steam calculation/advise

[fablab]

Possible to estimate how many BTU's it should take (I've only got about 25000) for a gas burner to generate enough steam to blow about 20 GPM water (flooded suction, almost zero lift) with one or two eductors/ejectors?

If so, what size pipe and jets should I order?

Thanks... I run machine tools better than "slide rules"

look at the penburthy website. They have a calculator that will allow you to determine the size of jet and the amount of steam you need to run it.
If you only have 25,000 BTU/hr then you might be better off with using water as the motive fluid or just a regular pump.
