Heating water with microwave

Hi,

How can I heating water with microwave?

I want to use it in industry?

any help is apperciated(ebook, paper, journal, catalog, website or simple text) :)

Take a look at your home magnetron and you hopefully understand.

You basically need the magnetron power supply, the waveguide and a dielectric window to the water volume. Unfortunately, the magnetron RF generation effiency is limited to about 70 % while a resitive electrical heater achieves 100%.
