This post was last posted by Haitian LSHW on 2011-4-20 08:14. I came into contact with some content about chimneys during my editing work. I don’t know much about chimneys. I don’t know if there is a standard series of chimney specifications. What manual can I find relevant content? Please help, thank you! Reading some content about chimneys, it is mentioned that the chimney exit velocity is 20~30m/s. Through this flow velocity, the outlet diameter can be calculated. How is the bottom diameter of the chimney considered? Is the flow velocity of the flue considered? There is also the slope of the outer wall of the chimney. How is it determined? The calculations in the "Chimney Engineering Manual" all give the top diameter and height, and the calculations are based on them. So which major determines the top diameter, bottom diameter and height? This post was last edited by Haitian LSHW on 2009-4-16 08:11 ]
The author should refer to these two standards to learn* Take a look at GB50078-2008 "Code for Construction and Acceptance of Chimney Engineering" GB50051-2002 "Code for Chimney Design"
Chimney Engineering Manual http://bbs.co188.com/content/0_880586_1.html
Station Chimney Engineering Manual If it is a furnace chimney in the petrochemical industry, you can refer to the interpretation of JB4710-92 "Steel Tower Vessel" for structural calculations. For other industries, you can refer to 2#. Wind load follows GB50009-2001 "Load Code for Building Structures". If you need to set up a wind break circle, you can refer to section 9.5 of API 560 "Fired Heaters for General Refinery Services" on the site for calculation.
