Abstract (en)
[origin: EP0708298A2] The process includes an afterburning of the flue gas which is fed into an afterburning chamber with admixture of a secondary air. The primary flue discharge (14) takes place from a deep point of the combustion chamber. Flue gases are added to the primary flue gas from a higher secondary flue discharge (15) during its flow into the afterburning chamber (13) via a first flue gas return duct (11). Pref. the admixture of the flue gases (4) of the first return duct and of the secondary air (5) into the primary flue gas is carried out by exhausting such that the primary flue gas passes through a nozzle system, prior to reaching the afterburning chamber.
