Hi every body,
Do you know a software for fired heater design?

Aspen Fired Heater: http://www.aspentech...FiredHeater.pdf
Technip Spyro (Steam Reformer furnace): http://www.technip.c...oc/ETHYLENE.pdf
HTRI: http://www.htri-net....roducts/Xfh.pdf

Also Jehar&Associates produces the WinHeat Suite.

Dear,
Djack has given a useful link the WinHeat Suite is free and useful one.

Hi,

Yes, you could use HTRI, and especially HTRI Xfh software (see attached file) which is designed for this application.

Hi,

I've used HTRI xFh and the results did not match an existing furnace (very simple furnace actually!). The pressure drop estimation was way off. I presonally will not use it for design work unless its conceptual

The software that I've seen is the one from KTI (originally made by chevron I guess) its FRNS5 (spelling ?), I have used it with KTI for several studies and its very good. It may not be cheep !

KTI is now part of technip,

cheers,

hi smalawi
could you please to send mentioned produced software by KTI to my email address. my email address is as follow:
deldary74@yahoo.com

Sorry, I dont actually have the software with me

Also, like all such software, they are protected

Hi

Smalawi did you have a chance to try HTFS tools for fired heater?

Hossein Deldari, the software is protected so I can not send it to you, sorry.

Hi,

I have access to it but did not use it in real heater design. I would be reluctant to do so, this software could be good for rating and preformance checking but not actual design.

Prehaps you can ask this question directly to Aspen and ask them to include some referances.

Regards,

Smalawi, that is an interesting statement. I haven't had any experience in fired heater design, and I was wondering if you can clarify your previous post, by writing in more details. Why the same software could be suitable for rating, but not for design calculations? These things usually go in parallel.

In other words, if the same software is used for design (not reliable) and rating (reliable?), then you can actually rate your heater design by using the same software, and see if all the criteria are being met. If design procedure is not accurate, I would expect rating calculations/algorithms to be inaccurate as well.

Ratign and design are two very deferent things. In rating you could tune parameters to match reality and its typically not a very critical process, unlike design. Prehaps this could be less of an issue for simple steam reboilers, or small services with low duties.

If you look at heater vendors they all use their own software or methods they used and established experaince.

I have good expriance with FRANC5 and other major EPC contractors, these programs work, are based on expriance and used by experts

I cant assure you that the Aspen software is good, I dont have expriance with it. If you read the first line in the linked supplied, you will see rating ! Can it be used for design, maybe, but who will ensure the results, Aspen wont but EPC contractors will do

One software that I used and believe is giving suprizingly good results that match reality (in CDU / VDU's) is KBC petro-sim furnace model. Its not advertised for desgin by I believe the origins are for design.


Presonally, I will not deisgn a heater by general softwares and rather give it to a specilist. If you want just an estimate for master planning, just qute a vendor directly.

Hope this clarifies,

Cheers,
