PARTIAL REDUCTION FURNACE

摘要

A partial reduction furnace (100) is provided with: a lattice-like grate (111) that can travel along a horizontal direction; a windbox (112) arranged so as to cover the lower portion of the grate (111); and a feed nozzle (113) and feed blower (114) connected to the windbox (112) and for feeding combustion gas to the interior of the windbox (112). The partial reduction furnace (100) is provided with louvers (116A, 116B) installed on the windbox (112) along a horizontal direction so as to separate the grate (111) and the feed nozzle (113), and causing a drop in pressure in the combustion gas (1) from the feed nozzle (113).
