【Q&A Question 203】July 22, 2017: What explosion-proof measures are in place in the heating furnace system? The reference answers will be visible after responding; scoring is based on identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) ① The furnace is equipped with a steam purging line. ② A flame arrester is installed on the gas line. ③ An explosion-proof door is installed on the furnace body. ④ A perpetual light is installed inside the furnace. Scoring criteria: 2 Wealth points for incorrect responses; *incomplete* answers earn 3–8 points. 10 Wealth points for correct answers, provided along with a detailed explanation; responses that are correct but lack sufficient details earn 15–20 Wealth points. Please score according to these criteria. Note: If there are editing records after answering, only points will be awarded to those who participated. 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
1) Furnace fire-extinguishing steam line； 2) The flame arrester prevents backfire ； 3) The eternal flame prevents explosions that may occur when air is introduced again after a gas supply interruption ； 4) Explosion-proof vent door for pressure relief.
1\ Furnace fire-extinguishing steam line; 2\ Flame arrester to prevent backflow of flame; 3\ Pilot light to prevent explosion when gas is reintroduced after a supply interruption; 4\ Explosion-proof door for pressure relief.
1) A steam purging line is installed in the furnace to purge combustible materials from it before ignition. (2) Fire-fighting steam lines are installed in the convective chamber tube bank to provide protection or for extinguishing fires in case of oil leakage or ignition at the elbows. (3) Install a flame arrester on the furnace gas line to prevent backfire ignition. (4) A pilot light is installed in the gas furnace to prevent explosions when gas is reintroduced after a supply interruption caused by faults in instruments or similar devices. (5) On the furnace body, there are varying numbers of explosion-proof doors installed according to the volume of the furnace chamber; these doors serve to release pressure in case of a sudden increase in pressure inside the furnace, thereby preventing the furnace body from exploding.
① The furnace is equipped with a steam purge line. ② A flame arrester is installed on the gas line. ③ An explosion-proof door is installed on the furnace body. ④ A perpetual light is installed inside the furnace.
