[Q&A Question No. 0665] Why is it necessary to use steam for purging first when restarting a furnace after it has stopped working? 2018.03.07 When the furnace goes out during operation, some gas remains inside the furnace chamber. If this remaining gas is not purged, an explosion can occur when attempting to restart the furnace. Therefore, before restarting it, the remaining gas must first be purged using steam. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limits on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

Blow out the remaining flammable gases to prevent re-ignition and the occurrence of an explosion when the explosive limit is reached
Answer: When the furnace goes out during operation, some gas remains inside the furnace. If this gas is not blown away, an explosion can occur when attempting to restart the furnace. Therefore, steam is used for purging first before restarting it

Blow out the remaining flammable gases to prevent re-ignition and the occurrence of an explosion when the explosive limit is reached
Blow out the combustible gases from the furnace to prevent re-ignition and flash explosions
When the furnace goes out during operation, some gas remains inside the furnace. If this gas is not purged completely, an explosion can occur when attempting to restart the furnace; therefore, steam is used for purging first before restarting it.
Even after the furnace is turned off, some combustible gas remains; if it is not purged before re-ignition, an explosion is likely to occur
When the furnace goes out during operation, some gas remains inside the furnace chamber. If this remaining gas is not blown away, an explosion can occur when attempting to restart the furnace. Therefore, it is necessary to use steam to purge the remaining gas before attempting to restart it.
