FIELD: process engineering.
SUBSTANCE: invention relates to nuclear power engineering, particularly, to research and power reactors with liquid-metal lead-bearing heat carrier. Mass exchanger comprises housing with annular cover accommodating top grate arranged above heat carrier level and solid-phase oxidizer arranged above said top grate. Mass exchanger comprises also gas distributor arranged under solid-phase oxidiser, gas consumption booster and gas feed pipeline. One part of said pipeline communicates heat carrier chamber gas cavity while its other part communicated outlet of said booster with feed pipeline communicated with gas distributor. Note here that openings are made between annular cover and top grate, partly located above heat carrier level and partly in gas cavity.
EFFECT: friendly operation, efficient feed of oxygen.
