Capital Cost

← Previous | Next →

This is a standard capital cost result screen. It is available for both the NGCC and IGCC plant types.

The following process area costs are displayed:

•Gas Turbine: The capital cost of the gas turbines, the air compressor, and the combustor.

•Heat Recovery Steam Generator: The heat recovery steam generator (HRSG) is a set of heat exchangers in which heat is removed from the gas turbine exhaust gas to generate steam for the steam turbine.

•Steam Turbine: The cost of a steam turbine depends on the mass flow rate of steam through the turbine, the pressures in each stage, and the generator output.

•HRSG Feedwater System: The boiler feedwater system consists of equipment for handling raw water and polished water in the steam cycle, including a water mineralization unit for raw water, a demineralized water storage tank, a condensate water, a condensate polishing unit, and a blowdown flash drum.
