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 Hyprotherm Outdoor Coal Furnace is specifically designed to
burn coal and it comes with a coal shaker grate to help get rid of 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 eastern Pennsylvania.
We offer Anthracite Coal (1.75″ to 3″)
that is stove-egg size for sale.
There are 50 bags per pallet,
and each bag weighs 40 lbs.
This coal is cleaned coal
and does not need to be removed from the bag
before being put in the coal boiler.
Each bag costs $8.00,
so each pallet costs $400.00.
Each pallet weighs 2,100 lbs
and the pallets are 40″ x 48″ x 48″
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.

middle picture – rice coal
right picture – pea coal
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.
