Exhaust Gas Calculations - Who Can Do Them?
Exhaust Gas Calculations - Who Can Do Them?
(OP)
We are replacing 2 existing 6.5MBTU Boilers with 6 2MBTU 2 stage boilers. We would like to use the existing stack but have some concerns weather it will work properly. We need to know what the minimum amount of boiler stages we need on to create enough flow and if we will have condensation issues. We basically need a professional engineer to do exhaust gas calculations to determine if our design will work, and if so what are the appropriate operating parameters. Can anyone help us find someone with this?

Be careful. Have you checked with any large, reputable boiler manufacturer (B&W, AP, Foster Wheeler) or are you engineering this retrofit internally to your organization with help from an outside AE firm?
If it were me, I would directly contact a reputable boiler manufacturer that has design/fabricate/construct capability and either has or can get access to computer modeling systems to evaluate flue gas temperatures and drafts to retrofit an existing facility.
I would be hesitant to rely on an AE firm unless they have demonstrated experience in the Power Generation industry.

Two of the AE firms that we have used are Black and Veatch and Sargent and Lundy. I am not formally endorsing these companies, just telling you that we had used them in the past. My only advice is that you need to make sure that the personnel they assign to perform this modeling have the proper experience - a PE credential alone will not suffice. Check references and past jobs before signing any contract!
There are smaller boiler modeling firms that have been started by former CE and B&W engineers. This could be an option for you, but again check references!!!

Is this a feasible plan? I'd be interested in the calculations mentioned.

What is the current temp at the breeching of the 2 original boilerS and what type of a stack do you have?
