Effect of Urban Domestic Wastes on Refractory for Cement Rotary Kiln

Abstract:

The experiment proved the effect of burning urban domestic wastes on alkali-resistant bricks and spalling-resistant high alumina bricks by the Static crucible method. The result indicates that the main erosion mechanism is slag permeable and slag erosion. Burning the waste will emit high temperature gases containing alkali, sulfur and chlorine, and the gases react with refractory materials contribute to the formation of sulfate, chloride and compound salt, which deteriorate and invalid refractory gradually. Through SEM, it is observed that the loose structure of metamorphic layers and easily spalled during thermal stress.
