The Key to Efficient Operation the Diesel Generators

No one is willing to frequently replace diesel generators, which is important because it will help extend the service life of the generator set so that it can work normally at all times.

Improper operation of a diesel generator is different from running an expired oil changed car. Although it is possible to exceed the recommended distance before changing oil, running a diesel generator without keeping up with maintenance or "light load" operation will inevitably shorten the lifespan of the generator set.

If maintenance and loading are not carried out properly, diesel generators may lead to unplanned shutdowns, extended maintenance time scheduled for the "life cycle", and increased operating costs due to excessive fuel consumption leading to excessive wear and emissions.

What does the efficiency of diesel generators mean?

Regardless of the method used, all generator sets, whether diesel or natural gas, are designed to provide electricity in the most efficient way possible. In this way, each unit will have an optimal contact point between workload and diesel consumption. Because different engines use different diesel consumption rates, and higher workloads almost always result in the best combustion of fuel, the efficiency of diesel generators usually reaches a higher level within the load guaranteed by the generator set design. For example, the diesel consumption of a 150 kW diesel generator is lower than 60 kW, indicating a lower diesel consumption.

One of the most common problems with diesel generators operating below their designed load capacity for a long time is the phenomenon of "wet accumulation" in the diesel engine. When the operating temperature is low, a wet stack will be generated when the unburned fuel is depleted. After unburned fuel is discharged from the combustion chamber, it will accumulate at the engine exhaust end, causing fuel injector fouling, carbon buildup on exhaust valves, turbochargers, and exhaust pipes.

In order to avoid wet stacking and other problems caused by the light load operation of the generator set, it is necessary to achieve the best operating state of the generator set as much as possible. Here are some widely accepted best practices for diesel generator efficiency.

Generator set load setting.

Backup and regular diesel generators - These generator sets are typically optimized at a total load of 50-80%.

Continuous rated diesel generators - These types of units are typically optimized to operate at 70-100% of the total load.

The long-term low load operation of diesel power generation opportunities has a significant impact on the health of equipment. This situation can lead to unplanned shutdowns, increased maintenance costs, improved fuel efficiency, and reduced comprehensive usage time of the generator set. The efficiency of diesel generators is crucial because of their optimal load-bearing capacity. Of course, scheduling regular generator maintenance will help you ensure the longevity of your equipment.
