Description

Technical Field

[0001] This utility model relates to the field of ignition technology in oxygen-deficient environments, and in particular to an ignition device. Background Technology

[0002] Currently, during the routine start-up of an acetylene cracking furnace, it is necessary to perform auxiliary oxygen ignition. During start-up, the furnace is filled with natural gas, and a small amount of auxiliary oxygen is released from the furnace top to maintain a slight positive pressure inside the furnace. At present, the auxiliary oxygen ignition operation needs to be manually performed outside the furnace, requiring three people to work together. A hollow ignition gun is inserted into the furnace to draw natural gas from inside the furnace and ignite it with an open flame. Then, an oxygen hose is connected to send the flame into the furnace. Outside the furnace, the ignition gun is moved around to ignite the auxiliary oxygen area in the furnace top region with a stable burning flame.

[0003] Improper operation during auxiliary oxygen ignition can easily lead to burns and scalds on operators, and may even cause flammable gas explosions, posing safety risks. Therefore, it is necessary to develop a safe and reliable ignition device for acetylene cracking furnaces operating under oxygen-deficient conditions. Utility Model Content
