Homemade Gasifier Uses Wood Pellets To Run Generator

Categories: Energy

This Gasifier uses wood pellets to create flammable mixture that a generator can run on without gasoline. This video shows how it was constructed, how it works, and how to use it from start to finish. Great project for anyone looking for alternative energy or wanting to live off the grid.

Gasifier history can be dated back far earlier than usually stated. In 1609, the Belgian chemist Jan Baptista Van Helmon found that gas was produced from heating wood and coal. Sixty years later in 1669 Thomas Shirley conducted experiments with carburetted hydrogen and thirty years on John Clayton obtained coal gas from pyrolitic experiments.

Wikipedia says "Gasification is a process that converts organic or fossil fuel based carbonaceous materials into carbon monoxide, hydrogen andcarbon dioxide. This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas (from synthesis gas or synthetic gas) or producer gas and is itself a fuel. The power derived from gasification and combustion of the resultant gas is considered to be a source of renewable energy if the gasified compounds were obtained from biomass.

The advantage of gasification is that using the syngas is potentially more efficient than direct combustion of the original fuel because it can be combusted at higher temperatures or even in fuel cells, so that the thermodynamic upper limit to the efficiency defined byCarnot's rule is higher or (in case of fuel cells) not applicable. 

Syngas may be burned directly in gas engines, used to produce methanoland hydrogen, or converted via the Fischer–Tropsch process into synthetic fuel. Gasification can also begin with material which would otherwise have been disposed of such as biodegradable waste. In addition, the high-temperature process refines out corrosive ash elements such as chloride and potassium, allowing clean gas production from otherwise problematic fuels. Gasification of fossil fuels is currently widely used on industrial scales to generate electricity."
