Storing diesel fuel properly is crucial for the efficient and safe operation of portable diesel generators. As a supplier of portable diesel generators, I’ve encountered numerous customers with questions about diesel fuel storage. In this blog, I’ll share some essential guidelines on how to store diesel fuel for your portable diesel generator effectively. Portable Diesel Generator
Understanding Diesel Fuel Characteristics
Before delving into storage methods, it’s important to understand the basic characteristics of diesel fuel. Diesel fuel is a hydrocarbon-based fuel derived from crude oil. It has a relatively high energy density, which makes it an ideal choice for powering generators. However, diesel fuel is also prone to oxidation and contamination over time.
Oxidation occurs when diesel fuel reacts with oxygen in the air, leading to the formation of gums and sediments. These by – products can clog fuel filters, injectors, and other components in your generator, reducing its performance and potentially causing breakdowns. Contamination can come from various sources, such as water, dirt, and microorganisms. Water can cause corrosion in the fuel system, while dirt and microorganisms can also lead to blockages.
Choosing the Right Storage Container
The first step in storing diesel fuel is selecting an appropriate storage container. The container should be made of a material that is resistant to corrosion and leaks. Here are some common options:
Metal Containers
Metal containers, such as steel drums, are a popular choice for diesel fuel storage. They are durable and can withstand rough handling. However, metal containers are prone to rusting, especially if they come into contact with water. To prevent rusting, make sure the container is coated with a corrosion – resistant paint or liner. It’s also a good idea to store metal containers on a wooden or plastic pallet to keep them off the ground and away from moisture.
Plastic Containers
Plastic containers are lightweight, easy to handle, and resistant to corrosion. Look for plastic containers specifically designed for diesel fuel storage. These containers are usually made of high – density polyethylene (HDPE) and are designed to meet safety standards. They come in various sizes, from small Jerry cans to large storage tanks. Make sure the plastic container has a tight – fitting lid to prevent spills and evaporation.
Storage Tanks
For larger quantities of diesel fuel, storage tanks are a more practical option. Stationary storage tanks can be installed above – ground or underground. Above – ground tanks are easier to install and maintain, while underground tanks are more aesthetically pleasing and may be required in some areas for safety or regulatory reasons. When choosing a storage tank, make sure it is certified for diesel fuel storage and meets all local codes and regulations.
Preparing the Storage Area
Once you’ve chosen the storage container, you need to prepare a suitable storage area. The storage area should be well – ventilated to prevent the buildup of flammable vapors. Here are some key considerations:
Location
Choose a location that is away from sources of heat, sparks, and open flames. This includes heaters, electrical equipment, and smoking areas. The storage area should also be away from high – traffic areas to reduce the risk of accidental damage to the storage container. If possible, store the fuel in a separate, well – ventilated building or shed.
Temperature and Humidity
Diesel fuel storage is best at a stable temperature. Extreme temperatures can affect the quality of the fuel. High temperatures can accelerate oxidation, while low temperatures can cause waxing, where the diesel fuel thickens and becomes less flowable. Aim to store diesel fuel at a temperature between 40°F and 80°F (4°C and 27°C). Additionally, keep the storage area dry to prevent water from condensing inside the container.
Level Surface
Place the storage container on a level surface to prevent spills and ensure proper fuel flow. If you’re using a storage tank, make sure it is installed on a sturdy foundation that can support its weight when full.
Filling and Sealing the Storage Container
When filling the storage container, take the following precautions:
Use a Proper Funnel
To prevent spills, use a funnel specifically designed for diesel fuel. Make sure the funnel is clean and free of debris.
Fill Slowly
Fill the container slowly to avoid splashing and foaming. Foaming can lead to inaccurate measurements and may cause diesel fuel to overflow.
Seal Tightly
Once the container is filled, seal it tightly to prevent air and moisture from entering. Check the container regularly for any signs of leaks.
Fuel Treatment and Additives
To extend the shelf life of diesel fuel and prevent problems such as oxidation and microbial growth, consider using fuel additives.
Oxidation Inhibitors
Oxidation inhibitors slow down the oxidation process, keeping the fuel fresh for a longer period. They are particularly useful if you plan to store diesel fuel for an extended time.
Water Separators
Water separators help remove water from the fuel. Since water can cause corrosion and microbial growth, reducing the water content in the fuel is essential for maintaining its quality.
Microbial Biocides
Microbial biocides kill bacteria and fungi that can grow in diesel fuel, especially in the presence of water. These additives can prevent the formation of biofilms that can clog filters and fuel lines.
Regular Monitoring and Maintenance
Regular monitoring and maintenance are essential to ensure the quality of the stored diesel fuel.
Visual Inspections
Periodically inspect the storage container for signs of damage, leaks, or corrosion. Check the fuel level to ensure there are no unexpected drops, which could indicate a leak.
Fuel Sampling
Take fuel samples at regular intervals and test them for quality. You can check for the presence of water, sediment, and changes in the fuel’s chemical properties. If the fuel quality deteriorates, it may be necessary to replace or treat the fuel.
Filter Replacement
If your generator has a fuel filter, replace it regularly according to the manufacturer’s recommendations. A clean fuel filter helps prevent contaminants from entering the engine and ensures smooth operation.
Using the Stored Diesel Fuel
When it’s time to use the stored diesel fuel in your portable diesel generator, follow these steps:
Check the Fuel Quality
Before adding the fuel to the generator, visually inspect it for any signs of contamination. If the fuel appears cloudy or has sediment, it may need to be filtered or replaced.
Fill the Generator’s Fuel Tank
Use a clean funnel to transfer the diesel fuel from the storage container to the generator’s fuel tank. Make sure not to overfill the tank.
Prime the Fuel System
If your generator requires priming, follow the manufacturer’s instructions to prime the fuel system. This helps ensure that fuel flows properly to the engine.
In conclusion, proper diesel fuel storage is essential for the reliable operation of portable diesel generators. By understanding the characteristics of diesel fuel, choosing the right storage container, preparing a suitable storage area, using fuel additives, and conducting regular monitoring and maintenance, you can ensure that your stored diesel fuel remains in good condition and your generator operates efficiently.
