What is smokeless coal?
A smokeless coal is a coal which does not produce visible smoke when burned and emits lower levels of carbon dioxide into the atmosphere.
Anthracite coal is a naturally smokeless fuel and Coalite or Phurnacite are examples of manufactured smokeless fuels. Although different processes are used to produce a smokeless coal the majority of these are based on reducing the volatile content (the gaseous component of the coal that creates the smoke), pulverising, curing and binding the coal / anthracite into a briquette.
Smokeless fuel is more environmentally friendly than traditional house coal, as it emits much less smoke and carbon dioxide out into the atmosphere. Smokeless fuel emits, on average, 80% less smoke and up to 25% less carbon dioxide than ordinary house coal.
What is ‘House’ coal?
‘House’ coal describes any traditional coal that is suitable for burning at home. ‘House’ coal is typically fast burning and can be burnt in open fires and multi-fuel stoves. ‘House’ coal emits greater levels of smoke and carbon dioxide into the atmosphere compared to smokeless coal.
What is the difference between ‘Premium’ coal and ‘House’ coal?
‘Premium’ coal is larger than ‘House’ coal and also provides a stronger heat output whilst burning for a good amount of time.
End result: House coal leaves far more soot deposits and in real terms is a negative economy. Good smokeless coal will give off more heat for longer. Smokeless coal is less harmful to flues.
Brick flues that have burned house coal for many years are often in very poor condition due to the acids deteriorating the bricks and mortar.
It’s best to always advise burning smokeless.
