Thanks Etex, you've brought home an obvious point to me:
If I want water at 43C then we know the oil must be at least this temperature (actually it will be more - some thermal gradient is needed) when it leaves my heat exchange.
So I must consider how well my hydraulic circuit will behave at...
Those are fair comments thankyou yvesLLwelyn. The engine won't give me 10kW at idle. I was wrong to suggest alternator inappropriate because engine would be idling when it was used.
But then I must consider also, as soon as whatever "top up" heat generator kicks in because of lack of load on...
I like the diesel fired water heater, but doubt I need it. I'm stingy on weight and capital and maintenance.
The thing is, I need a hydraulic powerpack regardless of water heating requirements. It will have a dedicated marine diesel of about 40kW. I'll get a good start on my heating...
Thanks Brian,
But I wondering why web searches of "mechanical water heater" and "hydraulic water heater" etc aren't showing me where others have done this.
Maybe they do it but don't bother publish! Or maybe people seldom have plenty of hydraulic power while little or no electric power (at same...
The water I'm heating is a constant flow to go through a diver's wetsuit. A situation where the water wouldn't be heated enough by the jacket and exhaust of the diesel engine would arise where engine wasn't working hard. I'm guessing I might want 10kW of heat going into a stream of 10 l/m.
I'd...
Can I heat water mechanically using something like a torque converter?
I have a diesel motor powering a hydraulic pump for various work. I also want a supply of hot water. I will take what heat I can from the diesel motor's water jacket and exhaust, but if my water still isn't quite to desired...
