The Stratified Downdraft Gasifier 1. What is a wood gas generator and how does it work? The purpose of this report is to develop detailed, illustrated instructions for the fabrication, installation, and operation of a biomass gasifier unit i. These instructions have been prepared as a manual for use by any mechanic who is reasonably proficient in metal fabrication or engine repair.

Before , gas generator units were a familiar, but not extensively utilized, technology. However, petroleum shortages during World War II led to widespread gas generator applications in the transportation industries of Western Europe.
Charcoal-burning taxis, a related application, were still common in Korea as late as The United States, never faced with such prolonged or severe oil shortages, has lagged far behind Europe and the Orient in familiarity with and application of this technology; however, a catastrophe could so severely disrupt the supply of petroleum in this country that this technology might be critical in meeting the energy needs of some essential economic activities, such as the production and distribution of food.
The liquid fuels used in gasoline engines are vaporized before they enter the combustion chamber above the pistons. In diesel engines, the fuel is sprayed into the combustion chamber as fine droplets which burn as they vaporize. The purpose of a gasifier, then, is to transform solid fuels into gaseous ones and to keep the gas free of harmful constituents. A gas generator unit is, simultaneously, an energy converter and a filter. In these twin tasks lie its advantages and its difficulties.
The first question many people ask about gasifiers is, "Where does the combustible gas come from? Two-thirds is lost into the environment with the smoke. Gasification is a method of collecting the smoke and its combustible components.
Making a combustible gas from coal and wood began around in Europe. Such manufactured gas was used for street lights and was piped into houses for heating, lighting, and cooking. Factories used it for steam boilers, and farmers operated their machinery on wood gas and coal gas. After the discovery of large petroleum reserves in Pennsylvania in , the entire world changed to oil-a cheaper and more convenient fuel. Thousands of gas works all over the world were eventually dismantled.

The above mentioned designs can be adapted to a smaller setup. We have a subforum dedicated to small engines. Large generators will be more like automotive applications, with some added automation to keep things running smoothly. The ideal vehicle is a Dodge Dakota with a V8 engine. Wayne Keith has extensively developed gasifiers for this breed of trucks, and his gasifier design can easily keep pace with freeway traffic, even towing a small trailer for extra wood.
