In an oil fired boiler the fuel had an analysis by mass: carbon 84%, Hydrogen 11%, Sulphur 3%, and Oxygen 2%, remained incombustible. The analysis of dry gas flue gas by volume gave: combined CO₂ 9.7%, CO 0.5%, O₂ 2.95%, and N₂ 86.85%, there being no SO₃. Calculate per kg of fuel: 1- Mass of air supplied. 2- Percentage excess air supplied. 3- Mass of flue gas formed. 4- Mass of water vapor formed.

A fire-tube boiler made from carbon steel in which fuel gas flows within the tube while the boiler feed-water along with condensate from the plant flows on the shell-side. Visual inspection revealed heavily localized tubercles were seen on the outside surface of several tubes. After about 11 months of operation, the pipe was leaked and visual inspection found pin holes outside surface contain loose brownish rust. The rust contained chloride and was acidic in nature. Select appropriate corrosion prevention to...

An organic compound contains carbon, hydrogen, and sulfur. A sample of it with a mass of 2.712 g was burned in oxygen to give gaseous CO2, H2O, and SO2. These gases were passed through 311.2 mL of an acidified 0.0200 M KMnO4 solution, which caused the SO2 to be oxidized to SO42-. Only part of the available KMnO4 was reduced to Mn2+. Next, 31.12 mL of 0.0300 M SnCl2 was added to 31.12 mL portion of this solution, which still...

An iron boiler of mass 180 kg contains 730 kg of water at 11 ∘C. A heater supplies energy at the rate of 58,000 kJ/h. The specific heat of iron is 450 J/kg⋅C∘, the specific heat of water is 4186 J/kg⋅C∘, the heat of vaporization of water is 2260 kJ/kg⋅C∘. Assume that before the water reaches the boiling point, all the heat energy goes into raising the temperature of the iron or the steam, and none goes to the vaporization...
