Abstract
A condensing chamber and a heating chamber are arranged in an enclosure. Liquid is fed into the condensing chamber where it is pre-heated. The pre-heated liquid flows to the heating chamber where it is boiled to produce vapor. Gas sparging in the condensing chamber enhances heat transfer and absorbs additional vapor generated by pre-heating. The condenser is a helical or other horizontal tube heat exchanger.
