BW developed Cyclone furnace technology to burn coal grades that are not wellsuited for pulverized coal combustion. The ash from these coals has a very low melting temperature. This molten ash would normally be deposited on all downstream heat transfer surfaces, causing severe slagging and fouling with resultant negative impact on unit ...

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
Babcock and Wilcox Boiler was discovered by George Herman Babcock and Stephen Wilcox in the year 1967. This is a water tube boiler, used in steam power plants. In this type of boiler, water is circulated inside the tubes and hot gases flow over the tubes.
A high pressure watertube boiler (also spelled watertube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steamgenerating smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the waterfilled tubes ...

Ball Mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two.
Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm ( in). Coal burns in suspension, like the combustion in an oil or gasfired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil

Combustion Engineering, Babcock Wilcox, and Riley Stoker Corp. are major manufacturers of coal pulverizing equipment. The four most common types of coal pulverizers are: BallTube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube.
