In late years the discharge of the CO2 became the very big problem. The combustion of the fossil fuel in particular exhausts much CO2. Our project team (SIP) is intended to reduce CO2 by using NH3 (10%~30%) in substitution for heavy oil. The ‘SIP energy carriers’ was launched in 2014 (SIP: Strategic Innovation Promotion Program). Ammonia direct combustion team was formed. We conducted a co-research program with Osaka University in this project. We performed experiment of heavy oil – NH3 mixed combustion in the 10kW furnace. As the results, we obtained much experimental data. When we were combusted NH3 and…

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…
