Abstract. Commercial coal pulverizers vary greatly in their performance. While there are two principles of attrition and impact on which pulverizing mills are based, there are such radical differences of design as to raise the question of correct fundamentals. Guarantees are given on performance when the engineering problems are difficult of …
The Uni-Sampler is a coal sampler that was developed to retrieve coal samples for testing from coal trucks, rail cars, and river or ocean barges by using an auger bit. Depending on the customer need, the Uni-Sampler can be manufactured as a stationary pier-mounted unit, a mobile unit, a rail-mounted unit, or a boat/barge mounted unit.

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.
Often, we visit plants that perform pulverizer maintenance based on operating hours, or fuel tons throughput. In our view, pulverizer maintenance should be driven by periodic tests of pulverizer performance. The important elements of pulverizer performance are fineness, fuel distribution, coal (pyrites) rejects, and primary airflow calibrations.
STORM's High Velocity Thermocouple (HVT) Probe is ideal for measuring flue gas constituents and temperatures inside the furnace. By utilizing a water-cooled jacket, measuring flue gas temperatures up to 2,500 o F is possible, where a non-cooled probe would simply melt. Standard HVT Probes are able to be used through an access port as …

Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.
In ducts A and B, the total pressure, static pressure and gas temperature were measured, and pulverized coal samples were obtained at these measurement points. 10 s of coal sampling at each grid point was applied at isokinetic conditions that were specified as the measured static pressure, total pressure and temperature.
