Scope
This document specifies the safety requirements for open-cycle (simple, combined, heat recovery, reheating, etc.) aero-derived and industrial gas turbines (hereinafter referred to as "gas turbines") using liquid or gaseous fuels, used on land and at sea, including floating platforms, as well as safety-related control and detection systems and necessary auxiliary facilities.
This document applies to mechanical, electrical, and pressure equipment components and systems of gas turbines, including but not limited to auxiliary gearboxes, load gearboxes, combustion systems, air filtration, gas turbine control, oil systems, and fuel systems. It also covers safety risks during installation, such as exhaust purging or draining.
This document details the anticipated major hazards associated with aero-derived and industrial gas turbines and outlines preventive measures and processes to reduce or eliminate these hazards. It addresses harm to human health and environmental damage. Equipment damage unrelated to human health or environmental hazards is not covered.
The purpose of this document is to ensure that the design, manufacture, and operation and maintenance of equipment throughout its service life comply with GB/T 15706–2012.
This document, to the greatest extent possible, specifies the safety requirements for gas turbines from an international perspective based on existing certified ISO and IEC standards. For aspects not covered by ISO or IEC standards, other specifications or standards (such as EN, NFPA, etc.) are used.
This document does not include the minimum level of functional safety, which is determined based on the application and site.
This document does not apply to the following items, but when necessary, it can be used as a general guide for these equipment:
——Design of exhaust system structure;
——Driven equipment;
——Micro gas turbines covered by GB/T 38180–2019;
——Gas turbin
