Calculation in environmental impact assessment.
Boiler flue gas calculation: 1Kg coal produces 8.5m3 flue gas (experience); chain furnace 1 Kg coal produces 10.35m3 flue gas
Source strength calculation formula: SO2： \(Q =G \times 2 \times 0.8 \times S \times （1-EtaSO_2）\)
Where: G-calcium consumption; S-coal sulfur content;
EtaSO2-desulfurization efficiency, 40% of the water bath and water film, and 90% by limestone-gypsum method.
Smoke: \(Q=G \times A \times EtaA \times (1-Eta)\)
Where: G-consumption coal consumption;
EtaA - the percentage of fly ash in coal that accounts for ash;
Eta-dust removal efficiency
|Furnace type||ηA||Furnace type||ηA|
|Hand burner||15-25||Boiling furnace||40-50|
|Chain furnace||15-25||Pulverized coal furnace||75-85|
|Reciprocating furnace||20||Vibration grate||20-40|
|Coal smelter furnace||25-40|
G— Coal consumption: 100
S—Sulfur content in coal: 10
Etas - Desulfurization efficiency: 8
A—ash in coal: 15
EtaA - Percentage of fly ash in coal as a percentage of ash: 0.8
Eta - Dust removal efficiency: 0.5
