steam superheater

[eli73]

Anyone have experience specifying a superheater to supply steam to a process evaporator? Specifically, this plant runs their main boilers at 150 psig to meet the sporadic (2-4 times per hour for a few minutes) demand of the evaporator. Would like to run lower pressure and use dedicated equipment that can respond to need. Can a localized superheater fill that requirement. Any recommended suppliers with experience?

Thanks

Why do you want superheat when using it for an evaporator?

You don't want superheated steam in a heat exchanger. Superheat is sensible heat, and you'll have to use THAT up before you get to where the real action is - the latent heat given up when the saturated steam condenses. With superheated steam, your heat exchanger will behave very much like it's airbound.

What's the temperature level you need in the evaporator ? What H/E surface is available to evaporate ?
