  • COMPACT TOTAL EVAPORATOR AND DEVICE FOR CARRYING OUT THE CONTROLLED MIXING, EVAPORATING AND/OR REACTION OF A NUMBER OF FLUIDS
    Publication number: 20140231027
    Abstract: A total evaporator for fluids, including a cold chamber to prevent pre-evaporation, an evaporation region connected thereto having narrow flow cross-section for fast evaporation of the fluid, and a subsequent vapor chamber for pulsation damping and the controlled superheating of the vapor, the evaporation region being formed by a gap between concentrically nested cylindrical and/or conical tube sections and heat required for the evaporation and superheating processes is supplied by electric heating and/or by hot fluid and/or by catalytic or homogeneous combustion via the wall of the concentric tubes.
    Type: Application
    Filed: February 18, 2013
