Diesel Generator Wet Stacking Phenomenon and Solution

Diesel Generator Wet Stacking Phenomenon and Solution

The diesel generator uses diesel fuel. When the power generator continues to run under no-load and light-load conditions for a period of time, the phenomenon of "Wet Stacking" will inevitably occur. This phenomenon is specifically: when the diesel generator is in a light load running state or the engine cannot reach the optimal operating temperature, those fuels that have not been fully burned are easily accumulated in the exhaust system of the diesel engine, and gradually It accumulates on exhaust pipes, fuel injectors, engine valves, and turbochargers, which greatly reduces the operating skills of diesel generators.

In simple terms, the so-called diesel generator wet stacking is the insufficient combustion of fuel and the carbon deposition of the engine caused by long-term light or no-load operation. If cleaning and maintenance are not performed in a timely manner, the use efficiency of the entire machine will drop dramatically. , Frequent start failures, excessive fuel, or the need to open the cylinder for maintenance too early may even cause the machine to be scrapped in advance.

In order to keep the diesel generator in a good running state, the specific operators should do more work on the fuel-air ratio and the operating temperature. Only in this way can the fuel be fully burned. From a practical point of view, it is generally difficult to achieve this condition with a load of less than 50%, so the diesel engine manufacturer should remind users to carry out on-load maintenance and related tests frequently. Through this activity, not only the "diesel generator wet stacking" problem can be solved, but also the performance of the fuel and electrical can be checked through the load test, so that the hidden dangers can be found and eliminated in time.
