... such circumstances, volatile compounds of sulfur, namely sodium and potassium pyrosulfates (Na 2 S 2 O 7 and K 2 S 2 O 7 ), with a low melting point (450 °C, or 840 °F), form. These compounds volatilize at high temperature and condense as a liquid on the relatively cooler surface of the waterwall tubes ( Ref 6.31...
