Method and apparatus for reheating of cleaned gases subsequent to wet cleaning of raw gases. Cooled cleaned gases of high humidity which have been subjected to a wet cleaning process are reheated by means of regenerative heat exchange with as yet uncleaned, hotter raw gases, a previously already heated partial flow of cleaned gas being added to the cleaned gas flow prior to the performance of the regenerative heat exchanger. The partial flow of cleaned gas is diverted from the previously wet-cleaned total flow of cleaned gas, prior to the regenerative reheating of the cleaned gases by means of heat energy withdrawn from the raw gases, is increased in pressure, and is heated, separately from the main flow of the cleaned gases, in a regenerative heat exchange with the raw gases.

A method for reheating of cleaned gases subsequent to the wet cleaning of raw gases by means of heat exchange between said raw and cleaned gases in a regenerative heat exchanger, comprising the steps of: prior to the regenerative reheating of the cleaned gases by means of heat energy withdrawn from the raw gases, diverting from the previously wet-cleaned total flow of cleaned gases a partial flow of cleaned gases; increasing the pressure of the partial flow of cleaned gases to exceed that of the raw gases in said regenerative heat exchanger; heating said partial flow of cleaned gases in the regenerative heat exchanger and disposing the partial flow of cleaned gases therein so as to prevent an overflow of raw gases into the cleaned gases during the regenerative heat exchange step; and adding the reheated partial flow of cleaned gases to the total flow of cleaned gases upstream of the regenerative heat exchanger.
