Doubts regarding the temperature of the catalytic flue gas turbine disc
Thread Content
During the initial stage of warming up for catalytic operation (when the temperature of the regenerated flue gas is 150°C), the temperature of the flue gas turbine rotor reaches around 300°C. How can this be explained? (There’s a dead zone in the current flue gas turbine, right?) Is this normal? I hope to receive guidance from all the teachers. Thank you!
I don’t quite understand this; surely some expert will come and help.
How is that possible? At the beginning of operation, the flue gas hadn’t even reached the rotor yet! I guess it’s because the steam cooling system for the wheel has been turned on; the temperature is raised by the steam
Is it the temperature of the cooling steam in the wheel?
The temperature is too high; we’ve started using the smoke machine wheel steam! The steam is already at a high temperature even before it is put into use; so what is considered a normal temperature?
Don’t you need a backup machine during the heating-up phase? Turn on the smoker directly?
Look closely; he said it’s a dead zone!
Could it be that the tail is on fire? Is the air supply too low? Is the vent at the smoke extractor inlet open at this time?
Is it steam leakage? There’s a high-temperature gate valve at the smoke extractor inlet. Besides, the temperature of your regenerator is only 150 – that’s impossible
No need for a backup machine – just turn on the main unit! During the startup heating phase, the flue gas fan is in a dead zone!
We are currently using auxiliary combustion chambers to heat the two vessels; the vent is set at a slightly higher level (though there are electric gate valves and butterfly valves at the flue gas inlet as well). Moreover, this happens only when the temperature in the regenerator reaches 100°C!
