ASME PTC 47.4 – 2015: Power Block of an Integrated Gasification Combined Cycle Power Plant

The object of this Code is to provide uniform test methods and procedures for the determination of the thermal performance and electrical output of an integrated gasification combined cycle (IGCC) power block. This Code applies to combined cycle power plants (power blocks) that operate in conjunction with a gasification plant, an IGCC power plant, or an IGCC cogeneration plant. This Code does not apply to power blocks other than those associated with IGCC plants. This Code is applicable to the combined cycle power block of IGCC power plants, whereas ASME PTC 46 is applicable to conventional combined cycles. The thermal streams and corrections in ASME PTC 46 for conventional combined cycles are normally limited to gas or liquid hydrocarbon fuel input and steam or water input. In ASME PTC 47.4, test measurements and associated corrections are needed to address multiple thermal streams such as heated hydrocarbon syngas fuel input, water and steam inputs from gasification process units, nitrogen input from the air separation plant, and air extraction to the air separation plant. Emissions tests, operational demonstration tests, and reliability tests are outside the scope of this Code.
