Furnace Knowledge of Coal Fired Boilers--ZBG

Furnace classification of coal-fired boilers: (1) Cylindrical hearth that uses air flow to rotate coal particles at a high speed and burns intensely is called a cyclone furnace. (2) The hearth where the solid fuel is put on the grate for fire-bed combustion is called the stratified furnace, also known as the fire-bed furnace.
