A
biomass fuel aluminum
melting furnace comprises a furnace body (1), a
crucible (2), an air inlet (3) and a feeding
pipe (4). A cavity is arranged in the furnace body (1) and is formed by separating the furnace body (1) through a
refractory brick layer (5). A
smoke channel (1.3) and a gas
inlet channel (1.4) are arranged in the space between the
refractory brick layer (5) and the inner wall of the furnace body (1) and is formed by separating the furnace body (1) through a heat-conducting material layer (13), wherein the inlet and the outlet of the
smoke channel (1.3) are located at the two ends of a C-shaped structure respectively, the inlet and the outlet of the gas
inlet channel (1.4) are also located at the two ends of the C-shaped structure respectively, the inlet of the gas
inlet channel (1.4) is communicated with the air inlet (3), and the outlet of the gas inlet channel (1.4) is communicated with an ash chamber (1.2). One end of the feeding
pipe (4) is located in a
combustion chamber (1.1), and the other end of the feeding
pipe (4) is located outside the furnace body (1). Compared with the prior art, the
biomass fuel aluminum
melting furnace has the
advantage that the
crucible is capable of being evenly heated, long in service life, high in heat exchange efficiency, low in
energy consumption, good in use stability and low in aluminum melting production cost.
