An 1880 MW wet-bottom, wall-fired sub-bituminous coal power plant emits sulfur oxides, nitrogen oxides, and carbon monoxide into the atmosphere in a rural area. The plant uses coal with a 4% sulfur content. The plant operates around the clock, 365 days a year, 24 hours per day. The 25 m3/s (actual) of exhaust from the plant exits the 1-m-diameter stack at 800°C. The stack is 25 m high. The air pressure within the stack is essentially equal to the ambient air pressure of 1 atm. The average ambient temperate measure at the stack height is 20°C. The average temperature measured at 110 m on a nearby radio tower is 20.0°C. The prevailing wind speed is 2 m/s. Determine:
a. The Ap-42 emission factor for the sulfur oxide, nitrogen oxides, or carbon monoxide (as assigned by your instructor). b. The mass emission rate of the sulfur oxide, nitrogen oxides, or carbon monoxide (as assigned by your instructor) in units of mg/s. c. The plume rise from the stack in m. What will be an ideal response?
