Full title and description

ASME PTC 30.1 — Air‑Cooled Steam Condensers. Performance Test Code that provides uniform test methods for conducting and reporting thermal performance characteristics of mechanical‑draft air‑cooled steam condensers (ACC) operating under vacuum conditions; includes rules for acceptance testing, routine monitoring, and post‑test uncertainty analysis.

Abstract

ASME PTC 30.1 establishes standardized procedures and measurement methods to determine the thermal performance and steam‑flow capability of air‑cooled steam condensers, including guidance for acceptance tests, routine tests, and uncertainty analysis. The Code is intended to support contractual acceptance and guarantees (for example steam flow or turbine backpressure and fan power guarantees) and to ensure results of the highest practical accuracy while describing equipment and test exclusions.

Scope

Specifies test procedures, instrumentation, measurement methods, calculation techniques, and uncertainty analysis for mechanical‑draft air‑cooled steam condensers operating under vacuum. The Code covers determination of steam flow capability (or deviations from design flow/turbine backpressure) and procedures for assessing dissolved oxygen and condensate temperature. It explicitly excludes equipment where process fluid is above atmospheric pressure, non‑steam process fluids, single‑phase process fluids, wet‑surface ACCs, natural‑draft or fan‑assisted air‑cooled condensers, and air‑cooled condensers with inlet air conditioning in service. The Code is intended for use in acceptance testing and contractual performance verification.

Key topics and requirements

• Standardized acceptance test procedures for mechanical‑draft air‑cooled steam condensers.
• Detailed measurement methods for thermal performance, steam flow capability, turbine backpressure, and fan power.
• Guidance for routine monitoring and re‑testing to track performance over time.
• Required post‑test uncertainty analysis and criteria for considering a test an ASME Performance Code Test.
• Procedures to assess dissolved oxygen and condensate temperature where specified.
• Explicit exclusions (e.g., wet‑surface ACCs, inlet air conditioning, non‑steam fluids, above‑atmospheric process fluids).

These topics and requirements are set to produce high‑accuracy, repeatable results suitable for contractual acceptance and performance guarantees.

Typical use and users

Used by equipment and systems test engineers, instrument engineers, plant and power engineers, steam‑turbine manufacturers, A/E firms, instrument manufacturers, and third‑party testing agencies for acceptance testing, warranty verification, commissioning, and routine performance monitoring of air‑cooled steam condensers in electric‑utility, industrial, and process plants.

Q: What does it cover?

A: It covers procedures, instrumentation, measurement and calculation methods, reporting requirements, and required uncertainty analysis for acceptance and routine tests of air‑cooled steam condensers operating under vacuum; it also lists specific exclusions (e.g., wet‑surface ACCs, above‑atmospheric fluids, inlet air conditioning in service).

Q: Who typically uses it?

A: Test engineers, instrument engineers, plant and power engineers, turbine and condenser manufacturers, A/E firms, and independent testing organizations involved in acceptance testing, commissioning, warranty verification, and performance monitoring.
