Generator installation specifications for air inlet and exhaust shafts

What is the intake system of a diesel generator set?

The intake system of the diesel generator set is equipped with dry air filter and air filter and air resistance indicator, with exhaust gas turbocharger, full intake and guaranteed performance.

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.

Who designs and installs a generator exhaust system?

The proper design and functionality of a generator exhaust system falls on the responsibility of the engineering firm of record. If a field fabricated system is being utilized, the design and installation of the system must be a collaboration between the engineering firm and the installing contractor.

How to choose a diesel generator intake pipe?

Diesel intake pipes for diesel generator set should be avoided as far as possible and the number of bends should be reduced, or use a large arc transition. The inner diameter of the intake pipe should not be less than 200mm, and the inner wall of the pipe should be smooth without soldering slag particles.

What temperature should a field fabricated generator exhaust be insulated?

To protect potential personal contact with the system, the outer shell temperature must be below 140°F. These temperature calculations can and should be performed by the UL listed manufacturer based on specific product design criteria. Field-fabricated generator exhaust also requires insulation.

What are the code requirements for generator exhaust?

To investigate code requirements for generator exhaust it is important to start by reviewing the International Mechanical Code® (IMC). Section 915 of IMC 2018 regarding Engine and Gas Turbine-Powered Equipment and Appliances is applicable stating: 915.1 General.
