    sensible energy calculation of flue gas

    On more question, if i may: can you please tell me the title of the literature that has the information regarding the kJ/kg for the gas components? Is this literature available on the internet? I would like to get the data for H2O too. Thanks again, MH

    sensible energy calculation of flue gas

    Thank you very much. I am now 7 years retired but still interested in reading literature. I found some articles which talked about chemical and sensible energy and i wanted to understand how that is beeing calculated. Thank you for your assistance and explanations. best regards, MH

    sensible energy calculation of flue gas

    Thanks again, but now i am more confused: can you detail how you got to the mass%, kJ/kg for O2? How did you get to 722 and what dimmension is it? I divided 2/32 to get to the molar mass of O2 at this example of 0.0625. Doing this for all components, i get a total molar mass of 5.0533, and...

    sensible energy calculation of flue gas

    Hu is the chemical energy content of an off gas and is calculated only with components that generate energy such as CO, H2 and CH4. I believe strongly that this is correct. I now try to calculate the sensible energy of an electric arc furnace When both are shown as a chart, the operator of an...

    sensible energy calculation of flue gas

    Thank you for this information. Can you please check attached spread sheet and tell me that i am on the right track? Once i have calculated the Q for each gas component a just add them up and get Q for the...

    sensible energy calculation of flue gas

    Seasar, well, it should be accurate since we want to calculate the energy balance of an electric arc furnace. dT is about 300 - 700 deg C at the point we measure the gas flow, temperature and composition. Any additional thoughts? Thank you in advance for your valuable imput!

    sensible energy calculation of flue gas

    seasar, Thank you for this information. I was worried that i have to use the equations recommended by NASA Glenn Coefficients /TP-201-210959/Rev1 to calculate the enthalpy.

    sensible energy calculation of flue gas

    Hi, I need to calculate the sensible energy content of a flue gas with the following composition and temperature: 2% CO, 27% CO2, 2% O2, 4% H2 and the balance is N2. The gas temperature is 650 deg C and the volume is 145000nM^3/h. Can somebody tell me how to calculate the sensible energy...

    Maximum Heat Load For 2 1/2 Inch Pipe

    I need to calculate the maximum heat load for a 2 1.2 inch pipe, schedule 80 and 160 that is water cooled and exposed to an electric arc. Any formula or figure ( kw/m^2.h ) known?
