Table 16: Stack height requirement for SO 2 control Power generation capacity Stack height (m) Less than 200/210 MWe H = 14 (Q)0.3 where Q is emission rate of SO 2 in kg/h, H = Stack height in metres 200/210 MWe or less than 500 MWe 200 200 500 MWe and above 275 (+ Space provision for FGD systems in future)
The height limit was passed by the United States Congress in 1889 as the Height of Buildings Act of 1899 and later amended by the Height of Buildings Act of 1910. [ 28 ] [ 29 ] Boston , Massachusetts: Due to the city's proximity to Logan International Airport , building height is restricted to around 800 ft (240 m).
Functions of CPCB comes under both national level and as State Boards for the Union Territories. CPCB, under the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, aims to promote cleanliness of streams and wells in different areas of the States by prevention, control and abatement of water pollution, and to improve the quality ...
Reference [10] explains how the NPL affects the stack effect in high-rise buildings. For flue gas stacks or chimneys, where air is on the outside and combustion flue gases are on the inside, the equation will only provide an approximation. Also, A is the cross-sectional flow area and h is the height of the flue gas stack or chimney.
The United States also limits the maximum height of a flue gas stack to what is known as the "Good Engineering Practice" (GEP) stack height. [8] [9] In the case of existing flue gas stacks that exceed the GEP stack height, any air pollution dispersion modelling studies for such stacks must use the GEP stack height rather than the actual stack ...
Maximum limits are 2.7 grams per kilometre (4.35 g/mi) of CO, 0.39 grams per kilometre (0.63 g/mi) of HC, and 0.48 grams per kilometre (0.77 g/mi) of NO x. One interesting detail of the Japanese emissions standards was that they were introduced in a soft manner; that is, 1978 model year cars could be sold that did not meet the 1978 standards ...
The height of a flare stack, or the reach of a flare boom, is determined by the thermal radiation that is permissible or tolerable for equipment or personnel to be exposed to. [11] For continuous exposure of personnel wearing appropriate industrial clothing a maximum radiation level of 1.58 kW/m 2 (500 Btu/hr.ft²) is recommended.
Notes: 1 atm = absolute pressure of 101.325 kPa or 1.01325 bar; mol = gram mole and kmol = 1000 gram moles Pollution regulations in the United States typically reference their pollutant limits to an ambient temperature of 20 to 25 °C as noted above.
