A desiccant/steam-injected gas-turbine industrial cogeneration system
An integrated desiccant/steam-injected gas-turbine system was evaluated as an industrial cogenerator for the production of electricity and dry, heated air for product drying applications. The desiccant can be regenerated using the heated, compressed air leaving the compressor. The wet stream leaves the regenerator at a lower temperature than when it entered the desiccant regenerator, but with little loss of energy. The wet stream returns to the combustion chamber of the gas-turbine system after preheating by exchanging heat with the turbine exhaust strewn. Therefore, the desiccant is regenerated virtually energy-free. In the proposed system, the moisture-laden air exiting the desiccant is introduced into the combustion chamber of the gas-turbine power system. This paper discusses various possible design configurations, the impact of increased moisture content on the combustion process, the pressure drop across the desiccant regenerator, and the impact of these factors on the overall performance of the integrated system. A preliminary economic analysis including estimated potential energy savings when the system is used in several drying applications, and equipment and operating costs are also presented.
