Abstract
In recent years, one of the important needs of the waste incinerator facilities was to ensure their sustainability, which can be achieved by doing both stable operation and cost reduction. Despite of the shortage of the highly experienced operators in the facilities and the seriousness of the response to the contingencies, both stable operation and cost reduction which contributed to the reduction of CO2 emission and prevention of global warming, were ultimately required. This condition made the remote monitoring support systems become more indispensable than ever. Based on this situation, we build the remote monitoring /operation support systems utilizing the cloud system were built, the operation data were collected and processed altogether, and finally the obtained know-how was expanded and utilized for optimizing other incineration facilities. This effort was made by a joint research with Yokohama City. The result, it was confirmed that during the operation in 4 days, the manual intervention from the operators can be significantly reduced by the highly automated operation. Moreover, the amount of the generated steam for power generation, the CO and NOx concentrations in the flue gas, exhibited the equal performance compared to that of the normal operation. In the future, the highly automated operation will be conducted for a long period, with the aim of further improving accuracy and reducing the number of manual interventions, taking into consideration fluctuations in waste quality due to seasonal changes.
