ABSTRACT:
In apparatus to convert cryogenic fluid to gas, a vaporizer having passages to pass the cool or cold cryogenic fluid in heat transfer relation with warming gas flowing downwardly through the vaporizer, structure extending below the level of the vaporizer to receive the downwardly flowing gas and to re-direct it to discharge to atmosphere, the structure including ducting configured and sized to enhance the down flow and discharge rates of the gas, whereby the temperature of the discharged gas is maintained above the level that would exist in the absence of the ducting, and potential fogging at the discharge is reduced.
