FIELD: non-ferrous metallurgy. ^ SUBSTANCE: furnace comprises steel casing, lined gas chamber, and gas distributing grate mounted on the load-bearing beam and connected with the casing by means of a sheet compensator. The grate has inner compensator made of arc-shaped plate welded to the casing and grate. The space of the inner compensator is filled with the asbestos fibers, and the space between the sheet compensator and inner compensator receives air under pressure supplied through the branch pipe with a flow rate of 1-2% of the flow rate of air supplied to the gas chamber of the furnace. ^ EFFECT: enhanced efficiency and prolonged service life. ^ 2 cl, 1 dwg |
