What is a diesel generator air intake & exhaust system?

The diesel generator air intake and exhaust system (DGAIES) provides the diesel engine with combustion air from the outside. The combustion air passes through a filter and silencer before being compressed by a turbocharger and cooled by the coolant system before entering the individual cylinders for combustion.

How does a single shaft gas generator work?

Compression power is provided by turbine section’s power output. A single-shaft GT operates at the speed and firing temperature to keep itself self-sustained (frequently called a “jet”, or “gas-generator”, for convenience).

What temperature does a generator exhaust system emit?

Generator exhaust systems must also be engineered and properly installed to accommodate thermal expansion. Generator exhaust systems emit exhaust at temperatures anywhere from 500°F up to 1300°F depending on the unit size, manufacturer, and type of fuel burned.

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 does a gas generator work in a jet engine?

, and leading to the turbine section. In jet engines, the responsibility of a gas generator is to produce a high-pressure, high-temperature stream of combustion products (predominantly air), which are allowed to expand down to (ideally) the local

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.
