Description

This Code provides procedures for performance testing of integrated gasification combined cycle (IGCC) power plants to determine fuel gas flow and quality, energy efficiency, heat rate, and power output at specified operating conditions. It also provides procedures to determine the flow and quality of cleaned fuel gas produced by the IGCC plant. This Code covers a defined range of primary fuel characteristics, but is limited to combined-cycle, power generation systems using gas and steam turbines. This Code defines the boundaries of the overall IGCC power plant to encompass three major plant sections — the air separation unit (ASU, for oxygen-blown gasifiers or plants that use nitrogen), the gasification process (including gas cleanup), and the power block. ASME PTC 47 is part of a series comprised of five PTCs that describe testing procedures for an integrated gasification combined cycle (IGCC) power plant: PTC 47 PTC on Integrated Gasification Combined Cycle Plants PTC 47.1– Cryogenic Air Separation Unit of an IGCC Power Plant PTC 47.2 – Gasification Block of an IGCC Power Plant PTC 47.3 (to be released) – Syngas Conditioning Block of an IGCC Power Plant PTC 47.4– Power Block of an IGCC Power Plant
