What type of coal burns the most effeciently?
Anthracite coal burns the most efficiently because it has the highest carbon content and the lowest moisture content among all types of coal. It produces more heat and less smoke compared to other types of coal.
Which type of coal contains 90 percent carbon and is smoke less?
Anthracite coal contains approximately 90 percent carbon and is known for being a clean-burning fuel with less smoke. It is the highest rank of coal and is often used in heating and residential applications due to its high carbon content and low emissions.
What is a soft brown coal with less moisture called?
A soft brown coal with less moisture is called bituminous coal.
Which type of coal burns the cleanest?
Anthracite coal burns the cleanest among the different types of coal. It produces less smoke and emissions compared to other types like bituminous or lignite coal, making it a more environmentally friendly option for heating purposes.

London-type smog forms when particles in coal smoke combine with water droplets in humid air.
What the calorific value of coal?
The calorific value of coal varies depending on the type of coal, but on average it is around 24-35 million joules per kilogram (MJ/kg). This means that coal can release a significant amount of heat energy when burned, making it a valuable source of energy for power generation and heating.
