Comparison Between Heat Pipes Based Condenser and Conventional Condenser of Power Plant

摘要

Condenser is a vital part in the steam circuit of power plant. But since inception there wre no modifications in the design of this vital component. The only variations are, the type of nonferrous tubes and tube matrix according load on the condenser. In this paper design modification of condenser suggested viz. type heat transfer utilized in the condenser. Two phase heat transfer suggested instead single heat phase heat transfer as in conventional condenser. This type of two phase heat transfer achieved by using heat pipes. The heat pipe designed for this special application of steam condensation. A laboratory model of condenser with 16 heat pipes fabricated and experiments were conducted on this heat pipe based condenser. The comparison of the performances of conventional condenser made of simple copper tubes and heat pipe based condenser were presented in this paper. Effectiveness calculations, heat transfer surface area comparison, comparison of exergy analysis for the both type of condenser presented in this paper. The comparative study reveals that the heat pipe based condenser had much improved performance parameters over the condenser made up with copper tubes.
