The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Note: For questions of the type \"one question per day,\" if a person replies continuously for a month, that is, posts more than 30 times, their score will be assigned as 2 points, which is the lowest possible score. Click once to reply; if multiple replies are made, points will be awarded as appropriate, as deleting posts is also a waste of time. Combustible gases that accumulate inside the furnace or leak due to poor sealing mix with air, and under certain conditions, there is a risk of explosion. Explosion-proof doors are installed in the radiation chamber to allow for timely pressure release in the event of a furnace explosion, thereby protecting the furnace. These explosion-proof doors should be placed in locations where the hot gas released during pressure release does not pose a threat to personnel or surrounding equipment. Scoring criteria: 2 Wealth points for incorrect attempts; 3–8 points for *incomplete* answers. 10 Wealth points for correct answers, provided with a detailed explanation; 15–20 Wealth points if the answer is correct but lacks sufficient details. Please score according to these criteria. Note: If there are editing records after answering, only those who participated will be credited points. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters that have nothing to do with the answer are all considered malicious spamming; points will start to be deducted after three warnings. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Petrochemical Sector – “Creative Ideas for Energy Saving” Campaign (Second phase is in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html 2017 Coal Chemicals – “My Technical Upgrades” http://bbs.hcbbs.com/thread-1786290-1-1.html
During tempering or explosion, it allows the high-pressure gases generated by combustion to be released through the explosion-proof door, preventing the furnace from being damaged and thus serving to protect the heating furnace.
Before the heating furnace is ignited, if the furnace chamber is filled with flammable gases, an explosion can occur upon contact with an open flame or static electricity. In such cases, the explosion-proof door opens, allowing the pressure inside the furnace chamber to be released rapidly and preventing damage to the furnace structure.

Explosion protection--preventing furnace damage.
Answer: Before the heating furnace is ignited, if the furnace chamber is filled with flammable gases, an explosion can occur upon contact with an open flame or static electricity. In such cases, the explosion-proof door opens, allowing the pressure inside the furnace chamber to be released rapidly and preventing damage to the furnace. The purpose of installing explosion doors on heating furnaces is to prevent excessive damage in the event of an explosion in the furnace.
Before the heating furnace is ignited, if the furnace chamber is filled with flammable gases, an explosion can occur upon contact with an open flame or static electricity. In such cases, the explosion-proof door opens, allowing the pressure inside the furnace chamber to be released rapidly and preventing damage to the furnace structure.
1. Before the heating furnace is ignited, if the furnace chamber is filled with flammable gases, an explosion can occur upon contact with an open flame or static electricity. The explosion-proof door then opens, allowing the pressure inside the furnace chamber to be released rapidly and preventing damage to the furnace body； 2. Another solution is to use pilot gas for purging for a certain period of time, usually with the air supplied by the fan
Because when a flash explosion occurs in the heating furnace, pressure is released through the blast door to prevent further damage to the furnace.
