Title: Multi-cyclone dust extractor for flue gases - uses heat exchangers in common raw and clean gas chambers
Inventor: PROCHNOW KARL-WILHELM
IPC: F28D21/00
Filed: 1980-03-11
Abstract: A multicyclone dust extraction plant for flue gases has a common crude gas inlet chamber for all cyclones. Heat exchanges are arranged in these chambers for the passage of a heat transfer medium to cool the gases before a blower takes them to a chimney. This prevents damage to the chimney lining by excessively high temps. and utilises the otherwise wasted heat energy of the flue gases. Specifically a bank of six cyclones receives the flue gases from the dust laden gas chamber. The clean gas leaves through the central tube and passes through a common clean gas chamber before the blower with the motor drive takes it to the chimney through pipe. Both chambers contain tubular heat exchangers with fins on their tubes and with flap valves so that they can be by-passed.
