Avoiding Standby Diesel Full Load testing by use of CbM

Avoiding Standby Diesel Full Load testing by use of CbM

Avoiding Standby Diesel Full Load testing by use of CbM

(OP)
There are many assumptions with my question so please correct me on any. We have a dozen of old and new standby power gererators in our infrastructure facilties. Monthly plant load tests are done for ~ 1/2 hr to 1 hr. Most of these diesel engines see from 10 - 25% load. Full load tests are recommended annually for generators not able to operate above 30% rating or lower than manf. recommended operating exhaust gas temps (NFPA 110/CAT/Cummins). These are all great for minimizing and removing wet-stacking and carbon build-up. If preventing wet-stack is the most important benefit for operating diesels at their high op parameters (Full-loading) is there a more direct method for observing and monitoring buildup in the combustion and exhaust chambers? Can a visual or boroscopic observation be performed with minimal intrusion and cost? NDT methods available?

RE: Avoiding Standby Diesel Full Load testing by use of CbM

If you are operating at 10-25% load you most likely have accumulation and/or buildup and the run up to 70% to 80% load until the stack is clear is the best way to remove it; no special tools, no disassembly, etc.
