Can I use a small amount of coal if I just want a small fire?

The important factor is the whole grate area must be covered in order for the Anthracite Coal to burn properly. Also a deep bed of coal burns better than a shallow bed. This doesn’t mean the whole bed of coal will ignite, because coal burns from the bottom up. Therefore, it will only burn the bottom layers even if there is a deep bed of coal. Your coal will not burn if the whole grate area is not covered because the air flow will go around the coal instead of through the coal.

Does Anthracite Coal give off more heat in comparison to wood?

Yes, there is more heat produced by burning Anthracite Coal compared to burning wood. This is because there are more BTU’s in Anthracite Coal.

How do I make my stove burn warmer?

There are numerous ways to make the stove burn warmer. First, remove all the ash build up by shaking the ashes with the grate shaker. Next, allow for more air to enter through the air intakes. This can be done by adjusting the thermostat to a higher number, opening the ash door slides, opening the air intake knobs, or a combination of these methods. The last method is to apply more fuel, as you might not have enough fuel to maintain a hot fire.

How do I start Anthracite Coal?

Anthracite Coal starts differently compared to other fuel sources. There are three important factors that must occur to start Anthracite Coal successfully. The three factors are air flow, heat source, and fuel. First, there must be air flow and the air must come from the bottom and flow up through the coal. The next necessity is that there must be an already hot source of heat such as a kindling fire or hot charcoal. The last necessity is that there has to be enough Anthracite Coal to burn properly. This system of events occurs over a period of time and must be performed in stages. The first stage is to clear all of the ash to allow correct air flow. The next stage is to create a hot kindling or charcoal fire. And finally, the last stage is to cover the whole grate area one layer at a time with coal, allowing each layer to start burning before applying the next layer.

How many BTU’s are in Anthracite Coal?

There are around 13,500 BTU per pound of Anthracite Coal.
