ABSTRACT:
A vaporizer for generating a process gas from a gas-liquid mixture fluid includes a container defining a process space of the vaporizer. A supply head having a plurality of spray holes to spray the fluid is disposed within the container. A heating passage is disposed below the spray holes within the container. The heating passage is configured to heat the fluid passing therethrough and thereby generate the process gas. A gas delivery passage is connected to the container to laterally deliver the process gas from below the heating passage. A mist receiver is provided at the container below the gas delivery passage.
