The technology of MAN BW Diesel Emission Control

摘要

This paper has been published to provide information about MAN B&W diesel's deliberations and viewpoints in connection with emission control of two-stroke engines. MAN B&W Diesel has been researching and working on methods for more than 15 years. The methods include engine component modifications and exhaust gas after-treatment. This paper describes the components in the exhaust gas, the methods used in emission reduction and the results obtained. The results are illustrated by graphs and figures from two separate NO_x control case stories. In the first case, water emulsification led to a 50% NO_x reduction, and in the second case, Selective Catalytic Reduction (SCR) led to a 95% NO_x reduction.
