A gasifyer is used to heat wood or other organic matter to a temperature great enough to liberate the volatile elements inside. These gasses when liberated can be burned for heating, or used in an internal combustion engine to make energy. The fundamental structure of the gasifier may be a container perhaps the size of an oil drum which needs to be well insulated to retain the heat.
A small layer of burning fuel is held within a container inside the drum. Outside air is allowed through to the bed of fuel creating a controlled burn, and starting the creation of gas.
Being self contained has a number of advantages.
This small-scale controlled fire is exactly what is needed to allow the gasses to be released uniformly. The heat produced is also used to dry and heat the wood chips, so that as they fall into the grating they are in the ideal condition to replace the burnt-out mass. Temperatures of the order of 1200 degrees F should be aimed for. The red-hot unburned gasses are allowed to escape from the top of the container. They then need to be cooled and filtered, in part to scrub the gas, especially if it is to be burned in an engine, and cooled to produce a denser mixture which is more thermally efficient.
A particular advantage is a gasifyer is it is self contained yet small enough to be transportable by pallet or trailer. The approximate size of an oil drum can be made to run a four cylinder engine, but if you are burning something which is essentially a waste product, wood chips or saw dust, the gas made from that is just as good quality as the gas from an expensive fuel.
Any combination of chipped wood and or branches, rice or maize husks, shells, pits, animal droppings, in truth any waste natural material, may be used. Even rapid growing willow might be planted as a fuel harvest.
Could this be a fresh source of fuel? Commercial farming needs to expend money disposing of large amounts of waste to landfill. And not to forget the char produced by the gasifier is a good soil conditioner and fertiliser, a environmentally-friendly bonus?
Using a gasifier will seriously cut house hold expanses, even provide off grid living.
The gasses, regularly called syngas or producer gas, can be especially clean burning with little or no pollution.
Many claim that 1 gallon of petrol is equivalent to 20lbs of dry chipped wood. A gasifier of suitable size will furnish all the gas to run a selected engine, the bigger the gasifier the bigger the engine. A gasifyer does not necessarily call for any external power although this will help to start the machine, someone will however have to fuel the machine. With an internal combustion engine the induction will draw air through the hearth creating a self sustaining cycle.
As a green alternative energy source a gasifyer and petrol generator offers a solid solution.
