Abstract

A dried fuel process brings an efficiency increase and at the same flue gas emission decrease during the process of producing electrical energy in big power stations and heat and power stations that are fired with brown coal or other solid fuels, is achieved by in drying coal or other solid fuel before energetic cycles, mainly before the combustion process, where the water separated from the coal through drying is drained during the cycles. The dried fuel process employs heat obtained directly or indirectly from steam that was used for running the turbine (T). Positive heat is obtained from the steam cooling installation that was used for running the turbine (T). Positive heat is obtained from the steam installation that was used for running the turbine (T), between the turbine (T) and the condenser (S). Positive heat is obtained from the condensate installation between the condenser (S) and the boiler (K). Positive heat is obtained from the cooling system located between the condenser (S) and the cooling tower (CK) or heat exchanger, or water tank. Positively, all foresaid resources can feed the drier at diversified combination. The system for implementing this method by adds a fuel drying system to recently operated power and energy systems relieving humidity from fuel. The drying system is fed with heat obtained directly or indirectly from steam that was used for running the turbine (T).
