Overview: CEMS emissions auditing and trim control
For decades, boilerhouses, manufacturing plants and other industrial environments have used EGA’s (Exhaust Gas Analyser) to monitor flue emissions to comply with environmental regulations & to reduce fuel usage & emissions. The EGA EVO can operate as a standalone independent continuous monitor, or it can feed back its readings to an Autoflame MM Boiler Controller, allowing the MM to adjust the fuel/air ratio (trim) of the burner for optimised performance.
With built-in CEMS Auditing software, view reports by user-definable time periods (24 hours, 2 weeks, 1 month, 2 years, etc.) based on:
Mk8 EGA EPA Conformance
Meets all requirements set by US Environmental Protection Agency
Includes all the benefits of the Standard Mk8 EGA (CEMS Software, monitors up to 6 gases, touch screen) plus:
The US Environmental Protection Agency have certain requirements for monitoring boiler flue emissions. The Mk8 EGA EPA Conformance model has been specifically designed to conform to these requirements.
Enables automated cell calibrations on bottled calibration gas (4 bottles). Self-calibration process occurs once every 24 hours. During this process, the cells are each recalibrated using a zero value, and a span value. The following configuration options are available:
Additionally, the EPA EGA has the following information:
Heated Sample Line (HSL)
Heated Sample Line ensures sample gas is not diluted by water (condensate). The HSL maintains the exhaust gas temperature until the gases enter the E.G.A.
HSL temperature can be controlled to user-defined setting. The temperature is monitored to provide warning when not at the prescribed setting
The HSL operates by using a PI loop to maintain the set temperature
Mk8 EGA Evo Servicing and Calibration
The Autoflame EGA requires an annual service. During this service, the EGA is cleaned, recalibrated and inspected for faults.
EGA’s can be returned for these services to either our UK Manufacturing Headquarters, or to our partners in the USA, Midwest Combustion.

Mk8 O2 Interface
This module enables O2 trim with Mini Mk8 and Mk8 MM Controllers for limited budget applications. We generally recommend the Mk8 EGA Evo instead, as it enables a more advanced 3 parameter trim.
O2 interface setup
The default configuration for inputs and output 1 is 4-20mA, (0-10Vdc can also be used).
Inputs 2 and 3 are set to 150ºC and 20ºC as default, (4-20mA or 0-10Vdc can also be used).
Analogue Input 1 – O2 Signal Input
Analogue Input 2 – Stack Temperature Input
Analogue Input 3 – Inlet Temperature Input
Analogue Output 1 – Firing Rate Output
