FIELD: sprayers for introduction of oxygen into fluidized-bed reactors.
SUBSTANCE: proposed sprayer has oxygen supply pipe and nozzle connected with pipe and used for delivery of oxygen through pipe outside. Nozzle is provided with casing and insulation surrounding the pipe and casing over entire length of casing; pipe and casing are surrounded with envelopes. Space between pipe and its envelope and space between casing and its envelope is filled with insulating material. Envelope of casing terminates at side member which partially closes outer end of circular space between casing and its envelope.
EFFECT: enhanced resistance to high temperatures.
