Wet Stacking in diesel generators and how to eliminate it?

It’s important to safeguard the commercial well-being with an industrial generator that’s ready to meet the organization’s needs. When left unattended for lengthy periods of time, backup diesel generator can be subject to a detrimental process called wet stacking. Firstly, it is essential to understand what is wet stacking. Wet stacking is a condition that occurs when the unused diesel fuel, accumulated moisture, and carbon particles are allowed to gather in the exhaust of the diesel generator. This can happen for a number of reasons but usually results from diesel fuel not being properly burned off during use. As a result, a dark muddy liquid congeals in the generator’s exhaust stacks — hence the term "wet stacking".

Wet stacking can occur as a result of several issues. However, the primary reasons are:

• Letting the generator sit unused for long periods of time
• Not allowing the generator to run under its designated operating temperature
• Allowing the generator to run at less than 60% of its rated output
• Running the generator with an incorrect air-to-fuel ratio
• Having too little fuel in the generator

Wet stacking is hazardous to genset injectors, exhaust valves, and other functional features. And, when left untreated, wet stacking can inhibit the performance of diesel genset as well as significantly reduce the lifespan of the unit.

Here are some tips to fix the problem of wet stacking in the generator:

Avoid it entirely

It’s worth mentioning that wet stacking is avoidable by following two simple rules: run the generator for a few minutes once a week, and make sure a qualified technician services the DG genset at regular intervals.

Run genset for a bit

If wet stacking is observed within the unit early enough, one can fix it by running the generator at its properly designated operating temperature.
