T/CSEE 0295-2022 Guidelines for Safety Pre-evaluation of Thermal Replacement of the Side-pass Heating System of a Power Plant
Basic Information
Scope
Main technical content: This document specifies the procedures, contents, and basic requirements for the safety pre-evaluation of bypass heating modification projects in thermal power plants. This document is applicable to the safety pre-evaluation of bypass heating modification projects in thermal power plants. This document is applicable to various types of bypass heating modification projects that use the existing bypass system of steam turbines or new steam de-superheating and pressure-reducing systems for heating, including but not limited to direct steam de-superheating and pressure-reducing heating of main steam, direct steam de-superheating and pressure-reducing heating of reheated steam, direct steam de-superheating and pressure-reducing heating of cooled reheated steam, and bypass heating modification projects that add or utilize the existing low-pressure bypass heating or add or utilize the existing high- and low-pressure two-stage bypass heating systems for heating
