The objective of the present study is to develop an innovative diagnostic and reduction system of fouling, which can detect and reduce fouling. We developed apparatuses by U-coefficient and ultrasonic methods for fouling reduction and diagnosis. The measured values with the diagnostic system was compared with the amounts of the scaling generated by the simulator

Fouling causes serious maintenance problems on heat exchanger tubes and process facilities. To avoid such fouling problems, numerous efforts have been tried, e.g., diagnosis of fouling, reducing and eliminating the fouling, etc.. The objective of the present study is to develop an innovative diagnostic system of fouling, which can detect the scaling attached to the wall non-homogeneously. The performance of the diagnostic system has been evaluated with a scaling simulator that generates scaling on tested tube wall. The measured values with the diagnostic system were compared with the amounts of the scaling generated by the simulator.

In this paper, we study NH₃ De-NOx SCR (Selective Catalyst Reduction) technology of marine engine for low temperature (below 250 C) exhaust gas.<br/> This technology can remove max 80% NOx in exhaust gas under low gas temperature (below 250C) condition using combined non-thermal Plasma and Ammonia SCR method.<br/>
