Abstract:

An evaluation of slag formation was initiated to reduce incinerator slag. A factorial test was used to determine the effect of polymers, primary/secondary sludge ratio, and dewatering equipment on ash fusion temperatures (ASTM D-1857). None of the parameters affected the initial deformation or softening temperatures, 1141 and 1181 °C, respectively. Incinerators experience slag formation several hundred degrees lower than the measured ash fusion temperature test results.

A new test was developed to determine ash fusion temperature. More than seventy 5-cm ash cubes were formed and heated in sets to temperatures of 816, 871, 899, 927, 954, 982, 1038, and 1093 °C. The compressive strength of each cube was measured to determine at what temperature fusion begins. A water spray system was built to control excursion temperatures and slag formation. Supplemental water for cooling excursion temperatures requires approximately 4 times less mass than air. Water injected to the incinerator condenses in the wet scrubber; therefore, there is no additional mass load to the incinerator fan. This process study defined the effect of temperature on slag formation.
