RE: Air Heater

It looks like English is not your first language, pimeng12. Perhaps you could upload a sketch with labels to us, so we can see what you mean?

Pick up that 2000 lb phone and call some suppliers!!??

RE: Air Heater

If you are trying to say air handler with heating coil (using hot water or steam), then a shell and tube heat exchanger is not used. The heating "element" looks very similar to a car's radiator.

Dear All.
Thanks for your responses.
Yes right English is not my first language so I'm very sorry about this inconvenience.
for the above case i mean there are 1 row tube for steam and 4 row tubes for hot water, both in one shell that air passed. Is this air heater can be classified as shell & tube Exchanger. Here i attached the sketch.

Thanks you.

RE: Air Heater

Actually, your English in the last post was impeccable. Thanks for the sketch.

A shell & tube Hx has a shell that completely encases the tubes, usually with a pressure rating that governs the shell thickness. The type of Hx that you have shown isn't usually thought of as a S&T type of Hx.

RE: Air Heater

I'd be interested in seeing some details on the internals before I say yes or no. Heating air and water streams with a steam source in one device isn't something I've seen before and I wonder what the internals would look like.

RE: Air Heater

Definately not a S&T.
