Heating of water in continuous-flow porcelain tube - using induction heating of coaxial inner metallic tube by microwave emission from coil surrounding outer porcelain cover

摘要

The method of heating water involves enclosing a porcelain tube on both sides and at its ends by porcelain covers stayed by a concentric metallic tube with external threads. Cold water entering at one end of the metallic tube flows through radial holes into the interior of the porcelain tube, where it becomes heated by microwaves absorbed into the metal. At the opposite end, hot water returns through more radial holes into the metallic inner tube and is drawn off. USE/ADVANTAGE - For industrial and domestic hot water supplies, easily mfd. appts. occupies little space and consumes less power for the same heating effect.
