Beetle-killed trees and woody residues degenerate and may lead to wildfires and uncontrolled CO2 emission. Woody biomass is known as a neutral CO2 solid fuel since it generates the same amount of CO2 that takes from atmosphere during its growing up. Cofiring woody biomass with coal in existing coal power plants is a reasonable solution to reduce the net amount of CO2 …

Net calorific value (NCV) assumes the water leaves with the combustion products without fully being condensed. Fuels should be compared based on the net calorific value. The calorific value of coal varies considerably depending on the ash, moisture content and the type of coal while calorific value of fuel oils are much more consistent.

Coal dust is an essential component of iron casting. To put it simply, iron casting involves melting the iron into a liquid state and pouring it into a mould. The mould is removed when the metal solidifies in the desired shape. Other metals employ coal dust in their manufacturing processes, but this page will focus on the iron casting application.
