Abstract

An apparatus for thermal exhaust gas purification includes at least one thermal reactor to which a raw gas to be purified is supplied and in which the supplied raw gas is thermally purified, and an energy recovery apparatus to which a gas purified in the thermal reactor is supplied via at least one outlet line. For improving the balance of energy, it is proposed that the energy recovery apparatus includes at least one condensation heat exchanger in which the purified gas is cooled down such that condensable substances contained in the purified gas condense, and enthalpies released thereby are transmitted to a heat exchange medium and/or the raw gas upstream of the thermal reactor.
