How to calculate the radiant heat of an elevated flare and the ground concentration?

2008-02-18View Original

Thread Content

It is necessary to calculate the radiant heat and deposition concentration at various distances from the torch. I was wondering if anyone could provide some clues or suggest some software that can do this? :handshake :handshake Last edited by 15778 on 2008-2-18 10:07]

The SH3009-2001 Standard for the Design of Fuel Gas Systems and Flammable Gas Emission Systems in Petrochemical Enterprises contains calculation formulas; there are also many relevant explanations and small software tools available on forums – you can search for them on your own.

I searched for the standards but couldn’t find any. Could someone on the 2nd floor provide more detailed information, including details about the software? Thank you

I have already seen this standard before, and it doesn’t contain any calculation methods for the radiant heat at different distances from the torch, nor for the concentration of heat at the ground level. . . A small software? ? I really need it! Can you provide it? I couldn’t find it~

The SH 3009-2001 standard only contains formulas for calculating the outlet diameter and height of the flare stack, but not the formulas I need.

This is quite useful, and its interface is also simple and user-friendly. I just wanted to ask what is meant by the \"land acquisition boundary length\" in the \"calculation of land acquisition area for torch height\"? Is it the straight-line distance from the center of the flare stack to the range affected by the flare? Is that the radius of the accessible area around the torch?

Really, no one understands the specific algorithm? Feeling down~:Q

I’ll highlight it for 3 days to see if any experts can help you solve it. Also, since the original poster is already in fourth grade, I hope you’ll reward those who help answer your questions by giving them ratings, so as not to let their efforts go to waste; this will also maintain people’s enthusiasm for answering your questions.

Does “the length of the land acquisition boundary” refer to the “straight-line distance from the center of the flare tower to the area affected by the flare”, that is, the radius of the flare tower’s safe zone? The calculation for the torch height and land acquisition is as follows: http://www.bzjs.net/bzjs/middle.asp?id=129

The SH3009-2001 Standard for the Design of Fuel Gas Systems and Flammable Gas Emission Systems in Petrochemical Enterprises contains calculation formulas; one of these formulas is used to determine the height of the flare based on the radiant heat. So why can’t we calculate the radiant heat once the height is known? After all, there’s no data regarding the concentration at the ground level! I carried out the calculations in this way, and the results were fairly satisfactory. Additionally, API 521 also provides specifications regarding flares!

It’s not that I don’t want to give a rating; I just don’t know why I can’t. Every time I try to score, it shows something like “Your request came from an unauthorized source or the verification string is incorrect.” I’m not sure why – could it be the firewall? Let me answer it by the way. I’ve been confused for a long time. This post was last edited by 15778 on 2008-2-26 10:18]

  First of all, I’d like to thank all the TX users for their generous help; even the moderators could no longer stand my being such a \"stingy\" person. . . Hehe, it’s not that I don’t want to give scores to everyone; I just don’t know why I can’t do it. I’ve already sent a message to the moderator, and as soon as I find a solution, I’ll give points to those who helped me. Thank you!   According to the flare height formula in SH3009-2001, it is theoretically possible to determine the total radiant heat emitted by the flare. However, please note that what I need is the radiant heat at different distances from the center of the flare; for example, the radiant heat at a distance of 2 meters from the flare Radiant heat at 10m from the torch?   I consulted several colleagues; some said it could be derived using fluid dynamics, while others mentioned that there are specialized software tools available, but no one has actually used them, so it’s difficult to draw any conclusions. . .   I am still confused. . .

The Chemical Process Design Manual (4), edited by Wang Songhan, contains calculations for harmful floor concentrations. But please check – the two formulas before and after seem to be contradictory.

Friends in the storage and transportation field, does anyone know anything about the technical specifications regarding the height of ground torch towers?

SH3009-2001 Code for Design of Fuel Gas Systems and Flammable Gas Emission Systems in Petrochemical Enterprises; the American Petroleum Institute’s AP521 also contains relevant regulations and requirements.
