Facility Summary
The facility includes two M501F gas turbine generators installed indoors, which are able to burn natural gas and diesel oil with DLN (Dry Low NOx) combustors. The triple-pressure heat recovery steam generators are of the reheat type with natural circulation designs.The plant is a 2-in-1 configuration with two gas turbines connected to their respective HRSGs, and with the steam from both HRGSs supplied to a steam turbine. An Air Cooled Condenser has been provided as the cooling system of the turbine exhaust steam flow, owing to the insufficient cooling water supply on-site. The gas turbine operations are monitored by MHI in Japan using Remote Monitoring System to ensure proper operation and to maintain a higher availability of units.
