fluid; the temperature of the warmed gas is controlled by the aid of a flow rate regulating valve located in a selected position in the inlet or outlet line.
