The invention relates to an automatic ignition control method of a closed combustion furnace, in particular to the automatic ignition control method of a closed container such as the combustion furnace or a claus furnace, and belongs to the technical field of automatic control of combustion furnaces. According to the automatic ignition control method of the closed combustion furnace, whether various technological conditions meet the ignition demand or not is intuitively shown, one-key ignition operation is conducted and is responsible for monitoring whether the various technological conditionsare met or not and conducting operations such as starting, ignition, sudden stop and reset, in the case that ignition is not successful, a clear step hint is given, so that operators make a clear judgment, the progress of each step in the ignition process is shown, and the ignition efficiency and the success rate are improved.
