34、rformance of dust collecting equipment depends on the physical and chemical properties of the flue gas and the particles in the flue gas. The choice of equipment is therefore dependent on these properties and the pollution reguiations to be met. Wet removal systems are not normally used to extract t
35、he large quantities of dust in electricim generating stations because of difficulties in the dtsposal of the sludge, treatment of the waste water and lowering of the flue gas discharge temperature. If they are offered, the extent of supply should normally include waste water tmtrnent plant and propo
