Just for the record, I have had many problems with wet coal. I use an Alaska 140 auger feed which seems to bind up when the coal gets too wet and the fire goes out. It seems as though the coal dust becomes a thick slurry which can bind up the auger. I also get a lot of sulfurous odor when I run with the bin door open and a lot of condensation and corrosion when I run with the bin door closed. Seems like there is no good way to solve this problem except to change coal suppliers. Even though I poke holes in the lowest point of the bags and let them drain for at least 24 hours there is still too much moisture in the bags. I never have this problem when I use coal packaged in woven bags. I also ran bulk pea coal in another stove for 10 years without any odor or corrosion issues .

I am still struggling with damp/wet coal in my boiler. I think the problem is my boiler is in the cold garage so the coal never dries out, it does not drop into the feeder/pusher properly when wet, so I have to run it at max stroke. Sometimes that works and sometimes it doesn't. I will sun dry my 5 ton/winters worth of coal during the summer months and store it in a waterproof shed.

Does anyone have experience with the Field Control Chimney draft inducer with the EFM DF-520?

Will it block natural draft when the stoker is NOT running?

Thanks,

Dave

Just got coal delivery today, and they switched suppliers. Is Gauley Coal any good?
