Description

This document, “Guideline for Performance Evaluation of Heat Recovery Steam Generating Equipment”, published by the American Boiler Manufacturers Association (ABMA), establishes industry-standard procedures for testing and evaluating the performance of Heat Recovery Steam Generators (HRSGs) used with gas turbines and other exhaust heat sources. The guideline details methodologies for measuring steam generation, gas-side pressure losses, and steam purity, while outlining requirements for instrumentation, calibration, data collection, test validity, and correction of test results to agreed operating conditions. It provides detailed procedures for conducting heat and mass balance calculations, determining exhaust gas flow, accounting for ambient operating conditions, and validating test accuracy. The document also includes sample calculations, data collection forms, and reference methods to help engineers, operators, manufacturers, and owners verify that HRSG equipment meets specified performance guarantees and operates efficiently under real-world conditions.
