Free Webinar: Intro to Air-Fuel Ratio Control

Periodic checking and resetting of air-fuel ratios for burners is one of the easiest ways to get maximum efficiency out of fuel-fired process heating equipment like furnaces, ovens, heaters, and boilers. The efficiency of your process heating system can be reduced considerably if the combustion air supply is significantly higher or lower than the theoretically required air.

In our December webinar, Lesman's own A.J. Piskor will discuss control methods to help reduce energy costs and help you adhere to environmental regulations regarding stack emissions.

This 45-minute webinar will cover these topics and more:

  • A brief review of the chemistry of combustion
  • The importance of air-fuel ratio control
  • Methods for ratio control (mechanical linkage, ratio regulators, electronic linkage, and mass flow control) and the pros and cons of each
  • Sample air-fuel ratio control calculations
  • Your questions answered: Live Q&A

Tuesday, December 9, 9:00am Central (10:00am Eastern)

Please join us for the webinar. Or, if you're already booked then, register anyway and we'll let you know when the recording is posted to our website.
