Low temperature heat and water recovery fro

< As the flue gas cools, its water content condenses and can be recovered and treated for use within the plant. In general, the results indicate that low temperature waste heat and water recover from boiler flue gas would be more feasible and beneficial for coal plants burning lignite as opposed to higher quality coal. Because these plants

< 2019-9-11 · Types. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation.

< The paper deals with the impact of co-firing biomass with coal in boilers on the dew point of the flue gas. Co-firing of biomass may have twofold implications on corrosion and fouling, which are the processes that determine the lowest acceptable flue gas outlet temperature and as a result, boiler efficiency.

Air heaters and economizers are particularly susceptible to corrosive attack. Other cold-end components, such as the induced draft fan, breeching, and stack, are less frequently problem areas.

The sulfur contained in the fuel is burnt (oxidized) to SO 2 and SO 3, which, at temperatures below the dew point, may lead to the formation of aggressive sulfureous and sulfuric acids.
