Fired Heater

Fired Heater

Fired Heater

(OP)
Dear All,

While reading Mechanical Datasheet of existing Fired Heater package, We found that vendor/Manufacturer has taken ambient temperature 25C for Stack design and 50C for the rest of fired heater to design.

Please could someone explain to me what was the reason for these two different temperatures taken for design for one fired heater.



Best regards,

Did you ask the vendor/manufacturer?

RE: Fired Heater

Maybe one is min for expansion and the other max for thermal or air temerature?

Remember - More details = better answers

Dear All.

Thanks for your reply, I asked the vendor and I am waiting for response.

RE: Fired Heater

I'd imagine the combustion air that moves fast and is fresh air drawn rapidly into the system is 25C while air around the equipment and stack is 50C.

RE: Fired Heater

With lower ambient temperatures considered for stack design we can expect more stack thermal losses and accordingly it would be more conservative approach for estimating the efficiency.

White Paper – Your Construction ERP RFP Checklist
Selecting business software for a medium to enterprise-sized construction concern is extremely challenging in large part because most enterprise resource planning (ERP) suites originated in the world of repetitive manufacturing and are therefore a poor fit for a project and asset-centric business. However, midsize to large contractors need the predictable, auditable processes that ERP delivers. Download Now
