Chimney permitting smoke heat use - has rustless steel tube, pref. led into heat exchanger

摘要

The chimney is esp. for use where smoke temps. are lowered below condensation point in follow-up heat-exchangers. The brick structure of the chimney contains a tube made of rust-free steel. This is pref. carried into the heat-exchanger utilising smoke heat, at least to the verge of the condensation point. The heat-exchanger pipe system carrying smoke away may be made of rust-free steel. This makes it practicable to exploit the difference in temp. between smoke and the environment, for heating purposes.
