Generator Air Intake and Exhaust Regulations
The term ‘specified generator’ covers an individual generator or a number of generators if they’re: 1. on the same site 2. operated by the same operator 3. for the same purpose (generating electricity) Generators are still classed as operating for the same purpose if they’re: 1. using different fuels or technologies 2.. . Both the MCPDand specified generator regulations can apply to generators. If your site includes a medium combustion plant that generates electricity you must check if your generator: 1. is. . Specified generator controls, unless excluded, apply to generators with a rated thermal input between 1MWth and 50MWth. They also apply to generators less than 1MWth, if they: 1. have a capacity agreement or an. . These generators are excluded from specified generator controls. For a MCP that generates electricity you must also check if the MCP is excluded from the MCPD controls. . Some operators have more time to get their permit in place and comply with permit conditions (this is called a transitional arrangement).. [pdf]FAQS about Generator Air Intake and Exhaust Regulations
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.
Does high temperature pressurized generator exhaust meet code requirements?
UL listed products utilized for high temperature pressurized generator exhaust meet code requirements. 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:
Does engine generator set meet emissions requirements?
Engine generator set shall meet emissions requirements as determined by AHJ. Type your questions, comments, feedback in the WebEx Q&A box. We will get to as many questions as we can
Do I need a permit for a generator?
Both the MCPD and specified generator regulations can apply to generators. If your site includes a medium combustion plant that generates electricity you must check if your generator: Check using the guidance on Medium combustion plant: when you need a permit. These generators are excluded from specified generator controls.
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.
Do generators have to meet ELV requirements?
The emission limit values (ELVs) and air quality standards specified generators must meet, including the deadlines for complying. If your generator’s capacity is more than 1 megawatt thermal you may also need to comply with the medium combustion plant ELV requirements.

What are the functions of generator exhaust
A gen set exhaust system must collect gases from engine cylinders and discharge them as quickly and silently as possible.. A gen set exhaust system must collect gases from engine cylinders and discharge them as quickly and silently as possible.. A generator set exhaust system performs the same basic function as any other exhaust system - it provides a pathway for exhaust gases to escape into the air.. Auxiliary systems such as the exhaust system and cooling system play important roles in maintaining fuel economy, reducing emissions, regulating temperature, and improving cooling efficiency. [pdf]FAQS about What are the functions of generator exhaust
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.
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.
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 diesel generator work?
The diesel generator works on the principle of the diesel cycle. The diesel cycle consists of four strokes: intake, compression, power, and exhaust. During the intake stroke, air is drawn into the cylinder. During the compression stroke, the air is compressed, which raises its temperature.
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.
