I was .035 when I set everything this morning and now down to .02 but is not getting any moisture in the hopper so I may leave so I have a hotter fire? If I just run 1 burner wide open it does not have enough heat to maintain.

At this point I would slow the feed rate on the two stokers and open the
air shutters on the combustion blowers where they recommend per
the picture in the LL manual as you appear to have too little air entering
the two stokers fire beds and too much coal feeding from what I can see of the image.
I would also try putting aluminum foil over the barometric damper as well.
What you need to tell us and the folks at LL is what the fire looks like-
1. how much raw coal is on the stoker bed-length of unburned coal on stoker bed before fire
a. how thick/deep the coal bed is as it is burning
2. how big the fire is in TOTAL length
a. how tall the fire is-it should be near the top of the firebox
3. how much ash there is on the stoker bed-length of ash bed on stoker
OK NOW
Raw coal length + burning coals length + ash bed length - you need to explain to Matt what the stoker bed looks like when its burning.
4. is there a regulating gate/coal flow control gate for both stokers to control
the feed rate of the coal entering the stoker fire beds?
If there is a pair of gates too regulate the flow of coal you may just need to lower
them and then open the air shutters to the recommended width to allow more combustion
air to enter the stoker beds.
Don't give up on the rice coal yet as your stoker needs to be adjusted.
