DESCRIPTION

BS ISO 11042-2:1996


This standard BS ISO 11042-2:1996 Gas turbines. Exhaust gas emission is classified in these ICS categories:
  • 27.040 Gas and steam turbines. Steam engines
  • 13.040.40 Stationary source emissions

This part of ISO 11042 establishes the monitoring programme and the requirements for the selection and operation of hardware to be used for continuous measurement over an extended, not limited, time. The concentration and absolute magnitude of specified emissions in the exhaust gas are monitored as well as related gaseous components from gas turbines together with essential operating conditions. Appropriate terms and symbols in addition to those defined in ISO 11042-1 are used. It presents requirements for the monitoring environment, the instrumentation and recording as well as for quality assessment and correction of data.

This part of ISO 11042 is applicable for all gas turbines producing mechanical shaft power and/or which are used as drivers for electrical generation as well as marine application but excluding application in aircraft. It can be used as a basis for installations equipped to utilize exhaust heat.

This part of ISO 11042 is applicable for gas turbines which utilize the open cycle process. It is also applicable as a basis for gas turbines which utilize the semi-closed cycle and for gas turbines equipped with free piston compressors or with special heat sources.

This part of ISO 11042 is not intended to be used for acceptance testing for gas turbine exhaust emissions except by mutual agreement between the parties involved.

Constituents, which are released into the air in significant quantities, greater than a certain limiting value, should be monitored. Such values are determined by mutual agreement between the parties involved.

In general, this part of ISO 11042 requires that the following parameters be continuously monitored: emissions, diluent gas (O2, CO2), exhaust gas flow (calculated or, if required, measured), fuel consumption and gas turbine plant performance. Chemical analysis of the fuel is required on fuel samples taken at regular intervals.
