Zhu Yuanqing, Feng Yongming and Zhou Song of the School of Power Engineering of Harbin Engineering University took the lead in undertaking the “optimization of the performance of low-speed marine high-pressure SCR system and its matching technology with the hostâ€, and won the focus of the 2016 national key R&D plan “Research on the causes and control technologies of air pollutionâ€. The special youth project was established and launched. The project aims to help break through the key technologies such as denitration system and its matching design with high-power diesel engines, and help China's ship pollution emission control technology and demonstration.
The “Optimization of Performance of High-Voltage SCR System for Marine Low-Speed ​​Machines and Its Matching Technology with Hosts†project is aimed at the International Maritime Organization's relevant nitrogen oxides, sulfur oxides and carbon dioxide emission reduction standards and requirements, and is implemented in conjunction with the Ministry of Communications's Air Pollutant Emission Control Area. The plan and plan are to optimize the design performance and performance of the existing low-speed diesel engine high-pressure SCR system. The project focuses on breakthrough design technology, supercharger bypass drive power turbine power generation technology and waste gas low temperature sulfuric acid treatment technology, and seeks to solve the new methods and new ways to solve the shortcomings of high cost and large volume of existing ship exhaust gas combined desulfurization and denitration technology. The multi-objective optimization, interlocking control and coordinated matching between the low-speed diesel engine high-pressure SCR system and the main engine and other post-processing devices breaks the monopoly of the global ship supporting market, which is almost completely expensive for foreign ship post-processing products.
