    Finite element heat transfer analysis

    I've not purchased this software myself, but am looking to have it bought for my company's use. Check it out, www.gksol.com it's called EZ-Thermal and works out of Excel. Let me know if you get it and what you think.

    Dry Air Calculations for Work of Compression

    Should be able to get there using one of the Tds equations, second law of thermo, for adiabatic, dS = dQ / T = 0. Then you have TdS = CvdT + RT / V dV which you should be able to integrate from "uncompressed" to "compressed" state assuming that the air behaves like an ideal...

    De-NOx reactor fouling

    I don't have my references here at home with me, but this sounds like NH3 salt deposition (ammonium sulfate and bisulfate) and plugging the catalyst bed. The SO3 formed in the combustion process reacts with injected ammonia to form the salts. At lower temperatures (below maybe 230-250degC)...

    Calculation of Furnace heat duty

    Hi Sansub, not sure what you mean by saying you would like to calculate furnace heat duty. Duty is usually a term associated with the heat absorbed by the process stream that the furnace is providing heat to. In this case, difficult to find a general formula except to say that Qabs = mass flow...
