STORM TECHNOLOGIES, INC. October 2015 Diagnosing Pulverizer Performance Whether the issues are slagging, O, flyash LOI, furnace tube wastage, superheater/reheater tube metals overheating or cinder carryover into the SR, usually the "root cause" if the pulverizers are the culprits, is one of three factors: 1. Nonoptimum coal fineness 2.
case on wall fired boilers, the high primary airflow also reduces the coal fineness, which impacts the as well as the fuel distribution. Originally the fineness was found to be about 65% passing a standard 200 mesh sieve. Storm Technologies goal was to achieve fineness results of

superheater pendants. Coal fineness, when sampled from one of 8 pipes always would show 70% + passing a 200 mesh sieve. Yet the flyash was poor, and fuel balance appeared poor. Later, by the STORM® approach, using the STORM® Isokinetic Coal Sampler, all eight pipes were sampled and the fineness samples, weighed and sieved for all eight pipes.
While renewable energy has undergone wide and rapid deployment, coal is still expected to be the main source of fuel for producing base load power in the near future. This is because coal reserves are expected to last for the next century and its cost is still relatively cheap. However, the emissions from coal combustion are a major environmental concern.
