Solar-Coal Hybrid for Steam Boiler

Abstract

Solar-coal hybrid is the use of solar and coal energy for producing steam for electricity as opposed to coal alone. The boiler feed-water is pre-heated using solar energy before introduced into the coal boiler, where the steam generating process is finalized for use in the electrical generating turbine. Reviewed is liquid-based direct absorption solar thermal collectors, in which incident sunlight is absorbed directly by the working fluid. Described is the amount of reduction in coal consumption, thus reduction in pollutant.
