ENERGY MANAGEMENT IN THERMAL POWER PLANT

INTRODUCTION
Thermal Power Plants are the most important source of power generation. They are based on the Rankine Cycle where high pressure and high temperature steam raised in a boiler is expanded through a steam turbine that drives an electric generator. In a thermal power plant, the chemical energy stored in fossil fuels such as coal, fuel oil, natural gas is converted successively into thermal energy, mechanical energy and finally electrical energy for continuous use and distribution across a wide geographic area. Thermal Power plants have very high availability. Their unplanned or forced outage rates are very low. Thermal Power Plant assets need to be flexible to meet rapidly fluctuating

This project has two objectives. The first objective is to develop a cost-effective liquid desiccant-based dehumidification technology to recover a large fraction of the water present in the plant flue gas. The second objective is to perform an engineering evaluation to determine how such a technology can be integrated to recover water, improve efficiency, and reduce stack emissions of acid gases and carbon dioxide.

Advanced Cooling Technology: This component of the program is focused on research to develop technologies that improve performance and reduce costs associated with wet cooling, dry cooling, and hybrid cooling technologies. In addition, the research area covers innovative methods to control bio-fouling of cooling water intake structures as well as advances in intake structure systems.

Advanced water treatment and Detection Technology: Future controls on the emission of mercury and possibly other trace elements have raised concerns about the ultimate fate of these contaminants once they are removed from the flue gas. In addition, ammonia from selective catalytic reduction systems used to control nitrogen oxide emissions can appear in a power plant’s wastewater streams such as ash sluice water. Research is needed for advanced technologies to detect and remove mercury, arsenic, selenium and other components from the aqueous streams of coal-based power plants should effluent standards be
