本规范旨在提供统一的测试方法和程序，以确定综合气化联合循环（IGCC）发电机组的热性能和电输出。本规范适用于与气化厂、IGCC发电厂或IGCC热电联产厂联合运行的联合循环发电厂（发电机组）。本规范不适用于与IGCC电厂相关的发电机组以外的发电机组。本规范适用于IGCC电厂的联合循环发电机组，而ASME PTC 46适用于常规联合循环。ASME PTC 46中用于常规联合循环的热流和校正通常限于气体或液体烃燃料输入和蒸汽或水输入。 在ASME PTC 47.4中，需要进行测试测量和相关修正，以解决多种热流问题，如加热的碳氢化合物合成气燃料输入、来自气化工艺装置的水和蒸汽输入、来自空气分离装置的氮气输入以及空气分离装置中的空气抽取，可靠性测试不在本规范的范围内。

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.
