What are the precautions for the design of exhaust system of Diesel generator

exhaust system

The exhaust of Diesel generator is not only harmful but also high temperature, so the design of exhaust system should be paid special attention

If the back pressure of the exhaust system on the engine exceeds the specified value, the performance of the engine will be affected and the maintenance interval will be shortened

The shorter the exhaust system, the smaller the resistance (and back pressure), and the bending parts within the system have a significant impact on the resistance. The maximum allowable resistance of the exhaust system is

R=450 mmH20: All models except SR.6D

600 mmH20: SR

816 mmH20: 6D

The resistance is measured at the outlet of the turbocharger

The recommended material for the exhaust pipe is carbon steel pipe (non galvanized)

1.1 Calculation of exhaust resistance and determination of exhaust pipe diameter

The exhaust resistance is affected by exhaust pipelines and silencers, etc

The exhaust resistance of the pipeline is obtained from the following equation
