In Search of an Efficient Gas Burner

Keeping Your Gas Burners Clean and Efficient

During the breaks of one of our recent food manager certification MN training sessions, we were involved in a discussion on why a gas burner’s flame sometimes wavers or seems to be more yellow than the typical blue flame. We’ve come across this topic a few times, and this week we’d like to share how you can solve the problem of an inefficient gas burner.

Keeping Your Gas Burners Clean and Efficient
If you’re noticing that the burners that you use most frequently aren’t as efficient as they once were, the problem may be easily resolved with a thorough cleaning. Three sure signs that your burners may be in need of a little care include:

  • Uneven heat distribution
  • Flames at one or two burners aren’t as hot as they once were
  • Yellow flames mixed with blue

All three of these signs indicate that your gas distribution is being interrupted somewhere in the cap and head of your gas burner assembly. Your gas burner head is the round portion where the gas meets the flame from the pilot light and ignites. If you take a close look at this assembly, you will notice small, pin-point holes circling the head. These holes are where the flame comes from. If these holes become clogged, the gas cannot escape as quickly causing you to lose heat from that portion of your burner. This will cause weak yellow flames as spilled debris chars into carbon.

These assemblies are generally easy to remove and clean. If the holes are clogged, sometimes a simple toothpick can break free the debris that was interrupting the gas flow and producing a weak, yellow flame. Keeping your burners in top shape may take a little more effort than taking apart your burners and cleaning them out occasionally. Rather than break free the debris that is clogging your assembly, it is often a good idea to thoroughly clean the entire burner head. This will remove grease, spilled food product and dirt from your burner. If you have a situation where the gas flow is decreased or inconsistent to all of your burners or gas appliances, we strongly recommend that you consult a professional rather than attempt to fix the problem yourself. If you’re experiencing poor performance to your entire range, the issue may take more than a simple cleaning to resolve.
