Lean Coal Burner In Boiler

Coal Burner Damage during Operation - How and

2021-2-19 · 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
