Is this even possible? (heat exchanger problem)
Is this even possible? (heat exchanger problem)
(OP)
I am currently dealing with a problem involving the heat transfer between two gases. Would it be possible to take JP-8 Fuel Exhaust (990C) and heat up water (starting at 140C, 9.8MPa) to produce 900 KW? The flow-rate of the water is 0.9kg/sec.
There is an extreme size-restriction on this heat exchanger, which is limited to 1.5m x 0.6m x 0.6m.
I read through this "Guide to Compact Heat Exchangers" (link below), and found that the Module 2.5 was the closest to the one I am trying to design, however the size-constraints and input-ranges specified are not within my range of desired inputs.
Thanks for all your help.

If this is waste heat recovery from e.g. a gas turbine then these uints are sold as packaged units typically though the gas turbine vendor.

I am still curious ... Who are the leading Heat Exchanger makers for Mack Trucks, and other heavy trucks? Do those heavy trucks have this type of similar concept, using exhaust gas to heat up fluid?
The exhaust gas mass flow rate is about 9lbs/second. The allowed volume has almost doubled to about 10' x 2' x 1.5'
Thanks again,
Eugene

Curiosity is an important thing for engineering, but I cannot imagine a heat recovery system installed on a truck, for intermittent operation, operating at aroung 1420 psi, to recover 900 kW from the 300-400 kW Mack engine. Obviously, I'm missing something. Besides a cabin heater and a few coolers for engine coolant, oil, power steering oil and the like, I don't know other heat exchangers installed on a truck, however why would you generate high pressure steam on a mobile plant and how you use it? And how you keep the steam hot, when you stop for refueling or for a quick toilet run?
