One of your fellow Energy Engineers comments that the flue gas leaving the natural gas-fired boiler that you are designing must be at a high temperature because of dew point. Your boss asks you to analyze that argument by performing some calculations. The natural gas boiler that you are designing utilizes a gas with a composition of CH4-95% and C2H6 - 4% and other inert gases 1%. You have a coal fired facility next door as well as they use a coal with the following analysis C-73.4% H-4.3%, S-1.1%, N-1.3%. The fuel's proximate examination is given as follows: Moisture 6.8%, Ash-8.6%, FC- 65.4 and VM 19.2%. The HHV of the Fuel is 13,380 BTUs/lb. The air that is utilized is ambient at 78 F and 40% relative humidity. This plant is designed to utilize 22% excess air. Compute both cases and show to your boss with computation whether the dew point is different?
