given pulverizer are a function of coal conduit size, fuel moisture and throat ring flow area. In any case the actual curve must be above a minimum allowable curve. The minimum curve has four components which must be calculated and coordinated: Minimum line velocity, minimum A/F ratio, minimum slope, and the resulting inflection point. The minimum line velocity is the velocity required through ...
04/10/2018 · Moisture content is considered to be additive in case of coal blend. In general, a total moisture content of less than 10 % is preferred for coals used for PCI. At high rates of coal injection, the injected coal/blend becomes a major source of ash and other impurities. An ash content of less than 10 % is normally desired since (i) high levels of coal mineral matter can reduce the performance ...

The important elements of pulverizer performance are fineness, fuel distribution, coal (pyrites) rejects, and primary airflow calibrations. Optimizing pulverizer performance is a prerequisite for optimum furnace combustion. About threefourths of the 13 Essentials are pulverizer, primary air, and fuel line related.

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classifiion. The classifiion function plays the important role of ensuring that only fine particles of the pulverized coal ...
