  • The Storm Approach to Coal Pulverizer Optimization

    All coal pipes (and flows to all of the burners from each respective pulverizer) should be balanced and within /- 2 of the mean flow. Perform a seal air check. Begin the normal pulverizer start sequence. Once normal coal flow is applied to the mill a full mill test should be conducted. This should include isokinetic coal sampling and dirty
