Direct-Mount Seal Pressure Transmitters For Pulverized Coal Processing
By ABB Measurement & Analytics

Many coal-fired power plants measure various pressures associated with their coal pulverizing mills. A certain "sweet spot" of pressure indicates smooth and proper operation of the mill, as well as the exhauster ductwork. If the pressure drops, the mill could be plugged or the fuel supply cut short. Higher than normal pressure may indicate plugging of downstream coal ducts leading to the furnace. Improper pressures often lead to flame instability, productivity losses, and pollution.
