Study of corrosion forms on metal surfaces at combustion of coal with high salt content

Анотація

The main source of the formation of deposits (slagging) on the heating surfaces is sulfates of alkaline, alkali-earth metals and iron, and the main cause of under-deposit corrosion of metal surfaces is chlorine compounds, primarily hydrogen chloride. The complexity of the processes of slagging and corrosion, which occur when using various fuel raw materials, determine the need for detailed study of each type of fuel, especially one with an increased content of salts (Na2O in ash ≥2 %).
