GAS-L: Wood Gasification fuel Canisters

[Ken Boak <kenboak@stirlingservice.freeserve.co.uk>]

Listers,

Fuel handling for a modern wood gas car is going to be the major issue for public acceptability. Ideally the fuel should require little or no human handling and the ash and clinker should be disposed of in a user friendly manner. Here is one idea which could help to implement such a sheme. 

Imagine a 5 gallon drum made from cardboard , with steel endcaps, full of compressed sawdust. Down the centre of the drum is a cylindrical hole full of charcoal pieces.

This could be a standard cartridge of fuel to be loaded into an automotive gasifier. The 5 gallon drum would hold enough compressed fuel to propel a vehicle from 60 to 100 miles, and remain of a size, shape and weight that is not too cumbersome for the average adult to handle.

On loading, the centre of each endcap is pierced, the charcoal is ignited, and begins to burn from the centre outwards, producing heat which pyrolises (gasifies) the compressed sawdust. Sufficient air, and exhaust gases are introduced at the bottom of the can with the generated gas being collected at the top.

When the full charge is consumed, the outer cardboard wall of the drum is burnt away, allowing the upper endcap to fall over the lower cap, forming a closed "tin" container with the ashes inside. At this point a new fuel canister could be added on top, and the process repeated until several canisters have been exhausted. 

This method would allow fuel to be handled in a compact, clean form and also allow the use of sawdust (otherwise wasted) to be used as a convenient fuel.
