Airfuel ratio - Wikipedia

Airfuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion, gas or vapour explosion or in a thermobaric weapon). The air-fuel ratio determines whether a mixture is

Coal-mill optimisation in coal-fired power stations aids

The vertical spindle mill crushes coal by feeding it between a grinding roller and either a bowl, table or ring at the bottom. Coal enters via the coal feed and falls into the grinding zone, where it is crushed by the grinding wheels. The coal particles are spun outwards by the rotation of the grinding table, and transported by the incoming heated air feed to the classifier, which separates
