Claim:
1. An apparatus for the treatment of gases, the apparatus comprising: a heat-insulated protective housing; a stratified reservoir disposed in said heat-insulated protective housing and configured for accommodating and storing therein a stratified reservoir liquid in superposed layers in a plurality of temperature zones having mutually different temperatures and including a cold temperature zone and a high temperature zone; an outer heat exchanger disposed outside said heat-insulated protective housing and fluidically communicating with said stratified reservoir through a stratified reservoir liquid branch line connected to said cold temperature zone of said stratified reservoir, wherein ambient air flows around said outer heat exchanger as a heating medium for heating a defined quantity of cold stratified reservoir liquid drawn off from said cold temperature zone of said stratified reservoir, and wherein the cold stratified reservoir liquid, which has a lower temperature than the ambient air, is heated by heat exchange with the ambient air to form a hot stratified reservoir liquid at a defined stratified reservoir liquid temperature; a stratified reservoir liquid metering line disposed to conduct the hot stratified reservoir liquid from said outer heat exchanger back to said stratified reservoir into said high temperature zone; an inner heat exchanger disposed inside said heat-insulated protective housing and conducting therethrough a defined quantity of a gas to be heated, received from a gas feed line, and a defined quantity of hot stratified reservoir liquid drawn off from said high temperature zone of said stratified reservoir, received through a stratified reservoir liquid feed line, wherein the gas, which has a lower temperature than the hot stratified reservoir liquid, is heated to form heated gas at a defined gas temperature while the hot stratified reservoir liquid is cooled to form cooled stratified reservoir liquid; a stratified reservoir liquid recirculation line connected to conduct the cooled stratified reservoir liquid from said inner heat exchanger to said stratified reservoir into said cold temperature zone, and a gas discharge line connected to conduct the heated gas away from said inner heat exchanger; and a gas analysis apparatus connected to said gas discharge line for receiving the heated gas.
