what per cent is oxidired to P4O10 ? 17. A furnace uses a producer gas of the following analysis: 5.3%CO2,21.1%CO, 15.3%H3,1.0%CH4 and 57.3%N3. . The flue gas contains 14.1%CO4,2.3%O3, and 83.6%N. Both analyees were condueted in an Orsat spparatus with mercury as the confining liquid and were made by a nkilled technician. (a) Aseuming that the analyses are truly representative of the fuel and flue gas, ealeulate, by two different methods, the per cent excess air used in the furnace. (b) A cheok on the history of the gas samples-reveals that although they were analyzed over mercury, each of the two samples was brought from the plant to the laboratory in a container with water as the confining liquid. Recalculate the per cent excess sir in the light of this discovery. they leave the engine) per cubic foot or ar eliverim is operated conventionally with a variety of special fuels. The combere is no reason to question the substantial dependby conventional techniques, and that is the significance to you of the following dats, sbility of the analytical results. (a) A gascous fuel gives a combustion gas containing 6.2%CO2,4.6%O2, and the rest nitrogen (and inerts). (b) A water-white, anhydrous liquid fuel gives a combustion gas containing 16.2%. CO2,4.8%O2, and the rest N2. (c) A pure, solid organic compound gives 15.46%CO2,3.09%O2, and the reat N2
