Some tips on A Diesel Generator Room Design

As emergency power supply equipment, diesel generator sets play an indispensable role in modern life and production. They can ensure stable power supply in emergencies and keep key facilities running normally. In order to give full play to its role, you must make sure that the room/building you place the generator in complies with all genset room design requirements.

Diesel generator room ventilation system design

Proper ventilation of the generator room is necessary to support the smooth operation of diesel generator and provide an environment for the maintenance/operation personnel so they can work comfortably. The ventilation of diesel generator room is an important part in the design of generator room, especially in a basement environment. Poor ventilation will affect the reliable operation of the generator set.

The exhaust gas of the genset usually is usually effectively discharged through the warm-air pipe to prevent the radiator from conducting heat to the inside of the machine room. And the heat will be removed by the exhaust fan. It’s important to ensure that there is an adequate amount of ventilation airflow be delivered to the generator room. During the operation of the diesel generator, the ventilation volume of the generator room must be at least the sum of the fresh air volume required for the combustion of the diesel engine and the fresh air volume required to maintain the room temperature.

Therefore, critical design parameters such as generator-room temperature, ventilation airflow, ventilation air cleanliness, and air movement must be analyzed during the design process.

Dust removal measures for diesel generator room

If no dust prevention measures are taken in the generator room, the equipment may be damaged. Therefore, while ensuring the ventilation of the generator room, it is also necessary to strengthen the dustproof function. The shutters for air intake and exhaust can be installed to ensure the air quality and air volume of the generator room. Pay special attention to the following aspects:

1. The installation location of the diesel generator should be well ventilated, and sufficient air intake and exhaust must be ensured. The area of the exhaust outlet should be at least 1.5 times the area of the radiator.

2. The installation site must be kept clean. Do not mix with chemical reagents to prevent corrosion.

3. When used indoors, the exhaust pipe of the genset must be guided to the outside, and the pipe diameter should be larger than the smoke pipe diameter of the silencer. When installing pipes, maintain a certain downdip Angle to prevent rainwater from entering. In addition, if the foundation is concrete, the ground needs to be treated horizontally.

4. The enclosure of the diesel generator should be grounded. It is recommended to install lightning protection devices. Do not connect the grounding to the neutral point of the mains power supply.

Improve the Fire-fighting facilities

A fire alarm system should be set up in the generator room. Fire extinguishing equipment should be configured according to the generator size and capacity and the size of the building. If sprinkler systems have been installed in other areas of the building, the generator room should also be equipped with corresponding sprinkler systems.

The ventilation volume of the diesel engine room is calculated as follows:

If the generator room is located on the ground, ventilation numbers should be no less than 3 times under normal circumstances, and no less than 6 times in the event of an accident.

If the generator room is located in the semi-underground, the normal ventilation should be no less than 6 times, and in the event of an accident, it should reach 12 times.

If the generator room is located underground, the normal ventilation frequency should not be less than 12 times. In addition, the number of ventilation in the oil storage room shall not be less than 6 times. Calculation of ventilation volume after a disaster: The ventilation rate of the generator room must be at least five times.

In a word, meticulous design and management of generator room is the basis to ensure the safe and stable operation of diesel generator sets.
