A low-smoke carbon furnace including an outer casing, a removable liner, and an annular interlayer is provided. The removable liner is disposed in the outer casing. The removable liner is provided with a combustion chamber therewithin. The removable liner includes multiple secondary air inlets disposed on an upper side wall of the removable liner. The annular interlayer is disposed between the outer casing and the removable liner. A bottom end of the outer casing is provided with interlayer air inlets that communicate with the annular interlayer. Oxygen enters the annular interlayer via the interlayer air inlets, and thereafter enters the combustion chamber of the removable liner via the secondary air inlets to facilitate secondary combustion in the combustion chamber.
