bed scrubbers, spray tower scrubbers, and tray tower scrubbers. Venturi scrubbers may also function as gas absorbers; however, they are usually designed for control of particulates rather than acid gases or SO 2. Gas and liquid flow through an absorber may be cocurrent flow, counterflow, or crossflow.

The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transported from the mill outlet to the exhauster. From the exit of the exhauster, the coal and air mixture flows to the distributor box or riffle. From the riffle, the coal and air flow to the boiler burner panels.

Baghouse Wikipedia

A baghouse, also known as a baghouse filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air. Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use baghouses to control emission of air pollutants.

Boiler Performance and Mill Outlet Temperature Bright Hub Engineering

Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coalair mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 degree centigrade, the upper limit is ...

pulverized coal at the mill outlet is 30%, the gas temperature required at the mill inlet is considered to be approximately 450°C. The evaporation of water in raw coal increases the vapor concentration in the gas at the mill outlet and consequently the O2 level of the primary gas in the burner is expected to be decreased to approximately 9%.
