How to Install the Exhaust System of Diesel Generator

Jul. 02, 2021

When there is more than one unit in the machine room, remember that the exhaust system of each unit should be designed and installed independently.Never allow different units to share one exhaust pipe, so as to avoid abnormal movement caused by different exhaust pressure of different units during unit operation.

 

The working definition of exhaust system of diesel generator set refers to the exhaust pipe connecting the engine exhaust port to the engine room after the diesel generator set is installed in the engine room, including muffler, bellows, flange, elbow, gasket and exhaust pipe connecting the engine room to the outside of the engine room.

 

The number of elbows and the total length of the exhaust pipe should be reduced as much as possible in the exhaust system of the generator set, otherwise the pressure of the exhaust pipe will increase. It will cause too much power loss, affect the normal operation of the unit and reduce the normal service life of the unit.The exhaust pipe diameter specified in the technical data of diesel generator set is generally based on the total length of exhaust pipe of 6m and the installation of at most one elbow and one muffler.

When the exhaust system has exceeded the specified length and the number of elbows in actual installation, the exhaust pipe diameter should be increased appropriately. The increase depends on the total length of the exhaust pipe and the number of elbows.The first section of pipe from the main exhaust pipe of the supercharger of the unit must contain a flexible bellows section. The corrugated pipe has been supplied to customers randomly. The second section of the exhaust pipe should be elastically supported to avoid unreasonable installation of the exhaust pipe or additional side stress and compressive stress caused by relative displacement of the exhaust system due to thermal effect during the operation of the unit. All supporting mechanisms and suspension devices of the exhaust pipe should be elastic.

 

When there is more than one unit in the machine room, remember that the exhaust system of each unit should be designed and installed independently.It is not allowed for different units to share one exhaust pipe, so as to avoid abnormal movement caused by different exhaust pressure of different units during unit operation, increase exhaust pressure and prevent waste smoke and exhaust gas from backflow through the common pipe, which will affect the normal power output of the unit or even cause damage to the unit.
