Recent years, the action for the low-carbon society becomes active all over the world. NH3 has potential to become the free-carbon energy source. In SIP project, that Cabinet Office started, we work on the technology development applying NH3 to the field of industrial furnace (SIP: Strategic Innovation Promotion Program).

In this study, we evaluated the effect of NH3 use in the cement clinker manufacturing process. Cement manufacturing is one of the fields of industry to exhaust large amounts of CO2. As past works, we studied for the reduction of heat consumption rate, troubleshooting and so on by using kiln operation analysis tool, KilnSimu. This time, we applied the KilnSimu analysis technology to this work.

For some parameters using in KilnSimu, we referred to the actual plant data. About the clinker reaction kinetics under the NH3 combustion atmosphere, we gave the element experiment.

By KilnSimu analysis, we were able to evaluate the quantitative influence at using NH3 for the actual operation. When using NH3, the possibility of the influence on heat consumption rate was predicted. We also report the improvement plan about this.
