Harmon mag stocker not running right

Coal is dry or acceptable, bad issue with damp coal, after picking up 1/2 ton last Saturday. Problem is I can't get the heat out of the stocker. I put combustion blower directly in outlet, this seems to giving it a great burn, however hot coal is being pushed of grates. It set for 1dot and Mano reading looks fine. Any ideas, only change was coal?

All I can tell you is with my Harman,the damp or worse,wet coal was a huge no-no. After learning the hard way,I loaded my bulk rice in breathable feed bags that allowed for moisture to "breath out" after placing 5-10 bags in proximity to the heat of the stove. They'd dry out nicely,and when it was load time,I'd put the untied open end of the bag down in the hopper and lift to unload. Very low dust loading of the dry rice was achieved,and happy-complete burning occurred. Give it a shot. My situation was easy due to the stove being in the basement and having the feed bags of rice 5' away didn't impact anything. if your stove is in a living area,try the feed bag routine as ambient warm air would still allow moisture to go through the coal to the bottom of the bag and help you out. On your next bulk load,do what you can to keep the coal pile dry and cozy and that Stoker ought to behave a lot better for you.....

Make sure the air holes in the grates a clear. Also, does your coal have a lot of fines?
