The present invention harvests and utilizes fluidized bed drying technology and waste heat streams augmented by other available heat sources to dry feedstock or fuel. This method is useful in many industries, including coal-fired power plants. Coal is dried using the present invention before it goes to coal pulverizers and on to the furnace / boiler arrangement. Coal can be intercepted on current coal feed systems ahead of the pulverizers. Drying fuel, such as coal, is done to improve boiler efficiency and reduce emissions. A two-stage bed utilized in the process first “pre-dries and separates” the feed stream into desirable and undesirable feedstock. Then, it incrementally dries and segregates fluidizable and non-fluidizable material from the product stream. This is all completed in a low-temperature, open-air system. Elevation of fan room air temperature is also accomplished using waste heat, thereby making available to the plant system higher temperature media to enhance the feedstock drying process.

Systems and methods for improving the efficiency of a power generation facility utilize heat energy to preheat inlet-air that is supplied to the compressor of a turbine or to preheat fuel that is burned in the turbine. The heat energy used to preheat the inlet-air can be drawn from a heat recovery steam generator (HRSG) that produces steam using at least part of the exhaust gas of the turbine. The heat energy can be obtained from one or more predetermined points within the HRSG, such as a feed water line exiting a drum of the HRSG or a feed line connecting an economizer of the HRSG to a drum of the HRSG. The fluid drawn from the predetermined point passes through a heat exchanger or a preheater to remove the heat energy used for preheating. The fluid is then returned to the HRSG immediately downstream from the point from which it was drawn.
