An Analysis of Solar Thermal Plant with Direct Steam Generation

Abstract

Solar Thermal Power Plant Technology, also known as Concentrated Solar Power Plants (CSP), is gaining popularity due to its low cost as compared to other technologies. There are numerous technologies in CSP, however, Direct Steam Generation (DSG) is selected for fabrication cost. A study of small power generation using the said technology is studied for producing 40 W by changing various parameters. A detailed mathematical model is described for optimum selection of boiler (saturated section), super heater along with their corresponding heat losses. Mathematical calculations are further extended for bare and glasscovered tube. Analysis is performed on the basis of different Nusselt and Reynolds Number. For an open cycle, it is concluded that glasstube design is more efficient.
