How To Maintain Fuel For Diesel Generator Sets
By: Patti Dinneen
A majority of generator systems feature diesel engines. Unfortunately, stored diesel fuel can become contaminated over time, and using degraded fuel (or even simply leaving it in the generator when not in use) can damage the equipment over time.
Ultimately, this can mean that backup generators may not function properly (or at all) when needed. And a utility outage is not when you want to find out about the ill effects of poor fuel maintenance. The maintenance and testing of a generator's diesel fuel storage is essential, even more so for standby generator systems where the fuel may remain unused for months.
This blog post will briefly discuss the sources of fuel degradation, as well as what you can do to reduce your chances of fuel degradation.
What Are The Main Sources Of Fuel Degradation?
Gelling: This can be a problem this time of the year because diesel fuel freezes at a much higher temperature than most other fuels. Standard diesel can freeze at any temperature below 32 F, which will inevitably lead to gelling and/or clogged fuel pipelines.
Microbes: One of the threats of water is that it can harbor microbes, which create sediment that can pose a threat to filtration systems. These microbes can and do exist in fuel tank water bottoms.
Past Shelf Life: Like many products, diesel fuel has a certain shelf life and can begin to degrade after six months. After two years of inactivity, degradation can cause diesel fuel to become useless. The degradation of fuel can affect other aspects of your generator, including flash and cloud points, distillation, and can also impair engine performance.
What Can I Do To Reduce Or Eliminate Fuel Degradation?
There are five main fuel services available to help you ensure that your diesel fuels allows the engine to run as necessary:
These five fuel services should be incorporated into your planned maintenance schedule. If you have not taken the time to speak with a generator set serviceman, do so before any major issues arise.
