Listeroid Engines / Listeroid WVO Co-Generator - Can the Listeroid take the heat?
« on: November 17, 2007, 03:09:37 AM »
Thanks for the advice on disassembling my 12/2 from my previous thread. I will heed it. Here is another question. What is the ideal operating temperature of a 12/2?
The real reason I am moving the ‘roid into the basement of the garage is to plumb the engine into the central hydronic heating system on my property. I plan on both using the heating system, powered by free, waste dead wood, to constantly heat the Listeroid, as well as to use the waste heat from the engine when it is running, to heat the house, apartment, hot tub and pool. I do not know yet what the duty cycle will be of the engine and generator, but I assume it will be no more than 8 hours running and 16 hours at rest a day.
I had always intended to do some type of ”co-gen” system with the Listeroid, that is, use the waste heat as well as the electricity from the gen set, but now that I moved to a large property with a few buildings, now all connected with highly insulated, underground thermal PEX, all the pieces are coming together for my dastardly plan.
My question is this: What is the ideal temperature to run a 12/2? Can anyone give me a good reason why I should not run hot water through the engine at all times regardless of the engine running or not? The water will be between 174 and 186 degrees and the flow will probably be about 6 or 8 gallons a minute. The fluid I am using is essentially 400 gallons of tap water, with a small amount of corrosion inhibitor, and is corrected for a neutral Ph level. There is no antifreeze in it at all, but provisions are made to prevent it from freezing as well as overheating (boiling)
My little scheme seems to be like a win-win. Use the waste wood (and waste vegetable oil) furnace to heat the engine (and waste vegetable oil fuel for running the Lister) to operating temperature 24/7, while at the same time, when the engine is running, harness that waste heat to reduce the burden on the furnace, offering perhaps 40K btu of free heat – all without having to build a radiator for the ‘roid or expose the engine to cold motor oil or warm up times.
Does anyone know if I am missing a real showstopper of a blunder? I would love your comments!
Thanks again!
