ABSTRACT:
Fuel and additional material are dried prior to entering the combustion chamber of a thermal power plant using drying chambers having fluidized beds. The heat required for drying is extracted from the hot ashes from the power plant by means of an oxygen-poor gas which circulates through heating chambers containing the ashes and drying chambers containing the fuel in a substantially closed loop. The loop may include a condenser for dehumidification of the circulating gas.
