3. Consider a new 1800 MW power plant that burns dry sub-bituminous coal in a PC-wall-fired,
wet bottom furnace with plant efficiency of 39%. Use the emission factors in your lecture
notes to determine the emission rates of all particulates, PM10, SOx, NOx and CO in ton per
year. No gas treatment equipment was installed.
1. The particulate emissions were measured from a factory stack. The stack was divided into
three sectors with different cross-sectional areas. The measured velocities and particulate
concentrations were given below.

a) What is the average particulate concentration in mg/m³?
b) What are the particulate emissions per unit area in g/m²-s for sector number 1, 2 and 3?
c) What are the flow rates of particulates in g/s for sector number 1, 2 and 3?
An urban county with an area of 1,000 mile² has an estimated 18 million miles of vehicular
traffic per day and has a large power plant. The power plant produces 350 MW of electricity
at an efficiency of 39%, burning 10,000 Btu/lb coal. The vehicle emission factor for VOCs is
6 grams/mile; the coal-fired boiler emission factor for VOCs is 1.4 lb/ton coal; biogenic
emission of VOCs is 0.4 kg/km²-hr on the average. Determine the total emissions of VOCs in
tons/day from all sources (mobile, power plant, and biogenic).

- For automobile, gasoline is a complex mixture of relatively volatile hydrocarbon blended for use in spark-ignition engines. Every time fuel is burned, the carbon is converted to carbon dioxide (CO2), the natural end product of combustion. If we approximate the chemical formula for gasoline by the compound octane (C8H18) with a density of 739 grams/liter, the stoichiometric reaction for complete combustion is: C8H18 + 12.5O2 8CO2 + 9H2O Thus, for every mole of C8H18 fuel that is burned, eight moles of CO2 are produced, along with nine moles of water vapor. Estimate the CO2 emission in grams per mile for a car getting 12 km/liter of gasoline.arrow_forwardThe farming plan of steel structure has 30 ft long simply supported beams spaced at 8 ft apart.
