View into burner-head

(Click to enlarge photo)

This is the view into the burner-head once the fuel has been stopped and the flames have died down. The flames do not just shoot out horizontally from the tube but rise vertically and curve over towards both sides of the tube and then exit nearer the top. The partly combusted wood can be seen at the bottom, there is no need for any mechanism to remove the ash as this naturally falls from the end of the tube under the action of the hot gases. Roughly 200 litres of wood-chips will last about 10 hours and will easily heat a medium sized house. All that is left afterwards is 1-2 litres of very fine ash for the garden.
