Exhaust Emission Testing

Exhaust emission testing has become increasingly important to both manufacturers and operators of any form of equipment relying on the combustion of fossil fuels as exhaust emission limits are reduced and fines for non compliance increased.

HGL Dynamics has good knowledge of the requirements of turbine exhaust emission testing and extensive experience within the industrial turbine marketplace. This enables HGL to provide support for your emission testing requirements, including tests operation and monitoring and system maintenance / fault finding.

There are a number of test methods approved depending on the equipment location. Emission limits also vary being set by the appropriate National or Local Government. For Europe the standards are general EN or ISO and for North America the standards are set by the EPA

 The process of burning natural gas, diesel fuel, LCV, MCV (low/medium calorific value)  or bio-fuel in a turbine (or any other combustion system) produces  pollutants, the legislation sets limits that may not be exceeded

The following components have regulated emission levels due to their effects on the atmosphere;

  • Nitrogen oxides (NOx)
  • Total hydrocarbon (THC)
  • Carbon monoxide (CO)
  • Particulate matter (PM10)
  • Carbon Dioxide

HGL staff have knowledge and experience in performing such tests within major OEM turbine manufacturers, including:

  • measuring low levels of NOx & CO, hydrocarbons and carbon dioxide
  • ambient air testing & gas chromatography.
  • Gas turbine inlet measurements
  • Gas turbine exhaust measurements
  • Gas chromatography
  • Emissions fault finding
  • System audits
