Catalytic flue gas outlet
Thread Content
There is a DN400 pipeline at the outlet of the catalytic flue gas extractor that leads directly to the atmosphere; when will it be able to be used? Thank you so much!
It can be used after stopping smoking. When the exhaust temperature of the flue gas extractor drops below 300°C, this vent is activated to establish a water seal in the outlet water seal tank.
Excuse me, why do we need to wait until it’s below 300 degrees? Thank you!
The temperature is too high; your water seal tank won’t be able to withstand it when establishing a water seal.
We don’t have this line here; the water seal tank hasn’t had a water seal installed since operations started: lol
Without this line, how can the smoke extractor be preheated? The outlet water seal has been removed, so smoke will definitely flow back – how can the temperature be controlled?
Do you vent the smoke at the site while preheating the flue gas system? We open the gate valves and butterfly valves to allow the smoke to flow towards the back of the flue gas system for preheating
At the beginning, the flue gas is vented; once the temperature of the unit rises, the water seal is removed and the venting is stopped. When removing the water seal during preheating, if you start removing it at that moment, smoke will flow back; removing it later will cause blockage
We are on line 80; the outlet is vented – it is activated after shutdown, or before the large water seal is removed, during static warm-up
Used for warming up before starting up; it serves to warm the flue pipes before the high-temperature valve is opened.
We don’t have this wire; there is only a 50 mm vent wire in front of the smoke extractor, behind the dual valves. Is it necessary to use a 400 wire?
