How do you seal off the air from comming arourd the stoker unit and mano tube.that's some of your problem,but not the worst.
I believe the stoker unit is too high in the boiler,the flames need to sweep the sides in order to absorb the heat into the water.Is there anyway to lower the unit in the door.
Yeah that is a problem I still have to solve, but this is still experimental. Fire is not going towards the hopper. I do not like to change the fire door since I like to keep this multi-fuel when wood is around.
can you slide the damper plate closed more.When the stoker unit is runnig it's pushing all the heat to the top and out thru the chimney before the heat can be absorbed.
The damper plate does not close the chimney but only forces the heat through a 5" channel and then out the stack see picture 2. Not the blocks I set there to reduce the air speed but are no removed.
I love that underfeed idea. what brand is that, where is it, how much is it , how many are there around,
i have a gentlemens stoker that I wanted to use/ experiment but it feeds the coal from the other side This one seems to feed coal from the front.
What size is the required opening for the ash tray?
Dennis I noticed that did not quote your name in the comments quotes, try to figure "how to" later, my excuses.
