A device to mitigate hydrogen explosions in a vacuum furnace includes at least one igniter, an ignition transformer, and an electrical switch. The at least one igniter includes a set of high-voltage electrodes and is connected to the ignition transformer by high-voltage wires. The electrical switch activates the ignition transformer to provide power to the at least one igniter forming a continuous electrical arc between the electrodes. The at least one igniter is located inside the vacuum furnace at an opening where air may enter the vacuum furnace, which may contain a hydrogen and steam gas mixture under accident conditions. The device consumes hydrogen by controlled combustion as flammable mixtures are formed.
