(549g) Evaluation of the Cement Clinker Fired in the Combustion Furnace of Heavy-Oil and NH3
First, we fired the clinker in the atmosphere-controlled electric furnace, calculated the reaction rate of CaO which is the main oxide in clinker by Arrhenius type kinetic model. As a result, it was found that the reaction rate of clinker was not influenced by the atmosphere conditions and was dominated by the temperature conditions.
Next, we fired the clinker in the 10 kW furnace under only heavy-oil combustion and mixed combustion of heavy-oil and NH3, identified mineral composition by X-ray diffraction (XRD)/Rietveld analysis, carried out the strength test for cement was made from the clinker. As a result, it was confirmed there was no difference in mineral composition and strength of clinker.
