GENERATOR, TURBINE AND THERMAL EFFICIENCY OF LUMUT BALAI GEOTHERMAL POWER PLANT

Abstract

Lumut Balai Geothermal Power Plant is a single flash plant which take high-pressure hot water from the reservoir into the lowpressure tank then using the resulting steam to turn the turbine. After turning the steam turbine condensed using a direct contact condenser before injection back into the reinjection wells, the condensation process is assisted by using Cooling Tower as Recirculating Cooling Water. During the operation, it is fundamental to calculate the efficiency of plant parameters to manage the production reliability in Lumut Balai geothermal field. Based on the integrated formulation during daily monitoring, there can be concluded that Lumut Balai Geothermal Power Plant has thermal efficiency is 2.35%, generator efficiency of about 84.39%, and turbine efficiency is 85%.
