The joints of each exhaust pipe of the diesel generator set must be well sealed to prevent gas leakage. The connection between the flange and the gasket is ideal. It is recommended to place a condensation collector with a socket at the bottom of the pipe.
The connection between the exhaust outlet of the diesel generator set engine and the pipeline should use elastic hoses, which can alleviate the vibration of the diesel generator set engine and the thermal expansion of the pipeline and avoid damage to other components.
The exhaust pipe of the diesel generator set also needs to have a flange (not the flange on the unit), so the exhaust pipe must be fixed on the wall or the top of the machine room and have a solid support to prevent It relies on the diesel generator engine (collector, turbine blower) to extend the length of the diesel generator exhaust pipe.
When a longer exhaust pipe is required, an expansion joint with an elastic sealing element needs to be installed.
When designing the exhaust pipeline, designers of diesel generator manufacturers recommend that the exhaust pipe should be installed away from the air filter of the diesel generator engine to prevent the machine from absorbing hot air or causing damage to the exhaust. The tubes are thermally insulated.
When using multiple diesel generator sets, it is recommended not to install all the exhaust pipes on the same pipe, because when some units are running and other units are shut down, problems will occur: the exhaust gas will enter inside the unit that is not in use, causing damage to the unit.
The exhaust back pressure of the engine has a great impact on the power and heat exchange generated by the unit. If the back pressure value is too high (measured at the exhaust outlet of a naturally aspirated engine or at the turbine outlet of a turbocharged engine), the power of the diesel generator set will decrease, the exhaust temperature will be too high, thick smoke will be produced, and the increase in The consumption of fuel causes overheating of cooling water, failure of lubricant function and damage to other engine components.
If you encounter other situations, please consult the diesel generator manufacturer in time.
