Concept of a system for waste heat recovery from flue gases in a coal-fired power plant

The paper presents an analysis of methods of recovery and utilization of waste heat from flue gases of power units in coal-fired power plants in Poland and worldwide. Systems for waste heat recovery from flue gases and methods of utilizing the waste heat in Polish coal-fired power plants were described. An analysis showing advantages and disadvantages of the heat recovery systems currently in use was been performed. A concept of waste heat recovery and utilization with condensation of the steam contained in flue gases was proposed. This concept is characterized by a larger stream of the recovered waste heat as compared with the methods without condensation.
