Coal Burner Damage during Operation - How and Why

Erosion and burning out of coal burner tips are normal in a boiler firing coal. Erosion increases with the ash in coal and the property of ash like silica percentage in ash and the nature of silica. Burning out coal nozzle tip will depend upon the organics in coal and its nature. It will also have a very high influence by operating parameters like coal fineness, burner air, swirl maintained in ...

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.

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.
