ISO 21905 discusses gas turbine exhaust systems with or without heat recovery. ISO 21905 specifies requirements and gives recommendations for the design, materials of construction, modelling, controlling, fabrication, inspection, testing, installation, start-up and operation of industrial gas turbine (GT) exhaust systems with or without waste heat recovery unit (WHRU). Gas turbines can be on-shore or off-shore for such sectors as oil and gas, chemical and process industries, utilities, or other intensive energy users.
For ISO 21905, the exhaust system means all items in the turbine exhaust gas stream between the GT exhaust gas collector outlet flange and the termination/s to the atmosphere.
The following items are not covered by ISO 21905:
ISO 21905 on gas turbine exhaust system is relevant to:
An exhaust gas turbine drives a turbocharger with power from a piston engine. ISO 21905aims to provide purchasers and suppliers of exhaust duct systems with an overview of the use of CFD assessment in improving exhaust duct design and quality assurance.
ISO 21905 instructs buyers to include datasheets, checklists, and other applicable information in their enquiries.
Suppliers and purchasers will benefit from ISO 21905 to which equipment can be bought, designed, and constructed - especially given the challenging nature of turbulent exhaust gas flow and the associated complexity of the mechanical design.
