Abstract

In the present global scenario, a huge emphasis is laid on efficiency and emissions and with respect to a thermal power plant the condenser is one important auxiliary equipment whose vacuum is one of the critical parameters which is often overlooked and has a vast impact on the plant performance even with a seemingly inconsiderable deviation from the optimum value. The demands placed on utility generating units are very significant and therefore at the Tata Power thermal power plant the purpose of this study was to identify all the factors which affect the condenser performance. With reference to the ideal Carnot heat engine, a lower sink temperature provides for a better work output and therefore the cooling tower performance also plays an integral role and is thus also included in the ambit of this study. The improvements were precisely quantified which occurred after the scheduled maintenance outage. The result of this study provides for methods to achieve better performance and sustainability through certain operational methods and retrofitting, while simultaneously meeting all the demands imposed.
