Why do generator exhaust systems need to be properly designed?

Generator exhaust systems need to be properly designed to ensure correct engine performance and safe operation. System design has become more complex with the desire to keep emissions low, along with the desire to utilize the heat energy in the exhaust gas.

How do generator exhaust systems work?

Units located inside a building often require the exhaust to be routed up through the roof, up the side of the building, or to a free-standing stack. Generator exhaust systems for years have been fabricated from sections of schedule 40 carbon steel pipe that are field welded, then insulated to reduce surface temperatures.

How should a generator room be designed?

The generator room should have sufficient air circulation to exhaust heat and fuel exhaust. The exhaust chambers should be integrated into the generator design, and the air ducts should be designed to ensure that no gas or air can infiltrate the generator room.

Does a generator room need air circulation?

Adequate ventilation is necessary to ensure that the generator operates efficiently and does not overheat. The generator room should have sufficient air circulation to exhaust heat and fuel exhaust.

Why is ventilation important in a generator room?

The ventilation system in a generator room is critical for maintaining a safe and healthy environment for workers and preventing the buildup of harmful gases like carbon monoxide. This requires careful consideration of factors like airflow rates, duct sizing, and the placement of air intakes and exhausts.

Where should exhaust air be sourced for a generator?

For generators with remote radiators, it is recommended that the exhaust air should be sourced as high as possible and directly above the generator sets. Significant bypass of ventilation airflow directly into the discharge airflow will lead to reduction in cooling effectiveness and elevated temperatures within the room.
