How does the centrifuge work?

Jul 01, 2020


In the water vapor system, the water supply is heated to a certain temperature in the heater, and then it enters the economizer through the water supply pipe. After further heating, it is sent to the pot barrel. After mixing with the pot water, it travels down the descending pipe to the inlet header of the water cooling wall.

The water absorbs the radiant heat of the furnace in the water cooling wall tube to form the soda mixture, which reaches the boiler barrel through the riser and is separated by the soda water separation device.

The separated saturated steam flows from the upper part of the drum to the superheater, which continues to absorb heat into superheated steam at 450℃, and is then sent to the steam turbine.

In combustion and smoke air systems, the blower feeds air into the air preheater and heats it to a certain temperature.

In a coal mill, pulverized coal of a certain fineness is carried by a portion of hot air from an air preheater into the furnace through the burner.

The pulverized coal and air mixture emitted by the burner is mixed with the rest of the hot air in the furnace and burned, giving off a large amount of heat.

The hot flue gas after combustion passes through the furnace, cinder bundle, superheater, economizer and air preheater in sequence, and then goes through the dust removal device to remove the fly ash, and is finally sent to the atmosphere by the induced draft fan.
