The nature of fuel has a big impact on the design and operation of any fuel-fired kiln. Empirical rules established for solid fuel kilns are widely quoted as fundamental principles of kiln design, but are completely inappropriate for gas-fired or oil-fired kilns. This article explains some of the important differences and the implications for kiln design.

A gas burner works by mixing gas fuel with the right proportion of air for burning. The simplest and most commonly used gas burners for natural gas and LPG are atmospheric or venturi burners. They don’t need a blower or any moving parts. This article outlines their principles of operation and key parts, providing a basis for fault-finding diagnostics.

One reason to build a fuel-burning kiln is to produce beautiful reduction glaze effects. Whether kilns are wood-fired, gas-fired or oil-fired, the atmosphere can be starved of oxygen to produce these effects. This article outlines the chemical changes involved in combustion, explains the important differences between these types of fuel and the implications for the design and operation of the kiln.
