Coal pulverizer downtime can be a major factor in reducing overall plant availability and reliability. Recommended Filtration Upgrade to Achieve Total Cleanliness Control (See diagrams on back page) The majority of pulverized coal particles are in the 430µm range, with 70% of these particles smaller than 10µm.
In order to protect the coal pulverizer lube system components, Pall recommends maintaining a fluid cleanliness level of ISO 16/13 or better. This can be accomplished through the use of Ultipleat® SRT AS grade (ß12 (c)≥ 1000) or finer filters. Ultipleat SRT filters, with their high particle removal efficiency and dirtholding capacity, are
