Components of Hydroelectric Power Plant

A hydro electric power plant derives the energy from the force of fast moving water to harness energy. The demand for energy needs has impacted the environment resulting in global warming. Extensive use of non-renewable energy sources like petrol and diesel is the primary reason for environmental pollution. A major shift from non-renewable energy sources to renewable energy sources is the only solution to encounter the rising issue of environmental damage.

**Problem Statement:**
A 35 percent-efficient coal-fired power plant with an effective height of 100 meters emits sulfur dioxide (SO₂) at a rate of 0.6 lb/10⁶ Btu into the plant. If winds are assumed to be 4 m/s at the stack height and just over 3 m/s at 10 meters, how large could the plant be (in megawatts, MW) without having the ground-level SO₂ exceed 365 µg/m³?

**Diagram Explanation:**
The problem is presented in a textual format, and there are no graphical elements associated with it. The problem addresses the calculation of permissible power output from a coal-fired power plant based on its SO₂ emissions and local atmospheric conditions (wind speed).

**Key Concepts:**
1. **Plant Efficiency:**
- The power plant operates with 35% efficiency, indicating that only 35% of the input energy is converted into useful work (electricity).

2. **Emission Rate:**
- The plant emits SO₂ at 0.6 pounds per million British Thermal Units (lb/10⁶ Btu) of energy input. This needs to be controlled to prevent exceeding air quality standards.

3. **Wind Speed:**
- The specified wind speeds influence the dispersion of pollutants from the plant. At stack height, wind speed is 4 m/s, while at ground level (10 m), it is slightly over 3 m/s.

4. **Pollutant Concentration Limit:**
- The ground-level concentration of SO₂ should not exceed 365 micrograms per cubic meter (µg/m³) to comply with air quality standards.

**Objective:**
To calculate the maximum potential power output of the coal-fired power plant in megawatts (MW) such that the SO₂ pollutants do not exceed the permissible ground-level concentration.

A paper plant is proposed for a location 1 km upwind from a town. It will emit 40 g/s of hydrogen sulfide, which has an odor threshold of about 0.1 mg/m3. Assume that winds at 10 m above ground are 2.5 m/s, and at the effective stack height they typically vary from 4 – 10 m/s blowing toward the town. If it is summer day with a few broken clouds, What stack height should be used to assure concentrations are no more than 0.1 times the odor threshold at the near edge of town (1 km away)? To be conservative, the stack will be designed assuming no plume rise. Will any buildings (e.g., the country cabin or the doghouse on the far edge of town) experience higher concentrations than a residence at the 1 km boundary? Briefly explain your answer.
