Guess this is as good a thread to post this as its a HD diesel issue.
My town has a 350 KW genset powered by a Deere 13 or 14 liter engine. It is on our joint fire/police station and is probably8-10 years old (building was new then)
Mind you the facility is that old and all of a sudden we are going to spend $57,000 to ad a "Diesel Particulate Filter". Seems like all of a sudden the "air quality" in the building is poor when the unit goes into its test cycle every Tuesday at around 10AM as the exhaust on the genset is only about 8' off the ground about 5' from the building and the exhaust fumes make it to the HVAC air intakes on roofs.
As a taxpayer I went down there to look t it and got a quick tour. I asked.."why not put a stack on it"? Answer.."$100,000". I then said..."Move it 70' to edge of parking lot"...that too.."$100,000.
So I send email to town Administrator with cc's to Selectmen and basically say a DPF will only service to have a negative effect on motor performance and the employees will in any case still be saying..."what's that smell?" To say nothing of adding to maintenance cost associated with the DPF not functioning.
I have asked to see the cost estimates that support the 100G alternative figures and of course get nothing. My guess is a double wall stainless thin wall pipe as you would use for a large wood/coal stove could be added for 5-10g. Or a schedule 40 8' pipe for about the same-to a 35' height. As for relocating the unit, you would saw cut asphalt (18" width, excavate trench to say 3ft. throw new feed from unit to existing distribution panel on building as well as a couple of control wires. As for physical move, it's a typical skid. One large hydraulic crane parked at 35' line and its a 15 minute pick of 180 degrees. And as it's a skid, no need for anything but a floating slab to set it on. I've also suggested changing the test cycle to say 6 or 7 PM on a Sat night. Worst case 2 cops on duty. (After building this new structure with a very nice "dispatch" room, we join a regional dispatch operation and a big savings) Even during week, max occupancy is 3 in PD and 2 on Fire side. No cost for that. Granted that does nothing for "extended use" air quality issues (about 8 or so years ago we were without power for almost a week because of one **** of an early ice storm when trees were still loaded with leaves)
I talked to an Deere engine sales guy (Marine/gensets) and he concurred- Unless the spent about 30 g to modify engine to handle a regeneration cycle-can't believe a Deere "crate motor" would cost that much- you will have to manually clean the DPF trap on a regular basis.
Any opinions. I liken this to having a "hot" 327 Chevy or Ford 289 Hi-Po from the 60's and saying.."want to make this baby run? You need state of the art emission controls"
