Fume produced by diesel combustion. According to the principle of diesel engine exhaust shaft, it is known that the diesel engine exhaust shaft in the ventilation drawing is the smoke produced by diesel combustion. The ventilation of the diesel generator room in the basement of a civil building mainly includes the heat dissipation ventilation of the diesel engine unit, the ventilation of the machine room environment and the combustion requirements. Air ventilation. Smoke exhaust mainly refers to the smoke emissions when the unit is running, which is directly discharged to the outdoors.
What should you pay attention to when installing a diesel generator set
The Fengmao diesel generator set is placed in the basement. There are flues in the basement rooms, and the chimney of the Fengmao power generator set is It can be connected directly to the flue, or it can be an exhaust vent. The thing to pay attention to is the problem of smoke seepage.
The heat dissipation and smoke exhaust of the generator set are all related to the diesel tank. Fire inspection only needs to look at these things of the generator set.
1. The installation site must be well ventilated, with sufficient air inlets at the generator end and good air outlets at the diesel engine end. The air outlet area should be more than 1.5 times larger than the water tank area.
2. The area around the installation site should be kept clean, and items that can produce corrosive gases and vapors such as acid and alkaline should be avoided nearby. Fire extinguishing devices should be equipped where possible.
3. When used indoors, the smoke exhaust pipe must be connected to the outdoors. The diameter of the pipe must be larger than the diameter of the smoke outlet pipe of the silencer. The connected pipe should not have more than 3 elbows to ensure that the exhaust pipe is To ensure smooth flow of smoke, the pipe should be tilted downward by 5-10 degrees to avoid rainwater injection; if the exhaust pipe is installed vertically upward, a rainproof cover must be installed.
4. When the foundation is made of concrete, the levelness must be measured with a level ruler during installation to ensure that the unit is fixed on a level foundation. There should be special anti-vibration pads or anchor bolts between the unit and the foundation.
5. The unit shell must have reliable protective grounding. For generators that require a neutral point to be directly grounded, the neutral grounding must be carried out by professionals and equipped with lightning protection devices. It is strictly prohibited to use commercial power. The grounding device conducts the neutral point to be directly grounded.
