Guide to Install Exhaust Pipe — Diesel Generator
There are two ways to install diesel generator exhaust pipe:
① Horizontal overhead: The advantage is less turning and less resistance; the disadvantage is poor indoor heat dissipation and high temperature in the machine room.
② Laying in the trench: The advantage is good indoor heat dissipation; the shortcomings have many turns and the resistance is large.
The temperature of the exhaust pipe of the generator set is high. In order to prevent the scalding operator and reduce the rise of the temperature of the machine room caused by radiation heat. It is advisable to carry out heat preservation treatment. The heat-insulating material can be wrapped with glass silk or aluminum silicate, which can place a role in heat insulation and noise reduction.
1. Diesel generator exhaust pipes are usually made of unwelded flat steel material, and in some special cases, asbestos cement pipes are used.
2. The exhaust pipe of the diesel generator set shall discharge the gas to an area where will not cause damage or danger, and a protective cap or similar device at the end of the exhaust pipe to prevent rainwater from entering the pipe.
3. The part of the exhaust pipe that passes through the wall is recommended to be thermally insulated to prevent heat from escaping to the wall.
4. The connection of each exhaust pipe of the diesel generator must be well sealed to prevent gas leakage. The connection between flange and gasket is ideal. It is recommended to place a condenser with a socket at the bottom of the pipe.
5. The connection between the exhaust outlet of the diesel generator engine and the pipeline should use elastic hoses, which can alleviate the vibration of the diesel generator engine and the thermal expansion of the pipeline to avoid damage to other components.
6. The exhaust pipe of the diesel generator set also needs 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 with a strong support to prevent it from relying on the diesel generator engine (concentrator, turbo blower), can extend the length of the diesel genset exhaust pipe.
7. When a longer exhaust pipe is required, an expansion joint of an elastic sealing element should be installed.
8. When designing the exhaust pipe, the designer of the diesel generator set manufacturers suggest 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 to conduct thermal insulation treatment on the exhaust pipe.
