Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

No it is not backwards.
By shortening the stroke turning the red nut in the pusher plate travels
more and it pushes more coal across the fire grate per cycle OR total stroke length-
Think of it this way:
A concrete pump pushes concrete within a set volume. This Volume is the pusher ram connected to the hydraulic cylinder(ram) that pushes the ready mix concrete to where it needs to go.
The faster the rams move the more concrete it pumps. The Keystoker KAA6 pusher plate does the same thing with shorter cycles moving a greater amount of coal per hour than the longer stroke AS the longer stroke makes fewer cycles per hour.
