NOVELTY - Operating (M1) electricity generation plant arranged to burn biomass fuel, the plant including boiler (10) for producing steam, condensing steam turbine (53), air-cooled vacuum condenser (55), flue gas moisture condensing arrangement (17), and collection for condensate from flue gas moisture condensing arrangement, in which method involves controlling quantity of condensate from flue gas moisture condensing arrangement to fulfill water demand of plant by combination of condensed steam from turbine and condensate from flue gas moisture condensing arrangement.    USE - For operating electricity generation plant arranged to burn biomass fuel (claimed).    ADVANTAGE - The method makes it possible to locate the plant at a site where there is very limited water resources, or where the discharge of water from the plant is unacceptable. In addition, by making the plant wholly self-sufficient so far as the water demand is concerned, the flue gas moisture condensing arrangement also has the ability to increase the overall efficiency of the plant, by utilizing heat from the flue gases which otherwise would be wasted, through discharge of hot flue gases to atmosphere. The use of a condensing economizer allows heat extracted from the first stage to be used to provide thermal energy to ancillaries associated with the plant, thus reduces the demand of ancillaries for steam originating from the boiler.
