Problem of catalyst temperature rise due to short-term parking conversion
Thread Content
For short-term (two-day) parking, the catalyst temperature rises from 200 degrees to 420 degrees. Is everyone following the temperature rise curve?
It mainly depends on the condition of your equipment; you don’t need to worry too much about the catalyst. Twenty or thirty degrees per hour is fine too, if you can manage that.
If raised by 200 degrees, it will take four hours to complete. Will it have a significant impact on the equipment and catalyst?
It is not necessary to follow the heating curve; an increase of 20-30° per hour is sufficient
An increase of around 20-30 degrees per hour is sufficient; it’s better to do it slowly rather than quickly
There are regulations: the temperature should not increase by more than 25 degrees Celsius per hour, and the pressure should rise by 0.1 MPA per minute. This is common sense
The question is why does a short stop need to heat up. Should the temperature be kept constant at a lower level? Isn’t a helicopter afraid that the catalyst will get damaged? Why not control it? I don’t understand
My understanding is that after two days of short-term parking, the catalyst temperature drops to 200 degrees; it needs to rise to 400 degrees to reach the temperature required for normal catalyst operation. I’m not sure if my understanding is correct
Before stopping the operation, blow hot air for 2 hours. After turning off the fan, close the inlet and outlet valves of the fan; if there are valves at the end of the exhaust pipe as well, close them as well, in order to minimize the loss of hot air. The temperature can be increased at a rate of 30 degrees per hour, and it will take only 6 hours to reach the desired temperature
