Firetube two pass heat exchangers pressure drop

[samshreve]

Looking for pressure drop readings for exhaust side of two pass firetube heat exhangers in an engine driven waste heat recovery application. Are there any of these type units around Oklahoma, or Texas? Please call 318-686-4709 if you know of these units locations or post them here. I would also want to know engine exhaust flow, incoming gas temperature and outgoing gas temperature as well as the other side process weather making hot water or steam. Need water flow and in and out temperatures, or in steam applications, steam pressure being made and feedwater temperature in. Also need to know number and size of tubes/pass. Type fuel being used in engine is helpful, also.

What type of systems?

Caterpillar used to provide good info on this for their genset/WHR applications. May be worth calling them.

Well, I am looking for units that are supplied to CAT. Type of units, are firetube waste heat recovery silencers, such as Vaporphase makes or Maxim. I don't believe the pressure drop numbers that I get from Maxim's program and I want to test some units in the field with a manometer or if I get lucky some by perhaps, by reading pressure transmitters before and after the Waste Heat silencer.

Have you talked to anybody at Beaird Industries right there in Shreveport?? They make heat recovery units for engines and turbines.

I worked with Maxim for six years. I think their pressure drops are to low. By the way, they just moved from Shreveport to Houston. Now they are just Maxim silencers, and not part of Beaird Industries anymore. I currently work for a competitor, so I think talking to them will not be any help.

I found it hard to believe that you were in Shreveport and conversant as you were in the process, and had not heard of Maxim (Beaird).

Did the evaporator group move to houston as well??

The evaporator group stayed with Beaird Industries.
Did you do much work with them? Do you work with engine heat recovery?

I worked in the evap. group as a project eng'r under DR. Fred G., but that was many lifetimes ago.

I do currently work with heat recovery, but it is rarely applied on recips. More often with turbines, boilers and combustion related processes.
