Abstract
Official abstract text for this publication.
An intelligent electronic device (IED) may monitor wet stack residue buildup of a diesel engine. Once the wet stack residue accumulates to a certain amount, the IED may perform a mitigation procedure. Additionally, tracking wet stack residue buildup may allow an IED to attempt to prevent or reduce accumulation of the wet stack residue. The IED may track an operating power level of the diesel engine to estimate the rate of residue buildup.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method to mitigate wet stack residue, the method comprising: monitoring a plurality of diesel engines for residue buildup; identifying a diesel engine from the plurality of diesel engines with an amount of residue that exceeds a residue threshold; altering a power output of the diesel engine or a load associated with the diesel engine to increase an operating power level of the diesel engine; estimating that residue of the diesel engine has been reduced below the residue threshold based on an amount of time at an increased operating power level; and reducing the power output of the diesel engine or the load associated with the diesel engine to lower the operating power level. 2. The method of claim 1 , further comprising altering the load associated with the diesel engine, wherein altering the load comprises placing a second diesel engine in parallel with the diesel engine, and operating the second diesel engine at zero fuel. 3. The method of claim 1 , further comprising establishing a dispatch program that periodically sets one or more diesel engines of the plurality of diesel engines to a high operating power level to mitigate wet stack residue accumulation. 4. The method of claim 1 , wherein altering the power output or the load comprises changing dispatch instructions to the plurality of diesel engines to cause the diesel engine to increase the operating power level.
