The Storm Approach to Coal Pulverizer Optimization

raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line). This is pretty standard. Now, take that same pulverizer and provide fuel that is 40 HGI, still ¾" top size and still 7% moisture, but increase the fineness requirement to 80% passing a 200 mesh sieve.

Pulverizer - Wikipedia

With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels .

Pulverizer Performance and NOx Emissions

Coarse coal (poor fineness) results in less total surface area on the carbonaceous solids from coal. Higher fineness levels and consequently smaller particle sizing of carbonaceous solids increases the total surface area of particles to be oxidized and allows the chemical reaction of combustion to be completed more quickly.

Effect of Operating Variables on Fuel Ash Corrosion in Boilers

On the fuel side, burner line resistances should be balanced to maintain uniform coal flow to each burner. Coal feeders should be calibrated and adjusted to provide uniform coal flow to each pulverizer. Coal fineness Low pulverizer fineness can also cause problems associated with delayed combustion.

Decreased coal fineness and poor fuel balance associated with decreasing fineness levels. Primary air flow must be accurately measured and controlled. We prefer utilization of a flow nozzle (shown in illustration below) when possible. If flow nozzles are not installed, primary air flow measurement accuracy must be within ±5% of actual flow.
