Fluidal ashes – properties and application

Abstract

Technology of fluidal combustion creates ashes which differ significantly on ones created in conventional boilers. The main feature of fluidal ashes is presence of products of exhaust desulfurization and of not used sorbent in addition to significantly different mineralogical composition of aluminosilicates occurring from significantly lower combustion heat. The fluidal ash has many interesting properties from which its relatively big chemical activity is the most significant. While many potentially promising areas of applying these ashes still wait for development it seems important, still storing its significant amount, to keep possibilities of future recovery and application of stored ashes. The final report analyzes several such possibilities with chosen examples. Summing up, the investigations conducted so far were concentrated main
