Abstract
This paper is a actual design case applied to make a bid for CHP plant construction in some country. The purpose of this study is to optimize the system performance for the requirement conditions written in ITB by the client. The system consists of gas turbine, steam turbine, heat recovery steam generator and heat exchangers for district heating. The performance analysis is conducted for various seasons conditions and heat load. As a result, air density and heat load is reduced in accordance with decreasing of the outdoor temperature, therefore the system power is reduced. Considering this, the design parameters to meet the requriement conditions are optimized.
