Seeking advice: Is the design of a boiler slag bin the same as that of a regular steel plate silo?
Thread Content
For example, a silo with a straight cylindrical section that is 10.6 meters high and 6 meters in diameter, and a conical section that is 4.8 meters high. The equipment manufacturer uses the same thickness for both the straight section and the conical section, which is 10 mm thick. Our boss asked if it was too thick and suggested looking up the relevant standards. If it were a regular steel silo, with a design temperature of 200 degrees, 8 mm would be sufficient according to calculations; however, I have asked several silo manufacturers, and they all use a thickness of around 10 mm. Is there any particular way to say this?
Yes, there is. This should be designed in accordance with the silo specifications. Thickness is related to wind and seismic loads; it is not necessarily the same for all cases. It needs to be calculated.
The wall thickness is calculated, not photographed. You can take a look at the standard NB/T47003.2 \"Solid Silos\", which contains example problems that can serve as a reference.
Actually, 8mm is also fine for this device; setting the thickness of the reinforcement ring is a more cost-effective option.
Mm-hmm, I know that. I didn’t explain it clearly enough; by 8 or 10, I meant the thickest parts. It’s mainly a matter of following which standards
Well, I have been studying this standard for a long time, and the formulas are presented in tabular form. Are there any other specifications regarding the slag bin?
Well, calculated based on 47003.2, 8 is fine; the verification will also pass. But I want to ask if the slag bin has its own standards.
Yes. Grain silos, cement silo specifications, etc.
:Well, as for these standard numbers, I know of 47003 and 50884; I really don’t know any others

Little Rabbit, are you still on the forum? Do you use the oblong holes in the bolts of your 200-degree bearings [8-12 bearings] to allow for thermal expansion? It seems like using the online form: 2mm material + 4mm wind resistance
