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 a very thick firebox – like ours- to withstand the intense heat.
The Shaver Coal Burning Furnace is specifically designed to burn coal and comes with a shaker grate to help get rid of clinkers.
However, COAL AND WOOD can be burned separately or simultaneously.
Our shaker grate is the FIRST adjustable shaker grate in the industry! You can adjust the spacing from ½” to 1″ to accommodate different types of coal.
We carry 4 sizes of COAL boilers. These models are specifically designed to burn coal but you can burn wood too. With the fan feeding oxygen in from the bottom, the coal burns easily. Shaker grates are installed in all models:
We now carry FIVE different sizes of outdoor wood burning furnaces:
|MODEL||RETAIL PRICE||HEATS||WATER CAPACITY||BTU RATING|
|Shaver Coal Series 165||$5,577||4,000 sq. ft.||170 gallons||175,000|
|Shaver Coal Series 250||$6,527||5,500 sq. ft.||230 gallons||254,000|
|Shaver Coal Series 290||$6,877||7,000 sq. ft.||260 gallons||330,000|
|Shaver Coal Series 340||$7,577||8,000 sq. ft.||300 gallons||346,000|
You must notify us, if you plan on using “NUT COAL”. This requires a different grate and a bigger fan – at a slightly higher cost.
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 the United States, the coal power plants generate 50% of the electricity produced.
