Re-reading my last post I come off sounding like either a know-it-all; or a done-it-all.
On my own personal efforts I wasted at least two years with all of my decades of wood stoving experiences believing that using hundreds of pounds of core system thermal mass would be a jump-ahead inspiration. After all I was dedicated stationary-use so I could afford the space and weight to do this.
Well, yeah. High amounts of process carrying forward thermal mass would have been fine on a 24/7 need gas producer! Like the old town gasplant systems. The IISc 1990’s to current evolved systems!
Personal use for small generating engines it was an input fuel-use hog!
I actually needed quick to heat-up to good gas making in a true 2-4 hours a day stints; twice a day done, to match our home energy use needs.
Overlapping with this was my two years efforts wasted (again from my woodstoving experiences) insisting that I could-too make 18" long split/cut stick form fuelwood imputs work. Ha! Skip right on past all of that labors intensive wood chunking.
Well, yeah. Stick-form can be made to work kinnda’sorta. Turns a fellow into a system babysitter keeping those burn-heat devolving sticks to char-chunks release, with minimum fines, and settle into a non-bypassing upper system gasses converting glowing char bed! A few hard limb knots in the stick-splits and you are screwed with irregular formed bed included bypassing lumps! Or, bed flow choked from the breaker-barred off char-fines!
So actually rather amazing that the different waves of actual needs-must gasifier system users in the late 1800’s into the pre-WWI early1900’s; then the later vehicle guys 1930’s into early 1950’s with their made mobile books, summary’s, had the Middle-Way to get’r-gone already mapped out.
I am not alone in wasted times efforts. Some (like I was) thinking their in-depth real-life experiences will lead to a zoom-zoom up in performances. Like process plant levels of electronic control systems experiences. Like actual Nuclear-plant capable certified welders. Like degree’ed, actual Engineers. Like too many I-WannaBee-Believers of many different stripes.
Inline with some of the advice’s given to this topics originator:
Pick a different engine applied-power combo, that will be more able to use what fuel-gasses you can make, for the working purposed you want to put it to work for.
Different way to view this make-woodgas-the-same-capabilty-as-gasoline is to realized WHICH gasoline? Gasoline has evolved too over the last 150 years. Been re-formulated for specific needs and purposes. So . . . comparable to . . .
Current day 10% ethanol clean-air made to work with high pressures EFI gasoline?
Post WWII very high 9toxic) lead doped high compression-able gasoline?
Before the late 1920’s no-lead “natural-distilled out” non-reformulated but wildly variable, from pump-distributor to pump-distributor gasoline?
Bush-made, from crude stolen out of the pipeline, “Nigerian” bootleg gasoline?
IC piston engines: and engine gasoline fuel mixture system can be made for any of these widely variable gasoline’s. But not for all of them with the same setups. And certainly not live long life’s ran outside to their spec ranges of gasoline’s fuel purpose designs.
Go try running a can of white-gasoline stove fuel in any modern gasoline engine. Engine working. Loaded down. Pre-ignitions misfiring and pinging. Backfiring. Overheating.
Early EFI systems in the 1960’s required large capacity, expensive, micro-fine gasoline fuel filters to not waxes clog up the fuel injectors. What changed? The delivered spec’s for pump available gasoline!
Ha! Woodgas can run all of the decades gasoline/gaseous fueled engine combinations. So what’s a little power loss. You have power loss with spec grade propane and methane too. Too much equipment usability set back losses with these fuels and you just need to up-size the engine to make the power that you do need to get the work done that you need done.
