The invention discloses a low-NOx clean combustion type ignition furnace and a combustion control method thereof. The low-NOx clean combustion type ignition furnace comprises two rows of burners carrying out combustion simultaneously. Each row of burners comprises a fuel gas header pipe, fuel gas branch pipes leading to all the burners, fuel gas valves arranged on the fuel gas branch pipes, an air header pipe, air branch pipes leading to all the burners and air valves arranged on the air branch pipes; the air valves of each row of burners are linkage valves, so that the air flow of the air valves is increased or decreased simultaneously; and the fuel gas valves of each row of burners are linkage valves as well, so that the fuel gas flow of the fuel gas valves is increased or decreased simultaneously. The ignition furnace enables fuel gas and combustion-supporting air to burn in the state of deviating from the chemical equivalent value, so that the content of nitric oxide in exhausted smoke of the furnace is effectively lowered on the premise of not affecting sintering quality and the service life of the furnace, and the effect of clean combustion is realized.
