Calculation of Concentration of SO₂ Emitted from the Power Plant:
Given data:
- Power plant capacity: 1000 MW
- Load factor: 75%
- Efficiency: 50%
- Distance from receptor site: 2 km
- Sulphur content in coal: 5%
- Calorific value of coal: 50 MJ/kg
Step 1: Calculation of Coal Consumption
The power plant capacity is given as 1000 MW, but the load factor is 75%. Therefore, the effective power generated by the plant can be calculated as:
Effective Power = Power plant capacity × Load factor
= 1000 MW × 0.75
= 750 MW
The efficiency of the power plant is given as 50%. Therefore, the coal consumption can be calculated using the following formula:
Coal Consumption = Effective Power / (Efficiency × Calorific value of coal)
= 750 MW / (0.5 × 50 MJ/kg)
= 750 MW / 25 MJ/kg
= 30,000 kg/s
Step 2: Calculation of Sulphur Emission Rate
The sulphur content in coal is given as 5%. Therefore, the sulphur emission rate can be calculated as:
Sulphur Emission Rate = Coal Consumption × Sulphur content
= 30,000 kg/s × 0.05
= 1500 kg/s
Step 3: Calculation of Concentration of SO₂ Emitted from the Power Plant
The concentration of SO₂ emitted from the power plant can be calculated using the following formula:
Concentration = Emission Rate / (Wind speed × receptor distance)
= 1500 kg/s / (3 m/s × 2000 m)
= 0.25 kg/m³
Calculation of Concentration of SO₂ at Receptor Site:
Given data:
- Wind speed at ground level: 3 m/s
- Effective stack height: 150 m
- Stability class: D
- C₁ = 150, C₂ = 50
Step 1: Calculation of Plume Rise
The plume rise can be calculated using the following formula:
Plume Rise = (C₁ × stack height) / (Wind speed) ^ C₂
= (150 × 150 m) / (3 m/s) ^ 50
= 22500 m / 3 ^ 50
≈ 0.045 m
Step 2: Calculation of Concentration of SO₂ at Receptor Site
The concentration of SO₂ at the receptor site can be calculated using the following formula:
Concentration = Concentration at source / (Plume rise / receptor distance) ^ Stability class
= 0.25 kg/m³ / (0.045 m / 2000 m) ^ D
= 0.25 kg/m³ / (0.045 / 2000) ^ D
= 0.25 kg/m³ / (0.0225) ^ D
≈ 0.25 kg/m³ / (0.0225) ^ 4
≈ 0.25 kg/m³ / 0.00001505
≈ 16611 kg/m³
Therefore, the concentration of SO₂ emitted from
Given data:
- Power plant capacity: 1000 MW
- Load factor: 75%
- Efficiency: 50%
- Distance from receptor site: 2 km
- Sulphur content in coal: 5%
- Calorific value of coal: 50 MJ/kg
Step 1: Calculation of Coal Consumption
The power plant capacity is given as 1000 MW, but the load factor is 75%. Therefore, the effective power generated by the plant can be calculated as:
Effective Power = Power plant capacity × Load factor
= 1000 MW × 0.75
= 750 MW
The efficiency of the power plant is given as 50%. Therefore, the coal consumption can be calculated using the following formula:
Coal Consumption = Effective Power / (Efficiency × Calorific value of coal)
= 750 MW / (0.5 × 50 MJ/kg)
= 750 MW / 25 MJ/kg
= 30,000 kg/s
Step 2: Calculation of Sulphur Emission Rate
The sulphur content in coal is given as 5%. Therefore, the sulphur emission rate can be calculated as:
Sulphur Emission Rate = Coal Consumption × Sulphur content
= 30,000 kg/s × 0.05
= 1500 kg/s
Step 3: Calculation of Concentration of SO₂ Emitted from the Power Plant
The concentration of SO₂ emitted from the power plant can be calculated using the following formula:
Concentration = Emission Rate / (Wind speed × receptor distance)
= 1500 kg/s / (3 m/s × 2000 m)
= 0.25 kg/m³
Calculation of Concentration of SO₂ at Receptor Site:
Given data:
- Wind speed at ground level: 3 m/s
- Effective stack height: 150 m
- Stability class: D
- C₁ = 150, C₂ = 50
Step 1: Calculation of Plume Rise
The plume rise can be calculated using the following formula:
Plume Rise = (C₁ × stack height) / (Wind speed) ^ C₂
= (150 × 150 m) / (3 m/s) ^ 50
= 22500 m / 3 ^ 50
≈ 0.045 m
Step 2: Calculation of Concentration of SO₂ at Receptor Site
The concentration of SO₂ at the receptor site can be calculated using the following formula:
Concentration = Concentration at source / (Plume rise / receptor distance) ^ Stability class
= 0.25 kg/m³ / (0.045 m / 2000 m) ^ D
= 0.25 kg/m³ / (0.045 / 2000) ^ D
= 0.25 kg/m³ / (0.0225) ^ D
≈ 0.25 kg/m³ / (0.0225) ^ 4
≈ 0.25 kg/m³ / 0.00001505
≈ 16611 kg/m³
Therefore, the concentration of SO₂ emitted from
