[Gasification] coal gasification help

[Aaron V. Passow]

I have been playing with wood gas but have found it inadequate for my needs as the bulk of fuel necessary to run a vehicle is inconvenient and the cost of coal is quite reasonable in our area so I'm looking for any one who has info on a coal gassifier design foe mobile use especially grate designs and how to avoid clogging and how to handle clinkers your assistance is greatly appreciated
