Understanding Your Wood-Fired Grill

Before we even think about tools or replacements, it’s crucial to understand the heart of your wood-fired grill: the burner.

Different Types of Burners

Wood-fired grills, while often simpler in design than their gas counterparts, can still utilize different burner types:

Traditional Pipe Burners: These are the most common, typically made of stainless steel or cast iron. They’re simple, durable, and distribute heat evenly.
Ribbon Burners: These feature a long, narrow ribbon of metal with tiny holes for the gas to escape. They provide a more consistent flame and heat distribution.
Infrared Burners: These burners use a ceramic or metal plate that is heated to a high temperature, emitting infrared radiation for intense searing.

The type of burner you have will influence the replacement process and the parts you’ll need.

Anatomy of a Burner System

A typical wood-fired grill burner system consists of:

Burner Tube: The main body of the burner, where the gas flows and combustion occurs.
Venturi Tube: This tube mixes air and gas before it enters the burner tube.
Orifice: A small opening that regulates the flow of gas into the venturi tube.
Igniter: A device that creates a spark to ignite the gas.
Control Valve: Controls the amount of gas flowing to the burner.

Why Burners Fail

Burners don’t last forever. Over time, they can fail due to:

Rust and Corrosion: Especially common in coastal areas or with grills that aren’t properly maintained.
Clogging: Food debris, grease, and insects can clog the burner ports, leading to uneven flames or no flame at all.
Cracking: Extreme heat and temperature fluctuations can cause burners to crack, leading to gas leaks.
Wear and Tear: Simply put, burners wear out with repeated use.
