Off-design operation of an 900 MW-class power plant with utilization of low temperature heat of flue gases

Abstract

This article presents the o-design operation of a 900 MW-class steam turbine cycle upgraded with utilization of lowtemperaturewaste heat taken from boiler flue gas. The low-temperature heat contributes to increasing the eciency ofpower plants without introducing many complex changes to the whole system. The base for investigations was a powerunit operating in o-design conditions and supplied with steam from a BB–2400 boiler. Modifications to the model weremade using commercially available software and by applying the Stodola equation and the SCC method. Calculationsfor o-design conditions show that, after making some modifications to the system, both heat and electricity generationcould be increased through the addition of a low-temperature heat exchanger.
