Producer Gas (Wood Gas) What is "ratio" ?
Producer Gas (Wood Gas) What is "ratio" ?
(OP)
Hello All, I have another post this forum, BUT...
In the world of "Petrol" eg: gas motor, the fuel to air ratio is what, 1 to 17 or something like that ?
I'm wondering, If anyone knows, what is the ratio for producer (wood) gas ? is it the same ?
Our sons fair project has had a spin off (our "new" outdoor water heater) and now I'm getting to the point in this "new project" of actually tring to get the most out of the wood we burn (gasification)
I've hunted the web, and to no avail, have I been able to find an answer....

Gasoline needs about 15.3 pounds of air per pound of combustible with zero excess air. The gross or high heating value of gasoline is around 19,400 BTU per pound. I don't have a heat of combustion for producer gas but it is a mixture of CO and N2. You will need to do some conversions but its a project isn't it. Good luck. Also actual air will be a few percent over theoretical or zero excess air.

aprox 6.27 lbs air per lb of fuel (on ratio O/R) and dry fuel.
About 30% of incoming O/R air is used to gasify.
Operating at 50% excess (XSA) air is good!
The smaller wood particle size you have the better you will gasify and 20% moisture content and less is preferred but I have gasified with MC at 37%. depends on physical makeup of furnace.
The perfect gasifying device is one that will float in the closest body of water. If it floats you know you have total control over the air and fuel inputs and that is exactly what it takes to make a great gasifier.
You will not be happy with attempts to gasify unless you have total and absolute control of all air going into the gasifier.
I have about 35 years experience with gasifiers and burning all types of solid fuels. If I can help further get in touch. That does not say I am an expert. Just that I have made a lot of mistakes and found their solution.
