Why Rocket Combustion Works

Insulated combustion chamber

The L-shaped firebox concentrates heat at the point of combustion, driving temperatures high enough to achieve near-complete oxidation of wood gases — the primary source of smoke and CO.

Induced natural draft

The chimney effect created by the tall, insulated flue draws a strong, steady air supply through the fuel bed without any mechanical assistance — making startup reliable and combustion self-sustaining.

Small-diameter fuel feed

Only the tip of each piece of wood is burning at any time. This dramatically reduces the rate of fuel consumption versus top-lit or side-stoked fires, while maintaining consistent heat output.
