Hi,

I am sizing a catalytic reforming fired heater. I found several difficulties to find a reference wich present a clear procedure of sizing.

I calculated the efficiency of this fired heater (88.9%). Now, I am trying to size the convective and radiant section.

Could you help me please to find a refrence wich simplify the work.

Hi Fallah

Thank you for help. but i need a guide or references about furnace design.

mhamdi khaled,

 

Then try using the book:

Mr Fallah,
Thanks for help.

Hi,

Designing a fired heater like piece of equipment is not an easy stuff like a shell & tube heat exchanger. I wonder if standard design procedure exist with operating companies, there could be guidelines which can help you in certain aspects of fired heater design but complete design along with instrumentation and all is done by vendors.

I see that this query was asked some time ago, but for the record...

As Mr Padmakar Katre mentioned, the design of a fired heater is very complex and selection of the initial configuration requires understanding of factors such as flux and flow regimes of the process fluid.

 

The design is even more complex for vaporizing process streams.

 

Hysys or Pro II is not capable of simulating a full robust design, but instead there are specialist software tools for the purpose of designing heaters.

 

There is actually a new software available called Heater560, which is the most user friendly software for fired heaters and also produces datasheets, drawings and cost estimates ( more info: see http://www.heatersim.com ).

 

Typically, fired heater design is based on variations of the correlations developed by Lobo & Evans (in the 1940s/1950s). These correlations are quite complex to carry out by hand, as the procedure will involve a number of iterative calculations in order to converge at a reliable design solution.
