The resulting heat available for coal drying then suggested a fuel moisture reduction from 60% to 54% is possible. Reduction of the moisture content to 54% results in a reduction of fuel flow to the boiler and through the majority of the coal handling system.

The coal is conveyed from feed end to discharge end by vibrations and comes in contact with hot gas resulting in drying the coal. The combined action of vibrations and fluidization ensures uniform drying and product moisture.

Real Facts About Anthracite Coal In years past, deep mining was a very dangerous process used to extract coal from the earth to heat our homes and businesses. The US economy used it for over 180 years and it helped catapult our nation to the success it is today.

Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coal.

An innovative coal-drying technology that will extract more energy from high moisture coal at less cost and simultaneously reduce potentially harmful emissions is ready for commercial use after successful testing at a Minnesota electric utility.

Electric resistance heating is 100% energy efficient in the sense that all the incoming electric energy is converted to heat. However, most electricity is produced from coal, gas, or oil generators that convert only about 30% of the fuel's energy into electricity.

Moisture absorbs heat, so high moisture content in coal reduces the relative efficiency of heating when a coal is combusted. This is why low-rank, high-moisture coals have lower calorific values (Btu/lb) than high-rank, low-moisture coals.

What is the heat content of U.S. coal? In 2017, the annual average heat content of coal produced in the United States was about 19.78 million British thermal units (Btu) per short ton (2,000 pounds), and the annual average heat content of coal consumed was 19.46 million Btu per short ton.

Coal C initially self-heats similar to Coal A at 12.0% moisture, but only reaches a maximum temperature of 60 °C after approximately 30 h of testing before the coal temperature gradually decreases due to a combination of decreasing reactivity and evaporative heat loss.

High fuel moisture content adversely affects the material handling systems, such as coal pulverizers, the heat content of the fuel (HHV) and, consequently, boiler and unit efficiency. In addition, the fuel moisture evaporated during the combustion

Moisture in coal consists of inherent moisture (IM) and surface moisture (SM). The total moisture (TM) is a sum of IM and SM. IM is moisture which is an integral part of the coal seam in its natural state, including water in pores but excluding that in macroscopically visible fractures.

Buying coal is not as easy as picking up the first bag you see - there is a lot to consider: does it suit your type of stove/fire, how much heat is it going to produce, is it smokeless etc. but don't worry, our coal guide will help you to choose the right type.
