We’re really excited to be stocking the Kelly Kettle Woodgas Stove! This is a long-awaited coming together of two great technologies: the trusty Kelly Kettle, and the super-clean burning woodgas stove.
Wild Stoves have been selling Woodgas Stoves since 2010. They are one of the most exciting products in our wide range, for their compact, clean burning and high-performance credentials. They literally boil the smoke out of wood then burn it. Cleanly, and hot.
The marriage of a Kelly Kettle with a Woodgas Stove means that you get more heat, less smoke, more versatility and outstanding overall performance.
The science of this marriage
For a wood-powered cooking set up:
Overall system efficiency = combustion efficiency X thermal transfer efficiency.
This means if you have great combustion efficiency (e.g. a woodgas stove) and great thermal transfer efficiency (a Kelly Kettle) you have great overall system efficiency. This is a great marriage.
The Kelly Kettle range in its basic form is excellent, but mainly thanks to its water-jacket design, which gives a large surface area for thermal transfer. The actual combustion is not great – it’s an effective but fairly rudimentary container for fire.
In fact the laws of good system design suggest you should separate combustion from thermal transfer for maximum efficiency. This achieves that: it allows combustion to complete within the woodgas stove, allowing thermal transfer to take proceed without cooling the combustion gases interfering with combustion.
