There’s a ghost in the flue gas duct of the coking plant! ! ! ! ! !
Thread Content
The flue damper broke after just two months – it’s terrifying. Material of the damper: cast from ordinary casting material [mullite]； The skeleton is made of stainless steel. Components of the flue gas: oxygen, carbon dioxide, carbon monoxide, hydrogen, nitrogen oxides, etc. It should be an oxidizing atmosphere. Temperature: 1000°C. Height of the baffle: 4.75 m ； 2.7m wide ； Are there any other lightweight casting materials with a thickness of 200 mm? Or other fire-resistant material baffles – could you recommend some? Dear sea friends, I wish you a happy New Year in advance!
Is there a master who can help? Waiting online for answers
Could it be that the expansion joints are not sufficient? Consider that
It’s either a problem with the material or a problem with the casting.
Master, could you explain in more detail? I don’t quite understand 3# houtuci888
Could anyone tell me what material should be used for casting? It’s best to be lightweight
1. Was the masonry constructed in accordance with the plans, and were expansion issues taken into account? 2. Is the actual flue gas load equal to the designed load? If it is too high, severe local wear may occur (due to high flow rates)
Issues with temperature and outlet pressure – what is the flue gas volume?
Bro, this was a question from five years ago……
