The invention discloses a low furnace chamber energy-saving sintering ignition furnace and belongs to the field of a sintering ignition furnace. The sintering ignition furnace comprises a sintering ignition furnace body, L-shaped furnace door beams and a burner nozzle beam. The L-shaped furnace door beams are arranged at the two side edges of a furnace chamber of the sintering ignition furnace body respectively; the burner nozzle beam is arranged on the top portion of the furnace chamber; the length of the L-shaped furnace door beam is larger than that of the burner nozzle beam; the L-shaped furnace door beam and the top portion of the burner nozzle beam are arranged in the same horizontal plane; and the height between the bottom portion of the burner nozzle beam and the top portion of a trolley is 250-350 mm. The furnace chamber of the low furnace chamber energy-saving sintering ignition furnace is lower than a furnace chamber of a conventional sintering ignition furnace; and after the furnace chamber is lowered, the height between a burner nozzle and the trolley is reduced, so that flame between the burner nozzle and the trolley is short, heat value is high, and sintering efficiency is improved.
