A gasifyer is used to heat wood or other organic matter to a temperature great enough to release the volatile elements inside. Once liberated the gasses can either be used for heat or combusted in an engine to create energy. The simplest element of the gasifier is that is a canister that is insulated to hold in the heat.
A modest bed 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 production of gas.
Being self contained has a lot of advantages.
This small controlled fire is precisely what is needed to allow the gasses to be liberated evenly. The heat produced is also used to dry out and heat up the wood chips, so that as they go down into the grating they are in the ideal condition to replace the burnt mass. Ideally the fire should make about 1200 degrees F. These hot volatile gasses ascend naturally and escape at the top of the cylinder. The gasses are then cooled and filtered, the cleanup is to cause less damage in an engine, and a denser gas has more energy.
Some of the main advantages of the gasifyer is it may be made small enough to be self contained and transportable, on a trailer or trolley. An oil drum sized producer should be able to drive a modest four cylinder engine, and the gas from a poor fuel is as good as that from an costly one.
Waste products such as chipped branches and wood, rice, corn coconut remains, in any combination, even chicken litter. For example fast growing willow may be used in areas with dependable water but little commercial waste.
The amount of money spent by commercial agriculture disposing of it’s waste, and landfill use, might be saved by using this as a fuel. And not to overlook the char produced by the gasifier is a good soil conditioner and fertiliser, a green bonus?
A large industrial gasifier might have to be used in an district heating undertaking or in a large farm yard waste energy producer in order to obtain economies of scale.
But, I am more concerned with smaller gasifyers to subsidise house hold costs, or off grid living.
The gasses, regularly called syngas or producer gas, can be extremely clean burning with little or no contamination.
Many claim that 1 gallon of gasolene is equal to 20lbs of dry chipped wood. A gasifier of reasonable size will supply all the gas to run a certain engine, the bigger the gasifier the bigger the engine. A gasifyer does not necessarily need 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 inductance will draw air through the hearth creating a self sustaining sequence.Check Out The Gasifyer.com
A gasifyer with a gasoline or diesel engine generator and a prepared supply of fuel, makes this an ideal alternative energy source.
