Lignite is an important and affordable fuel for power generation. The problem is its high moisture content. Hot flue gas can be used to dry the wet incoming lignite in conventional lignite-fired power plants but this reduces thermal efficiency and so increases CO 2 emissions. Moisture vapour in the flue gas also means a larger boiler furnace is needed which increases …
