Power generation industry studies have shown that pulverized coal power plants are an area where improved equipment reliability is essential. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizer-related problems.
In a coal-fired power plant, the coal pulverizer is critical for fuel processing. It is important to operate the pulverizer properly following the OEM specified procedure and NFPA code requirements. The increased use of highly volatile sub-bituminous coal such as Powder River Basin (PRB) coal has further emphasized
Figure 4 shows the configuration of such a system, as installed both at AES Corp.'s 126-MW Westover Plant in Johnson City, N.Y. (see POWER, October 2006) and Savannah Electric's McIntosh Plant. 4.
unit, in which coal is ground via a pulverizer to a fine powder and then combusted in a burner. 1 PC units are the most prevalent technology in ... A power plant boiler, heat-transfer equipment, and auxiliary com-ponents can weigh nearly 11,000 metric tons, requiring the equivalent
Abstract. Power plant boiler fuel demand is transmitted as a coal feeder speed demand to a coal pulverizer control. A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or …

The pulverizer configuration usually found in most coal-fired power generation plants is the vertical air swept design, although there are a number of ball tube pulverizers still in service.
Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.. B&W's pulverizers, found at power stations throughout the world.

Typical Temperature of a Pulverizer – Inlet Temperatures will high regardless of pulverizer manufacturer with high moisture coal. 130°F – 140°F. 140°F – 160°F.
This increases the likelihood of a pulverizer or coal pipe fire/puff to occur. 10. Operating a pulverizer with too high an output fineness is considered less then optimal as increased fineness results in lower pulverizer capacity and higher pulverizer motor power consumption.
A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions. …
Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially available in different sizes known as "Run of Mine," "stoker," "slack," etc. depending on their size. ... The pulverizer does the powdering or the pulverizing. Pulverizers come in different models and are a very important ...
20. 13.1.Fineness Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. …
A pulverizer performance program, combined with a sharp focus on maintaining proper air/fuel ratios, fuel fineness, and fuel balance, can reduce heat rate.
