International ClassesF22B 001/28H05B 001/00 F24H 001/10 AbstractAn improved vaporization system includes an automated valve and positive displacement pumping system using a pair of pumps operating in opposition to one another to provide continuous and constant volumetric flow at a constant predetermined pressure to an improved vaporizer using a stack of heated disks to flash vaporize the liquid. The valves are improved by providing one way flow.Field of SearchVaporizerMethod Liquid evaporant (e.g., water, etc.) In continuous flow line connected heater Pipe or tube forms flow path With internal heating element In-line connected closed tank (i.e., pressurized) With internal heating element In-line connected open tank or container (i.e., nonpressurized) Flash chamber Heated line section with heating element internal of flow path FLASHER Fluid fuel | |
