China needs to cut demand for coal by more than 80% by 2060, oil by around 60% and natural gas by more than 45% in order to realize its commitment of carbon neutrality by 2060, while renewables-based power generation, mainly wind and solar PV, needs to increase sevenfold between 2020 and 2060, the International Energy Agency, or IEA, said in its report …

Coal trader's web sites give base prices in the international market. We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.

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.

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.
