Using Portable Emissions Analyzers for Optimizing the Performance of a Cogeneration Plant

Application Note #IA-13-0801

Cogeneration, or combined heat & power (CHP), is the utilization of boilers, turbines, and/or engines to simultaneously generate electricity power and heat that can be useful in several ways such as for hot water, steam, district heating, and water desalination.

Some types of cogeneration process applications include the following:

  • Industrial Processes – Power Plants, Refineries, Chemical Plants, Food & Beverage, Pharmaceutical
  • Waste Incineration & Management – Industrial, Municipal, Medical & Hospital, Landfills
  • Burning Biomass – Pulp & Paper Plants, Saw Mills, Sugar Mills, Peat & Wood Waste
  • Institutional – Schools, College Campuses, Prisons, Hospital


Optimizing the overall performance of a cogeneration plant for fuel savings, combustion efficiency, maintenance, safety, and emissions reduction purposes can be done by using a portable emissions analyzer to monitor important parameters at many different locations in the CHP plant including the following:

  • Flue Gas Temperature
  • O2, CO, & CO2
  • CxHy Hydrocarbons
  • Total NOx (NO + NO2)
  • SO2 for SOx
  • H2S

Instrument Solution

The E8500 Plus portable emissions analyzer can easily be used for accurate measurements of flue gas temperature, O2, CO, CO2, both NO & NO2 for True NOx, SO2, H2S, and CxHy hydrocarbons throughout a cogeneration plant. The E8500 Plus includes a real-time software package with Bluetooth wireless communications to monitor, graph, and record all measurements and calculations.
