SIDE-SUBMERGED COMBUSTION SMELTING APPARATUS FOR SPRAYING OXYGEN-ENRICHED AIR AND PULVERIZED COAL

摘要

A side-submerged combustion smelting apparatus (1) for spraying oxygen-enriched air and pulverized coal includes: a smelting furnace (100); a pulverized coal delivery pipe (200) for delivering the pulverized coal; an air delivery pipe (300) for delivering the oxygen-enriched air; a plurality of coal injection assemblies (400) arranged at intervals on two opposite side walls of the smelting furnace (100), each coal injection assembly (400) including a pulverized coal lance (410) and an air lance (420) that are adjacent to each other and arranged as a pair, and each coal injection assembly (400) at least partially extending into the smelting furnace (100).
