I bought some anthracite

PostBy: archbolter On: Mon Jan 20, 2014 2:48 pm

I have a got hotblast coal furnace that I've been burning wood and bit coal in since September. I bought 3 bags of nut coal ( biggest size the had) to try out.

This stuff seems like a pain to light but it burns pretty. The only way i could get it to light is th start a small bit fire then add this to it.

I got about a 8 hour burn time to the one bag I loaded last night. Anybody got any tips? I get about the same if not a lil longer burn from my bit coal. But that's all I've ever burned so I'm a newbie. To this hard coal.

Any tips would be great. Thanks.

Welcome archbolter, I think your stove holds a lot more than 50 lbs, more like 100-120 to the top of the fire bricks. The experts on this type of furnace should be along soon enough though. There are some interesting retro- fits that can be done to increase efficiency and burn time with your stove. There are also some clones of your stove, one being a Clayton. Try using the search box in the upper right corner, there is also a lengthy thread about heating with a Clayton furnace on the Active post page 1 or 2. Best off luck. Lightning should be along soon...throw up the Bat signal!

Thanks very much Michael. My hotblast is a 1537m. One of the smaller ones, if that makes a difference.

Hi Partner, welcome aboard!! I have the Clayton 1537G which I think is pretty near identical to yours. What devices do you have installed? Barometric damper or manual pipe damper? Manometer? All natural draft or is there a combustion blower installed? Anthracite is quite a bit different than wood or bituminous coal and have different characteristics. Firstly, I would advise not to burn bituminous together with the anthracite, it will complicate your attempts. You can use a kindling wood fire or some cowboy charcoal to get your anthracite lit. After getting a good kindling wood fire going, add coal in 2 inch layers. Let each layer ignite before putting more on. Repeat this until you build it up to the top of the fire bricks. It may take 80 pounds to fill it initially.. Heat output is controlled by combustion air coming in under the grates, not by how much coal is in the fire box.

These furnaces are fickle to burn anthracite in. It took me a few specific modifications to make my coal burning steady and predictable. I only lit mine once this year, haven't lost the fire yet. I get 24 hour burns during mild winter weather of 25-35 degrees outside (heating 2500 sq ft) without it loosing any heat output with only slicing and poking under the grates in between. So don't get discouraged if things don't go well at first. Some learning curve is required as well as finding a tending technique that keeps her happy. :D

Thanks all the info. I have no draft fan but bells of natural draft. No nanometer. Have both a manual and barometric damper in line. I have so much draft on windy day that the BBC wasn't controlling it.
