ASME PTC 47 – Integrated Gasification Combined Cycle Power Generation Plants

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. Tests conducted by this Code determine the quantity and quality of fuel gas by its flow, temperature, pressure, composition, heating value, and its content of contaminants. Contaminants are compounds that are potentially deleterious to the gas turbine and power block in general, or are precursors to stack emissions. Contaminants to be measured are sodium (Na), potassium (K), vanadium (V), lead (Pb), calcium (Ca), barium (Ba), manganese (Mn), phosphorus (P), sulfur compounds (H2S and COS), nitrogen compounds (HCN and NH3), chlorine compounds (HCl), and particulate matter.
Recommendations are included for the following in pretest agreements: testing procedures, types of instruments, methods of measurement, methods of calculation, and contents of test reports.
Regulatory compliance testing of IGCC power plants is not covered by this Code.
