Waste heat recovery from flue gases with substantial dust ...

Sep 01 1999 · The flue gases with temperatures between 280 and 450°C contain substantial amounts of dust and have to be quenched in a gas conditioning tower by complete evaporation of water before leading the gases to the bag filter or to ESP. Scarcity of electric power and world wide efforts to reduce the atmospheric CO 2 demands heat recovery from flue gases for power generation.

Bag Filter in Boilers & Bag filters Working Principle ...

This pressurized air enters through the opening from where the Flue gases leave the Filter Bag and this air being pressurized hits the inner surface of the Filter Bag. The dust particles being at rest gets separated thereby justifying the law of inertia. These dust particles thus separated gets collected at the bottom bit of the Bag Filter with the help of a Rotary Air-Lock valve. Thereby completing the operation.

Semi-Dry Flue Gas Desulfurization

The CFB FGD system requires a filter for solids recirculation and dust removal. If it is possible to use the desulphurisation product in conjunction with the fly ash of the boiler then there is no need to remove the dust upstream of the CFB FGD. If the boiler ash is marketed separately the flue gas dust is removed in the existing filter.
