A Comparison of Three Types of Coal Pulverizers

Vertical Roller Mill The vertical roller mill (VRM) shown in Figure 4 is an air swept, mediumspeed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulicallyloaded grinding pressure through three grin ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal

A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only twothirds of the ball mills.

Pulverizer Vibration Issues

Pulverizer Vibration Issues

Much of the improvement can be traced to the need to achieve higher fineness levels. As we have mentioned before, our goal for optimum combustion is to attain a minimum of >75% passing 200 Mesh with <% remaining on the 50 Mesh at pulverizer full load. Higher fineness at full load can cause extremely high fineness at lower coal flows.

How to Run a Coal Fired Boiler at the Best Efficiency

How to Run a Coal Fired Boiler at the Best Efficiency

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
