Gasification Introduced as the Most Sustainable Way to Burn Things

Gasification of wood is a simple technology that introduces secondary air to the falling ash which superheats it and combusts the ash and wood smoke to a point where there’s very little left.

The method is very efficient and gets the most energy out of a log of wood while leaving small ash to scrub out. Gasification is a technique for burning wood where the gases from the wood are burned at awfully elevated temperatures, and while it was employed at length fifty to a hundred years back, since the appearance of inexpensive oil in the latter 1950s and 1960s it’s been mostly ignored. Gasification works both at a simple level in wood stoves and in great gen stations feed MW of power into state electricity grids.

For a while the enormous generators like GE have recognised this and have been developing the highly technically classy Integrated Gasification Mixed Cycle ( IGCC ) Generator, since multi-millions of greenbacks into the concept. till quite recently society had forgotten the indisputable fact that gasification may also be sued at the domestic stove level and bring large efficieny and smoke emissions reduction benefits at the same time.

In a simple wood gasifier inventive design ( or a tiny electrical fan in numerous designs ) causes a downdraft which produces acute heat up to 2k degrees igniting all gases including smoke and creosote thus giving about a hundred percent potency. The gasification effect works by way of the downdraft that sucks wood gas from the firebox in the top chamber down into a bottom chamber where superheated combustion happens.
