Good Morning, ALL.
I’ve had problems reading this topic as I’m afraid it would just recreate a FEMA type in construction and performance.
I linked back to BobMac]s opening statements:
“The purpose of this topic is for members to put down here some of your K.I.S.S. ideas you have had; and have proved that it works by it (being) simple (to) build, and (proven) performance.”
“Not the place for theory but proven building facts that works.”
So, the title means, “Building a Gasifier: KISS”
For the longest time I was insisting from experiences that woven fiberglass stove rope would seal airtight. It just took using the larger diameter rope; with a made rope holding channel; and opposing raised compressing bead. Ha! Ha! Most ignore the opposing squeezing bead. Versus a flat surface squeeze. These will unevenly squeeze. And with use, wear, leak.
Another of mine after too many times multi-bolts flanges assembling, and disassembling, I have insisted that joints can be made flange-less. V-Band clamping. The barrel top method.
Or use external welded onto the housings U-legged lugs with a single pull tight bolt and nut. Three pairs. Four pairs if you just insist.
Flangeless. Right down to piping with the off-the-shelf; or scrap repurposed vehicle exhaust manifolds, to pipes, pieces. V-band clamped; or ball in socket types, three bolts drawn together.
And one KISS I saw Ben Peterson evolve into was learning to effectively build with zero cone shapes.
Joni and others do zero cones too.
WayneK does thin metals, no-math’s, overlapping slits forming for slopes.
My wood stoving experiences says line the center core-of-hell with loose fit sacrificial insulative purpose manufactured stove bricks.
Some have now done this on their gasifiers. My next from scratch builds will too. My current is too internally small to retrofit.
So KISS in constructing does not have to mean FEMA no-air-nozzles shit in performance.
Regardless of my personal opinions for serviceability; all-welded up can be performers too.
Aught to use Kritijans heavy plate building going all-welded up imho. That learned from lots of hard ran woodstoves too.
Thin metals all-weld-ups soon use evolve quickly into fix-and-patch, weekly. Or throw out, make another. Better be quick to make. You’d better have access to more, cheap/free, available makings.
