Abstract
The aim of this study is to examine the distribution of K, Mg, Si, Ca, and P to the ash and combustion gas during the combustion of ground cedar nut shells in an air atmosphere. The cedar shell combustion process took place in a furnace at a temperature of 830 +/- 25 degrees C. The composition of the ash obtained from cedar shell combustion was assayed using a Thermo iCAP 6500 Duo ICP plasma spectrometer. Potassium oxide had the largest share of ash (32.6 wt%). The presented results of equilibrium calculations in the temperature range of 800-1200 degrees C represent the use of cedar shells as a fuel for the circulating fluidized-bed furnace. Based on computation made in the FactSage 6.3 program, it has been demonstrated that only potassium vaporizes in the form of the KOH(g), K2SO4(g), and KCl(g) compounds. Most silicon and magnesium are contained in the ash in the form of Mg2SiO4(s) in the temperature range of 800-1200 degrees C. Calcium passes into the ash exclusively in the form of Ca3HP3O13 (hydroxyapatite), if T860 degrees C, or calcium orthophosphate(V) - above 860 degrees C. Phosphorus is present in the ash in the form of many compounds, such as Mg-3(PO4)(2)(s), Ca5HP3O13(s), Ca-3(PO4)(2)(s), and Na3PO4(s).
