WET Coal vs. DRY Coal

WET Coal vs. DRY Coal

PostBy: RMA On: Fri Mar 20, 2009 6:46 pm

If we are buying Rice coal vs. (say) Nut coal at the same $'s per ton, when they're wet; aren't we paying more for the Rice than the Nut? The rice would retain significantly more water, wouldn't it?

Then the water would steam in the combustion chamber cooling its temperature a bit, wouldn't it?
Seems like we pay twice for the water+coal.

It seems that dry dusty coal, would be the better value, save the cleanliness aspect!

I think you are right. I found a local dealer that delivered me DRY Blaschak Rice. Yes, I checked it continuously as my 3 ton poured down the truck chute, and I only found a couple clumps, that easily broke up with a 'Wack' from the shovel. No moisture to speak of. I was happy to see this, as I was worried about paying for the weight of alot of snow and ice. This was in Late January, right after a storm passed the east coast.
I tried Bagged Blaschat previously, and wow, what a mess! Each bag had up to one gallon of water in it! :shock:

Well bob the old timers claim wet coal is better. If there is any truth to that I really don't know.

The rice will certainly retain more water. If you're getting bulk delivery you can request dry coal and most dealers should be able to fulfill that wish however a) unless its stored inside or they scrape the sides of the stock pile rice will never fully be dry and b) if you are getting this delivered into your house you will most likely order it only once. I've had customers request this and they have only ever did it once. ;)

The water content in one ton of coal that has been freshly loaded from the setup at Hudson where it's fully washed before going into the truck probably amounts to about 50lbs. with nut and maybe 75lbs. with the rice over a single ton. This would be after the truck is loaded and most of the water is drained off. The fines and smaller pieces removed during this final cleaning especially from the nut coal more than makes up for the water (e.g you're getting rid of dirt and dust and replacing it with water).

Yep, unless you are prepared for the dust, get it wetted down. I use a galvanized Chicken-feed scoop to load my hopper. I have to make sure I don't 'pour' the rice into the hopper, as it would make a very-visible dust cloud that would hover over the hopper. I have to lower the feed-scoop into the hopper, then tip it so the rice slides off the scoop without dropping, into the bottom of the hopper. Its the same method I use for emtying ashes from the fireplace, without making a cloud of ash in front of the fireplace.
I like dry rice. It doesn't stick to the sides of the hopper. :D

I was referring to the actual delivery, most of my customers had their coal bin in the house. ;)

Wow.... I cannot imagine the dust created from an in-house delivery of dry coal!

I got my 2nd load of coal yesterday (wet Reading 4 ton), my bin was filled but my extra 275 gallon tote only came to about a third filled.

I took a small #1 wet sample in a clean empty luncheon meat container and measured it out on a postage scale. When dried out, +-15oz. 4 tons weighs in at #8000, losing 1 oz per lb you end up missing +- #500, which is quite substantial!

However in looking at the bill, no tax or delivery charge...also from what I am told, Reading coal is much more efficient, burns hotter and longer. Old ashes showed charcoal, and bits of un-burned coal, lets see what end results will be with no mechanical adjustments once I get into the Reading.

With the weather being as it is in the North East right now 44degrees, December 23, 4:30 AM! It may be next year before I do get into the new stuff...Merry Christmas to all!

Oh and as far as dusty coal, see photo!

You do not hear much about Reading coal in the forum. Is it not a common coal to the markets? Being a 1st year coal burner after burning 10 cords of wood /year for 40 years, I purchased 4 tons of bagged Reading coal for my 1st year. Have burned about 2800 lbs. since the beginning of October, and some bags have considerable water & some are just damp coal period. Are all the bagged coals about the same with the moisture content issue? If so, I am thinking of trying to buy bulk, say 5+ tons next summer if it is available in my area. Does that get washed before delivery also?

The breaker uses a heavy media process to sort the rock from the coal. This process makes the coal wet.
When you pick coal up in bulk from the breaker they give a water allowance, in other words they charge for less than the actual net. Bagged coal is supposedly dried before bagging to get the true weight. The bags get wet afterwards from sitting out in the elements.

Bagged coal in poly bags cannot gain moisture they are almost hermetically sealed. Woven bags might gain moisture sitting out in the elements.
Dry coal can be nasty if moved quickly, I spray mine with peanut oil so when it is brought inside it stays pretty much dustless. I will admit the added oil makes the outdoor hopper a little crusty over time, but all my inside pails, stove hopper, stay nice.
