Burns what you’ve already got

If it grows, we can probably burn it. Wet or dry, clean or dirty. One load of chips like this runs a greenhouse for weeks.

The chain grate that doesn’t jam

Fuel spreads evenly across a moving grate of solid 6″ x 1″ x 2″ high-temp steel bars. The whole bed burns, not just a hot spot. As the grate turns over the end, ash drops off and leaves the system on its own. Wet chips, dirty bark, straw, husks: it keeps turning.

WET & DIRTY FUEL Burns without jamming	AUTO ASH REMOVAL No shovelling

Inside the firebox

Full bed burning, not a hot spot

Throw it in.

If it fits through the door, it comes out the other end. Pick something from the loader bucket and watch it go through the chain grate stoker.

Cutaway of an SCW chain grate stoker: fuel enters through a slot in the end wall, burns in the first foot of the grate, and the ash rides off the open end into the ash hopper.

Fuel comes in through a slot in the end wall. The fire stays in the first foot of the grate; after that the embers burn out and grey ash rides to the open end and drops into the ash hopper. Rocks, nails and bark ride off the same way.

Real grate timing (10 s push, 40 s rest)

The metering screws feed fuel in all the time. The grate indexes: it pushes for a few seconds, then rests, and ash drops off the end only while it pushes. Shown here condensed; tick the box for the real timing.
