A quick jaunt up north to Enfield on the train from Hackney Downs and we are in Gunpowder Park at The Energy Cafe for a workshop on pedal power. Andrew was also about and demonstrating his smoke-free wood stove which impressed me muchly.
Hooking up a fan to feed the flames more air increases the efficiency of the combustion and decreases the amount of smoke, which is essentially unburnt hydrocarbons or very small bits of wood to you and me.
All of the stove had been made from reused parts found in local skips. The main body was an old flue buried into a tyre filled with soil, the fan was from an old laptop. As the flue was already double walled it provided excellent insulation so the wood could burn at a higher temperature. The fan created a vortex in the main chamber which meant better mixing of air again leading to a higher burn temperature resulting in no smoke at all and 5kW of heat apparently!
