PROCEDURE FOR CALCULATING POWER PLANT EMISSIONS   By: Marcial T. Ocampo house 17, 2009     Calculating power lay emissions (mg SOX / Nm3, mg NOX / Nm3, mg CO / Nm3 or as ppmv SOX, ppmv NOX, ppmv CO) is sometimes difficult for routine power plant engineers.  Carbon dioxide emissions be usually tending(p) in % by glitz dry or as kg carbonic acid gas per kWh generation.   Well, your favorite aught technology well(p) has developed a spreadsheet lay (in MS Excel) for calculate in a breeze the common power plant emissions.   SO2 and CO2 emissions are readily calculated from fuel summary (by large number for solid and liquid fuels, by volume for gaseous fuels) and typically calculated by Orsat or different gravimetric methods.   On the other hand, NOX and CO are result of thermal dissociation of N2 into NOx at higher(prenominal) burning at the stake temparature enchantment CO is the result of incomplete combustion due to substandard O2 or inadequate fuel and line of credit mixing.  Hence, NOX and CO are metric using instruments and later computed as mg NOX / Nm3 or mg CO / Nm3).   (Nm3 means popular cubic meter of gas).   The basic stairs followed by my model are as follows:   Basic step:   1) Input subjective gas (fuel) analysis: % volume (same as % mol), molecular weights: e.g. H2, CH4, C2H6, C3H8 ... CO2, S, O2, N2, water system moisture, ash.

    2) Convert % volume to final analysis % big money or weight (%C, %H2, % S, % O2, %N2, %water system moisture, ash)   3) From the combustion equations;   C + O2 = CO2 S + O2 = S02 H2 + 1/2 O2 = H20   ! calculate the stoichiometric O2 in mols and lbs and that of N2 from air analysis.   4) victimisation the tautologic %O2 wet basis measurement in the good serving gas, the level of wastefulness air ratio is computed. Use this excess air ratio to compute actual excess mob of O2 and N2 to compute the total flue gas (fuel + air).   5) Convert the atomic reactor to mols using their molecular weights and convert to % volume. The computed %O2 must tally with the measured %O2 wet...If you want to get a full essay, order it on our website: OrderCustomPaper.com
