They play the water injection game on the gas turbines too (LM2500 and frame 5)....evil nox, go away LOL. I'm chasing a small nox problem with 6 4.4mW CAT's (I forgot model number). I'm gathering data and interviewing now LOL. I'm still young and an engineer...two things that can get one in trouble around plants. But when I show operators/mechanics my dirty fingernails, they usually open up! Unless you tell them how would anyone know your as young as you are? If I didn't know your age I'd guess about 50 from looking at you. Brian

50? Damn, did I accidentally post my ass instead of my face somewhere?
Oh, cat's are 3616's. Anybody have experience with these? CAT says 20,000 hour between top end overhauls. Any reason we can't go longer if compressions, oil analysis, and all other variables are good?

At least we solved that pesky nox problem. Personally I think that's the reason everybody's so unhappy these days. Less laughing gas in the air. As far as old folks you're right, they were always cool as soon as they figured out that I knew what I was doing and didn't have an attitude about it.

Retarding the timing was one idea I had too. First I needa get some info on intake air...there are 6 of these things next to each other in a building with not so great ventalation. The engines suck air in right on their skid with no ductwork to the outside. Who knows when the aftercoolers were cleaned (water and air side). The turbos got approved to be overhauled---they could be leaking oil.
All units were running yesterday at about the same load and each one had much different readings on the engine gauges. One had 130deg water temp, the other 190. One had 210 intake air temp, the other 140. Can't analyze data if it's crap!
I could just do water injection after the turbo LOL.
I guess retarding the timing 0.5 degree and seeing what that does would be worth a shot. I'm slowly getting them to do the crap I want, like compression tests, etc.

6/19 - Canada Steamship Lines (CSL) has signed a Letter of Intent with Singapore-headquartered Ecospec Marine Technology covering installation of Ecospec's CSNOx gas scrubbing technology on one of CSL's Great Lakes' vessel later this year.
In the CSNOx system, the pH value and alkalinity of scrub water is corrected prior to scrubbing using an ultra-low frequency electrolysis system (ULFELS). Seawater goes through an additional antifouling pretreatment to control microbial growth in the system. The alkaline water is then pumped through the exhaust stack to scrub the flue gas. Ecospec says that CSNOx treated water is highly reactive and effective in removing CO2, SO2 and NOx through absorption and that the removed pollutants are converted into the harmless substances found naturally in water. After scrubbing, the scrubbed water may pass through a solid-liquid separator to remove solid particles. The recovered water will then undergo an integrated treatment to meet the discharge water standard. If the water supply is limited, the scrubbed water can be further treated and recycled back to the scrubbing process, reducing the amount used.
The CSL CSNOx installation will be the world's first on a vessel operating in a fresh water environment. The vessel was not named.
Ecospec claims that CSNOx is the world's first commercially viable solution that can effectively reduce SO2, NOX and CO2 emissions from large ocean trading vessels with all three gases being removed in one process and in a single system, without using harmful chemicals.
More importantly, CSNOx is claimed to be the only marine exhaust gas abatement process capable of offsetting and net reduction in CO2 emission trails. This is contrast to conventional scrubbers that increase CO2 emissions as a result of chemical reactions in the scrubbing process, or because they may not have the capability to offset CO2 emissions by the additional energy used.

Nothing like saving the day by finding an old PLC output board on ebay for $40!

You are lucky that they agreed to ship it out of the country. When we sell on ebay it is to the states only. Made that mistake once...never again!!! ppat

I'm not out of the country. Shipping is via US Post Office Priority Mail. I have a zip code 96915 and state: GU.

I understand...but it is not one of the Continental states...ppat
