Abstract


A process for dust removal coupling heat recovery of the flue gases of sugar mill boilers is put forwards. A dust scrubber coupling with heat recovery from the flue gases was devised. The devise was basically a plate heat exchanger in which atomized hot water was spayed in the flue gas channels. A pilot test was carried out in a sugar mill to preliminarily investigate the performance of heat recovery and dust removal. The results shown that the heat exchange rate was significant, the dust removal rate for particles under 10μm in diameter was between 70-85%, and the emitted dust concentration was about 30~40 mg/Nm3.
