Oct 04, 2018· An ash content of less than 10 % is normally desired since (i) high levels of coal mineral matter can reduce the performance of pulverizer performance and throughput, and increase wear in the pulverizer and conveying pipelines, (ii) there are lower slag volumes and hence there is a better thermal efficiency, (iii) less energy is needed to melt ...
Pulverizer Product Fineness: Fineness of pulverized fuel is one of the pulverizer sizing criteria, as discussed earlier. Unit Turndown: The design of a pulverizer system determines the turndown capability of the steam generator. The minimum stable load for an individual pulverizer firing coal is 50% of the rated pulverizer capacity.
Aug 11, 2008· In fact, this will provide a standard guideline over the operational adjustment and maintenance requirement of the pulverizer. The base capacity is a function of grindability; fineness requirement may vary depending on the volatile matter (VM) content of the coal and the input coal .
The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
The crushed coal is fed to the drier from the raw coal bunker by gravity. The drying of coal is effected either by using hot gases, preheated air or bled steam. The dried coal is fed to the pulverizer with the help of feeder. The pulverized coal is carried from the pulverizer .
Transportation of pulverized coal from the pulverizer to the burner. • Provides the necessary heat requirement to facilitate evaporation of surface and inherent moisture in the coal. After coal and air is mixed at the pulverizer the resulting mixture of air/coal is typically called dirty airflow. The use of air to transport coal .
