Problems solved by technology

The flame spreads along the burner installation direction above the hearth made of refractory materials, and the high-temperature flue gas is discharged directly from above. Only by radiation heat transfer to heat the hearth, the temperature rise is too slow to meet the heating requirements, and the efficiency is low. The waste is serious; and when the flame length is large, it is directly sprayed to the side wall of the opposite water jacket, and there is a risk of damaging the side-blown furnace

Abstract

The invention discloses a side blown furnace which comprises a water jacket, a furnace body, a hearth and a baking furnace burner, wherein the cross section of the furnace body is rectangular; the hearth is formed by piling a refractory material; a furnace bottom takes the shape of an inverted arch; the furnace body at the upper part of the hearth is formed by the water jacket in a surrounding manner; a heating opening is formed in the water jacket; the baking furnace burner comprises a first air inlet pipeline and a second air pipeline; the second air pipeline is positioned in the first air pipeline; the baking furnace burner penetrates through the heating opening of the water jacket to enter the upper part of the hearth. The side blown furnace provided by the invention has the advantages of being simple in structure, convenient to use, high in utilization ratio of energy sources and good in baking effect.

Description

Technical field [0001] The invention relates to a non-ferrous metal smelting combustion equipment, which belongs to the field of chemical smelting, in particular to a side blowing furnace. Background technique [0002] With its unique structure, the side-blowing furnace can only install the burner on the side wall of the water jacket above the hearth of the side-blowing furnace. At present, the burner nozzles for side-blowing furnaces all adopt the direct-injection flame type, that is, the flame propagation direction is the burner installation direction. The flame spreads over the refractory masonry hearth along the installation direction of the burner. High-temperature flue gas is directly discharged from above. Only radiation heat is used to heat the hearth. The temperature rise is too slow or even unable to meet the heating requirements, and the efficiency is low. The waste is serious; and when the flame length is large, it is directly sprayed to the side wall of the opposite...
