In　lignite-tired　power　plants,　the　high　water　content　of　lignite　(35-40%)　is　responsible　for　significant　reductions　in　boiler　efficiency　due　to　the　large　amounts　of　heat　loss　experienced　through　water　evaporation　during　coal　combustion.　Installation　of　a　water　condensation　device　in　the　outlet　of　the　desulfurization　absorption　tower　can　recover　substantial　amounts　of　water　and　latent　heat　from　the　flue　gas　that　containing　saturated　steam.　In　the　present　study,　a　pilot　test　platforni　was　built　into　a　600MW　lignite-fired　power　plant,　and　a　50,000m(3)/h　flue　gas　flow　was　been　extracted　and　cooled　by　5　degrees　Cduring　the　test.　Using　our　theoretical　model　for　this　energy　efficiency　innovation,　the　test　results　demonstrate　that　129.5GJ/h　of　latent　heat　can　be　recovered　and　61.6t/h　condensate　water　can　be　collected　from　the　flue　gas　(2,500,000m(3)/h)　for　the600MWlignite-tired　power　plant.　The　wet　flue　gas　desulphurization　system　(wet　FGD)　consumes　the　supplemental　water　of　60-80　t/h　for　this　power　plant.　Consequently,　the　water　recovery　quantity　of　73　fah　demonstrate　that　zero　net　water　consumption　can　be　achieved　by　returning　the　recovered　water　back　into　wet　LCD.　(C)　2014　The　Authors.　Published　by　Elsevier　Ltd.
