ASME PTC 19.11 is a vital resource for a wide range of professionals involved in the design, operation, and maintenance of thermal power plants, including:
Extracting a sample that accurately reflects the true chemical composition of the process fluid. including requirements for isokinetic sample probes
ASME PTC 19.11-2008 (R2018) provides essential guidelines for sampling, conditioning, and analyzing steam and water in power cycles to ensure accurate chemical analysis and prevent boiler/turbine damage. It covers the full sampling process, including requirements for isokinetic sample probes, cooling systems, and analysis methods for parameters like pH and conductivity. You can purchase the official document on the ASME website.

The primary objective of this code is to specify the methods and instrumentation required for testing boiler makeup, feedwater, steam, and condensate. It ensures that contamination levels are at or below specified maximums before performance tests on turbines, condensers, or deaerators are conducted. Key areas covered in the standard include:
The framework of ASME PTC 19.11 revolves around three primary operational goals:
