Diesel Fuel Management For Standby Generators – A Complete Approach

Diesel Fuel Management For Standby Generators – A Complete Approach

Maintenance programs are the most common phenomenon for generators. Most of the standby generators require bi-annual or annual maintenance so that they can work effectively. Usually, people give more importance to the management of the generator’s parts and ignore diesel fuel management.

Moreover, most of the people check whether the fuel tank of the generator is full or not. But they don’t understand that fuel itself has its own self-life. Unfortunately, no one understands that fuel management is also as important as component management.

Here, in this article, we will learn how Diesel fuel management for the standby generator is done as diesel is the most common fuel used in generators. But before discussing the diesel fuel management we need to understand about standby generators first.

Standby Generators

In a simple language, you can say it is a backup electrical system that operates automatically. It is beneficial for emergency backup electrical power.

During a power outage, a standby generator detects the outage immediately and supply electrical power within seconds of utility. After utility power returns, the automatic transfer switch transfers the electrical power load back to utility and commands the standby generator to shut off. Then the standby generator returns to their standby mode, where it starts waiting to next outage.

Automatic standby generator systems are spatially used by building codes for critical safety systems, for example, fire protection systems, high-rise buildings, medical and life support equipment or standby lighting.

It is also used for residential, providing backup electrical power to security systems, HVAC (Heating, Ventilation, and Air Conditioning) and household appliances such as water heaters, stoves, and refrigerators.

Let’s Know more about Diesel Fuel Management

Maintaining generators are commonly a critical component. Every machine needs maintenance to increase machine life cycle. In some cases, most generators require simple visual monthly inspections. Others require specific steps to maintain every two years. And some generators need maintenance in the bi-annual to annual range.

Diesel fuel maintenance is not given much attention and it is not a part of a maintenance program because generators may receive required maintenance themselves. It is hard to maintain and monitor the integrity of the fuel, especially when the diesel fuel stored in tank long-term. It could be the biggest concern.

When the diesel fuel life cycle creates the problems. It can’t be understood easily. So, it left to the expert to manage the underlying problem. The professional has to fix and mitigate the risks.

A simple and unique mistake is using a low grade of diesel or without testing the quality and condition of the fuel. It can cause your generator with numerous failures. And there is one more mentality that after purchasing the stocks of fuel, it is just left for when it’s needed. This type of negligence can cost businesses money, in terms of lost productivity and unreliability can do serious damage to a firm’s reputation.

Let’s read about the importance of diesel management for standby generators.

Why it is important for standby generators?

Diesel management is necessary for all kinds of generators because it can help to increase the life of a generator. If the fuel management is done properly then the generator can give a better backup result.

A bad fuel can affect the efficiency of the generator and also doesn’t provide a better result. A cleaner diesel fuel can help to maintain the integrity of the machine. The quality of diesel fuel can help in determining whether the generator is reliable or not.

Reasons behind the contamination of diesel fuel?

Generally, this type of fuel should only be stored for 6 to 12 months. In the best of circumstances, it may be possible to maintain it a little longer. To increase this length, the fuel must be clean to begin with, kept cool at approximately 70 ° F, maintained properly, and treated continuously with stabilizers and biocides.

When this does not happen, hydrolysis, microbial growth, and oxidation can occur, which damages the quality of the fuel. For example, when diesel comes in contact with water, it causes fuel breakdown. This includes condensation accumulation of water droplets hitting the fuel surface from the tank roof. Microbial growth creates acids that can degrade fuel and stop the flow of liquids as the tank clogs which will soon leave you in search of a new engine.

And, finally, oxidation occurs as a chemical reaction when the fuel is in contact with oxygen. This risk occurs immediately when the product leaves the refinery – the process may be slow but it does not stop. Oxidation can create high acid values, which can lead to the formation of sludge and sediment.

Cleaning Diesel Fuel

Without maintenance, diesel fuel can last for 6-12 months and even longer in some conditions, but it certainly does not last forever. In the past years, diesel fuel had an exceptionally long shelf life, but new EPA regulated diesel fuel has changed those conditions.

It could be cleaner on the CO2 output but the unintended result was that we now have fuel that has many additives that can’t fit with engines. This is required much more management and monitoring than ever before, the reason is that it is more susceptible to bacterial growth and sludge build-up.

All the diesel fuel gets spoiled over time if it stored longer inside of a storage tank. When you run the diesel power generator with the dirty diesel fuel, it can harm your generator’s engine, the result of it can be sludge build-up, clogged filters, and numerous other problems. The sludge build-up and clogged filters inside a generator can cause the functionality of the generator.

The overall condition of diesel fuel can easily be traced from the fuel tanks of a diesel-powered generator that should be focused on and certainly not ignored. Diesel fuel is an organic material that naturally degrades over time. You can not ignore this process, at some points water typically finds away in either during fuel delivery or concentration and that is what starts the bacterial growth.

To defend against the breakdown of diesel fuel over time is regular fuel evaluation and cleaning – also known as fuel polishing. Fuel polishing usually involves fuel testing, sampling, analysis plus sterilizing and cleaning particulates, fungi, bacteria, and rust out with the filters and chemicals and sometimes algae-based solutions, depending on the product.

Clean vs. Dirty Fuel

The point at which ‘good’ fuel turns into ‘bad’ is not always readily apparent. In other words, you can say, the transformation is a regular process that occurs over time. It is critical that a diesel generator’s fuel be regularly sampled, maintained, and tested to ensure its integrity. The quality of the fuel is directly associated with the reliability of the diesel generator.

How to spot contaminated diesel fuel?

If you have not had the diesel fuel in your diesel generator or fuel storage tank sampled, monitored, and analyzed. The following problems may occur either within the fuel tank or within the generator itself

  • The fuel will appear dark inside the tank.
  • The tank will emit an unusual smell.
  • At the bottom of the tank, Sediment will develop.
  • The generator engine will be dark in color while running at Exhaust.
  • The generator’s fuel lines or filters will appear clogged.
  • Starting system damage such as battery, relays, and electrical components.
  • The fuel injection pump and injectors will be damaged.
  • The generator output and engine performance may be interrupted.

How to Manage Diesel Fuel

Here are their main points to successfully manage your diesel fuel.

1. The Process for Outsource

Though this may be like a larger cost and a less-than-desirable option for some facilities. It also eliminates time restrictions and ensures a better outcome. An outsourcing company will handle every aspect of the process for you. It also supports a variety of workmanship.

This includes everything from diesel fuel sampling to controlling water, oxygen, and microbial risks. They can provide ongoing support for your system. The authenticity of these systems is what makes them so important for most organizations.

2. Using the Diesel Fuel Management System

  • This second option provides a balance between manual labor and outsourcing.
  • You can use a diesel fuel management system to automate much of the work for you on the basis of remote.
  • It works to check the fuel for you from time to time.
  • It can provide you with real-time updates on the quality of the fuel at any given time.
  • This is all managed via a web application.
  • If there’s any indication of a drop in fuel quality, the sensors pick this up and send an alert to you, allowing for a quick solution to be determined.
  • They can monitor water contamination, fuel levels, temperature change, theft of fuel, and much more.

3. DIY Route

These tips are for to do yourself, it is the in-house maintenance. See the tips below

  • Keep dry and clean the tank fill areas.
  • Don’t rely on automatic tank gauging devices to confirm the tank bottom water level.
  • Make sure you use a storage tank that meets the UL-142 standard. A tank meeting these criteria will go a long way to safeguarding diesel from the disease.
  • Ensure all tank openings have a strong seal to block contaminants from entering the tank.
  • Keep all storage tanks full to minimize the amount of oxygen and water condensation possible.
  • Keep systems as “water-free” as you can, with regular pumping to minimize as much as possible.
  • Check all the tanks have proper venting, but that vent covers themselves remain in good condition.
  • You need to test for microbial activity. If present, take steps to correct the problem.

Advantages of Cleaning Diesel Fuel and Fuel Polishing

When you run the standby generator with clean diesel fuel, the following advantages will occur

  • Lubricates and Cleans the injection system.
  • The chances to fail for Fuel injectors will decrease.
  • It helps in reducing the maintenance cost.
