H = 14 Q^{0.3} Where: • H = stack height in metres • Q = total SO₂ emission rate in kg/hr from all boilers connected to the common stack If 3 boilers are connected to one common stack And each boiler consumes 2 litres/hour HSD: Total fuel consumption: 2 + 2 + 2 = 6 litres/hour Take density of HSD = 0.84 kg/litre 6 x0.84 = 5.04 kg fuel/hour Using the same approximation as before: Q = 5.04 x 0.8 = 4.032 kg/hr Now apply formula: H = 14 (4.032)^{0.3} (4.032)^{0.3} =1.52 H = 14 x 1.52 = 21.28m
Therefore , height of the common stack required =22m. RO is requested to ensure the stack height is increasd by the unit and resubmit accordingly. |
