Accuracy of temperature selection in pressure vessel design
Thread Content
Dear teachers: In the design of pressure vessels, the temperature of steam distribution cylinders is sometimes determined using difference methods; it is necessary to decide whether to use an integer value or to retain a decimal value. Thank you for the advice! Wish kind people happiness forever!
The temperature at normal saturated steam pressure is determined using a difference calculation. For the steam in the distribution cylinder, since there is always heat loss from the boiler outlet to the distribution cylinder, I believe the design temperature for this cylinder should be an integer.
In principle, it should be rounded up; for example, 32.1 becomes 33
Thank you to the teachers upstairs for their guidance. I just think this: as long as the temperature is not near the relevant control temperature, round it up. This is more conducive to the safety of the equipment. I’m not sure if that’s correct? Please ask the teacher for guidance. Thank you!
I wouldn’t dare call myself a teacher, but rounding the design temperature upward is the correct approach; there are specialized calculation software tools available, so there’s no need for some so-called alternative methods.
