摘　　要：MAN B&W 6S50MC-C MK7型主机在试航中耐久试验时发现主机排气系统背压有超标现象,通过对排气系统组成分析及有关废气参数和排气系统中的各管段的摩擦系数等计算,进一步分析了工况调整不理想状态下背压超标的原因,提出了改进废气流通的方案.The MAN B&W 6S50MC-C MK host found that the back pressure of the exhaust system of the host was exceeded during the endurance test during the trial.Through the analysis of the exhaust system composition and the calculation of the exhaust gas parameters and the friction coefficient of each pipe in the exhaust system.This paper further analyzes the causes of overpressure under unsatisfactory condition adjustment,and puts forward a scheme to improve the muffler to increase the exhaust gas flow.

关 键 词：排气系统 背压 摩擦系数
