ceramic tubes

The ceramic tube forms the inner lining of the blast tube in gas and oil burners, shielding the combustion head and surrounding metal components from the intense radiant heat generated at the flame root. Seated between the burner body and the combustion chamber opening, it maintains a stable thermal boundary that protects structural components and preserves correct flame geometry across a wide range of firing rates.

Selecting the correct ceramic tube depends on the outer and inner diameter, the overall length, and the profile of the seating face — whether flat, stepped or flanged. Wall thickness and ceramic grade also matter when the tube is subject to rapid thermal cycling or unusually high furnace temperatures. Cross-referencing an existing part by the Kromschroder order number or the original equipment designation is the most reliable route to an exact match.
