Application of gas systems to gas turbines and supplementary and auxiliary fired burners

scope:

This Standard covers the essential safety aspects of the engineering, start-up, operation, and shut-down of gas turbines and associated equipment (typical arrangements are shown in Figures 2 and 3). They are not intended to provide a complete specification for such equipment.

This Standard refers primarily to gas turbines using lighter and heavier-than-air flammable fuel gases such as Manufactured Gas, Natural Gas (NG), Liquefied Petroleum Gas (LPG), and LPG/air mixtures (1st, 2nd and 3rd family gases are further defined in BS 1179 (withdrawn)). They may be appropriate for other non-conventional gases such as Landfill, Anaerobic Digester, and Mines Recovery Gas and Hydrogen, but the particular characteristics of the gas need to be recognised with respect to consequent effects on materials and operations.

This Standard applies to gas turbines for continuous and standby duties, for example in industrial and commercial sites for combined heat and power (CHP), power generation, and gas compression systems.

Turbines used for vehicular propulsion or used offshore are not covered. However, the general principles outlined in this Standard may be used as guidance.

This Standard applies to:

• both single and multi-shaft turbine types

Note: In this context, "shaft" relates to the turbine and not to the alternator. The term "spool" is a commonly used alternative.

• both single and multiple burner types

• turbines exhausting to heat recovery equipment, with or without supplementary and/or auxiliary-fired burners, which may or may not have air supplies other than the engine exhaust. Those having independent air supplies are also considered as auxiliary fired.

This Standard applies to gas turbines supplied directly from a gas supply and to those supplied via a gas compressor.

Note: Requirements for gas compressors are provided in IGEM/UP/6.

Metric standard conditions apply, unless otherwise specified.

All pressures are gauge pressures, unless otherwise stated.

All fuel inputs are given net, unless otherwise stated.

The term "turbine(s)" refers to "gas turbine(s)" throughout, unless otherwise stated.

Italicised text is informative and does not represent formal requirements.

Appendices are informative and do not represent formal requirements unless specifically referenced in the main sections via the prescriptive terms "must", "shall" or "should".
