Economic System Operation Considering Valve Throttling Losses I-Method Computing Valve-Loop Heat Rates on Multivalve Turbines

Abstract

The heat rate characteristics of reheat and nonreheat machines, including a rigorous treatment of throttling, must be obtained prior to an investigation of savings made possible by reducing throttling losses. The purpose of this paper is to describe an analytical method and an associated computer program for calculating the heat rate valve loops for multivalve nonreheat and reheat machines.
