Nature’s Comfort Outdoor Coal Furnaces

Burning Coal

Many manufacturers changed to natural gas in making their products
but are now switching back to coal because it is less expensive.

Coal burns super hot and needs high quality mild steel – like ours;
one of the few that can withstand the intense heat.

The Nature’s Comfort Outdoor Coal Furnace is specifically designed to
burn coal and it comes with a coal shaker grate to help get rid of clinkers.

We carry 6 sizes of COAL boilers.
These models are specifically designed to burn coal
Each shaker grate is 3/4″ cast iron

With the fan feeding oxygen in from the bottom,
the coal burns easily. Shaker grates are installed in
all models to help get rid of the clinkers.

Grades of Coal

Anthracite – this type of coal has the highest percentage of fixed carbon and a lower percentage of volatile material than all other coals, making it harder to ignite. However, when it is ignited, it burns relatively smokeless.The most well-known anthracite mines in the United States are in western Pennsylvania.

Bituminous – Bituminous coal is the most abundant and most widely used coal. This is the type of coal found in the Appalachian region. It has a higher heating potential and is used for making coke. It has a higher percentage of fixed carbon, greater heat value and better weathering characteristics than lignite and sub-lignite coals.Most of the non-metallurgical grades of bituminous coal are burned in boilers or furnaces to obtain thermal energy for generating electricity. Because bituminous coal is softer than anthracite, it is often referred to as soft coal.  It does emit smoke as it burns, unlike anthracite.

However, there is a region in Southern West Virginia where the bituminous coal burns relatively smokeless. The Smokeless Coal Fields of Southern West Virginia are unique in the world.

Sub-bituminous – A lesser grade of coal, it has more moisture and less carbon than bituminous.  Nut Coal – Very small coal – about 1/4″ in size. See important note below.  Click on pictures below for a bigger image.  >>>

You must notify us, if you plan on using “NUT COAL”, rice coal or pea coal, as they are all very small.

You cannot burn “run of the mine” coal, without voiding the warranty
because it burns way too hot.

In the United States, the coal power plants
generate 50% of the electricity produced.
