CAPILLARY FEED BOILER

摘要

A liquid boiler (10) generates vapor at low pressure from liquid in reservoirs that are not pressurized. Liquid from a reservoir (150) is fed through a supply wick (40) by capillary action to a boiler wick (20) in which the liquid is heated and boiled to a vapor. The heat for vaporization is transmitted by a porous hot seat (30) which sits atop and is in contact with the boiler wick (20). The boiler wick (20) and hot seat (30) are contained in an insulating cylindrical shroud (19), which forms a tight seal with the edges of the boiler wick (20). If the liquid to be vaporized is a fuel for a burner, then combustion heat can be used to supply the heat to the boiler. A resistive heat can also be used to heat the hot seat and boiler wick.
