I bought my furnace from Keystoker 11 years ago, and they told me to get oiled coal in order to,literally, cut down on water content in coal and cut down on rusting. It certainly makes sense as rust is a big deal with a stoker.
My coal supplier said they can oil the coal and then things got stressful. I got roughly 2 deliveries that appreared to be oiled due to a slight smell (nothing overpowering) of diesel fuel or motor oil, which was okay. Coal shined and slid well. Kept coal hopper, shovels and buckets used for coal glistening..rust-free.
The coal then came with an overpowering smell of something like kerosene. It and I was worried something flammable was on my coal. Well, sfter doing some research, I came to the conclusion that my delivery guy was buying it from the breaker un-oiled, pocketing the oil fee for himself and pouring a little kero one afterward. HE even said they called kero "coal oil' in the old days. haha
Soon I also discovered that my deliveries had been cut short for a very long time, which made me angry, so I dropped my delivery man for another guy.
Let's fast forward. My coal supplier, who also offered delivery services, claimed they had oiling capabilities but was sending me un-oiled coal. Hmmm. I watched this for a season before confronting one of the owners. He got testy and was basically speechless. Obviously, they were pocketing the extra money, assuming I didn't know the difference. But they had also been shorting my deliveries for the longest time. You see, I have lines inside my coal bin to tell me how much is there, and I gave them the benefit of the doubt for about 2 years, but 2 ton deliveries got too short to miss. And then I get rid of my longtime supplier.
Next I went on a search to find out what kind of oil they use and, after speaking to many coal haulers, including the owner of a now bankrupt coal company, was told to use a 5 or 10 grade/wt hydraulic fluid which I think is okay.
Adding water to the coal, I strongly feel, is a bad idea. I also do not think using vegetable oil is a good idea. This stuff is organic and can cause a variety of problems, including attracting rodents, in the longterm.
Moral: Don't trust the coal haulers or the breakers. Be watchful and, if possible, save money by oiling the coal yourself.
Any other good ideas would be appreciated.
