Abstract:
1. A water recovery assembly for use in a molten carbonate fuel cell system having an anode and a cathode, said anode is adapted to receive fuel and to output anode exhaust, said water recovery assembly comprising: a first cooling assembly receiving and quench cooling said anode exhaust to recover a first portion of water including electrolyte from said anode exhaust and to output quenched electrolyte-free anode exhaust and electrolyte-containing water including said first portion of water, said first cooling assembly comprising: a quench assembly including a downward facing path passing said anode exhaust therethrough, and one or more spray water units injecting predetermined amount of spray water into the downward facing path for quench cooling said anode exhaust and condensing said first portion of water from said anode exhaust, and a recycling assembly comprising a blowdown assembly discharging a portion of the electrolyte-containing water outputted from said quench assembly to remove electrolyte and a recycle path recycling remaining water outputted from said quench assembly to said quench assembly for use as spray water; and a second cooling assembly comprising a packed tower which receives said quenched anode exhaust from the first cooling assembly and recovers a second portion of water from said quenched anode exhaust, said second portion of water being substantially free of electrolyte and suitable for humidifying said fuel supplied to said anode; wherein the water recovery assembly is part of the molten carbonate fuel cell system.
