A gasifyer is used to heat wood or other organic matter to a temperature high enough to release the volatile elements inside. The gasses produced can be burnt in an engine to make power or simply burned in a heating system. The simplest element of the gasifier is that is a container that is insulated to keep in the heat.
The container has within it a layer of burning fuel. This has access to outside air, allowing a small portion to burn, but under controlled conditions, and begin the gas production.
Being self contained has lots of advantages.
This small-scale controlled fire is just what is needed to allow the gasses to be released evenly. This heat is used to dry and heat up the fuel stock, so that when it falls into the fire grate, it will readily burn. Ideally the fire should make about 1200 degrees F. The top of the cylinder has a pipe that allows the combustion gasses to escape. They are then cooled, to make the gas denser, and filtered particulary if they are to be burnt in an engine.
The gasifier then is like a small power station, self contained, but still transportable if necessary. A four cylinder engine needs an oil drum sized gas producer, but if the fuel is a waste product, the gas is just as good.
The types of fuel normally used will be waste wood chips, chipped branches, coconut waste, rice and corn husks and even battery chicken shed litter. In particular parts a fuel crop such as a fast growing willow may be used.
The amount of cash spent by commercial agriculture disposing of it’s waste, and landfill usage, could be saved by using this as a fuel. The gasifyer residue, or char, is an excellent soil conditioner, making it a very environmentally-friendly alternative.
My concern is more with the usage of a gasifyer to tighten house hold expenses and or off grid living.
household gasification has the added benefit of producing gasses, regularly called syngas, that are very clean burning, producing little or no contamination.
1 gallon of gasolene is said by many to be equivalent to 20lbs of dry chipped wood. A reasonably sized gasifier can be made to provide all the gas for a selected engine, the bigger the gasifier the bigger the engine. Gasifyers can be designed to require no external power, though having a forced draught helps the device to start, and of course some one or some thing has to feed the fuel into the hopper. Once working the induction from an internal combustion engine will pull air through the hearth, neatly making it self sustaining.Check Out The Gasifyer.com
As a eco-friendly alternate energy source a gasifyer and gasoline generator offers a genuine solution.
