Everything I need to know about Wood Gas

Wood Gas


Most of you will agree that with enormous growth in the automobile industry, the price for oil and petrol has increased to an extensive rate. There is a price hike in oil as with each passing day, it is falling short. With the introductions of eco friendly substitutes most of you might have heard about the alternative fuel source. Since our mother earth is covered with green plants and trees, it supports us to convert sunlight into fuel and biomass products. Since hydrogen gas cannot be utilized for practical energy, wood gas is introduced which has high concentration of hydrogen and offers a great burning. Hydrogen gas is made from wood and coal and also can be taken as an alternative name for “producer’s gas”.

Hydrogen gas is generally considered as good for fuels since it burns very fast and also it is not a friendly gas as it is very hard to shift and store. So when making wood gas, half of the fuel contains practical fuel value and the rest from biomass and wood. Wood Gas is usually made from wood, power, synthesis of fuel and ammonia, biomass and heat waste. The gasification of wood gas happens when, air and fuel combined together they meet, flaming pyrolsis which in return produces charcoal and gas. This is again consumed to produce more gas. The gas is usually sucked out along with charcoal ash particles.

Volvo 240 wood gas powered car be the main example for any such assumption. To make Volvo 240 run on wood-gas was not a very easy job, and it has taken 1000 hours man hour and also almost a year to introduce the system that uses wood gas to provide power to the engine. The entire process involved cleaning of cyclone bin, dumping of charcoal dust into the compost, sixty pounds of wood that is filled in the fuel bin, sparking up the gasifiers with the help of diesel glow plug and flaring of any of the carbon monoxide and hydrogen surplus. The estimated cost to this entire process is almost fifteen to twenty thousand Euros.

The benefits

In this generation very few people are using wood gas as most of you are very much aware of the benefits of using this fuel.
