Coal and biomass are co-combusted in boilers that have been designed to burn coal. For this purpose, the existing coal power plant has to be partly reconstructed and retrofitted. Co-firing is an option to convert biomass to electricity, in an efficient and clean way, and to reduce GHG emissions of the power plant. Co-firing processes

The power plant was a simple design that used the plentiful English coal to power a steam turbine. The turbine would turn and output electricity that could then be transferred to nearby locations. It is a design that is still the basis of many power plants today.
New Delhi: Announcements and pledges made at the just concluded Glasgow climate summit (COP26) will directly impact 80 per cent of planned coal-fired power plants around the world, an analysis said on Wednesday. With several net zero pledges announced, 95 per cent of the existing global coal power fleet is committed to carbon neutrality.
Introduction. Flue gas desulfurization (FGD) is the removal process of sulfur dioxide (SO2) from flue gases. Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.
