The performance of a static coal classifier and its controlling .

In power generation from solid fuel such as coal-fired power plants, combustion efficiency can be monitored by the Loss on Ignition (LOI) of the pulverised fuel. It is the role of the pulveriser-classifier combination to ensure pulverised fuel delivered to the burners is within the specified limits of fineness and mass flow deviation.
