Suppose you have a farm. They produce cereals and a quantity of straw. Do you want your energy on the website of the biomass, you have at your disposal. You may at your facility with fields of rape or rape and produce biodiesel. But you need for the first lye and methanol, since two of them can not be! And you can only biodiesel compression-ignition (diesel) engines. And what is, if you have an old GENSET powered by spark ignition (petrol / gasoline) engine? I think I have a solution for you …

They use a technology over 200 years. It is the biggest development has taken place during the Second World War, in the year 1940 in Europe. At that time, most fuel oil were obtained from military and there was no fuel on the road to civilians. Thus, it has its own fuel, gas, timber, wood or charcoal. In some countries, 95% of civilian transport (trucks, buses, boats of the fishermen) were supplied with gas.

What is wood, gas? From a chemical, it is a fuel mixture of carbon monoxide (CO), hydrogen (H2) and methane (CH4), with some diluted water vapor, carbon dioxide (CO2) and d nitrogen (N2). This gas can be easily to almost any internal combustion engine. Well … with the exception of those more modern, it would require that electronic sound changed.

What wood? If you heat wood, it is pyrolysed, ie all tar evaporate. While some oxygen, carbon bound inside cells of the wood burned to carbon dioxide. The fumes burn. If the gas burned by a layer of char very hot, they are reduced to carbon monoxide and hydrogen. A small amount of methane is also produced. When the gas is cooled and cleaned and particles of tar, it can be a combustion engine of a boiler or another device!

What you need your own wood, gas? You need a device, ie carburetor. It consists of fuel funnel, gasification of the boiler room and a number of filters. It is very easy to construct man during World War II, he made old water heater and stuff like that.

If the gas wood is it safe? Well, if you do not breathe, click OK. Carbon monoxide is toxic and very toxic, so that prudence is the use of wood gas. The engine of view, if clean, it is safe. The tar can condense inside the engine, for example, valves, which can lead to what the engine failure. The particles probably destroy surfaces contact pistons and cylinders. If the gas is hot, the engine will not work (hot gas, small and diluted energy per unit volume), but it will not interfere.

All the disadvantages? One is mentioned. Souffrent petrol engines is 1 / 3 of a power outage - the gas has small wood heat. Diesel engines are not suffering as a power outage because they work in mixtures geschichteten and, therefore, we can introduce more wood gas, loss of performance. You must leave some small quantities of diesel fuel injection for the cylinders of flammable gases in the wood.

Interested? A liter of gasoline can be replaced by 2.5 - 4 kg (5.5 - 9 pounds) of wood. Is not this fantastic!
