Chimney or Flue Size (Height) A height of 4.5 meters is recommended as a minimum height for a chimney stack or flue although other factors need to be taken into consideration such as the roof height, adjacent buildings, roof windows and the material the roof is constructed from.
Combustion of Fossil fuel/Bio-fuel in Boilers is one of the proven methods for production of steam, required for the process in various types of industry. The running of Boiler with fuels of proper specification at a higher efficiency is the key to reduce the SOx, NOx& the PM levels in the stack which are the key air pollutants.

The temperature is expected to be about 75 degc. Prior to sea water scrubbing of the flue gas, the temperature of the flue gas is 400 deg c and the stack height is about 150 metres. With lower temperature after the scrubber project, can we route the flue gas into existing stack of 150 m. If not what is the max height that the new stac
CHIMNEYS AND DRAFT. The height and diameter of a properly designed chimney depend upon the amount of fuel to be burned, its nature, the design of the flue, with its arrangement relative to the boiler or boilers, and the altitude of the plant above sea level.
Nevertheless, the stack height determined by the Memorandum will normally be sufficient for condensing boilers with low NOx burners (<0.02g/MJ) with thermal input less than 1 MW burning very low
Chimney effect = 353 x Chimney Height x [1/ Stack gas temperature – 1/ Ambient Temperature] Where . Chimney effect is in mm of water column. Chimney height is in mteres. Temperatures are in ° Kelvin. For a thermal power plant with a stack height of 250 meters the effect could be around 77 mm of water column.
PROBLEM #3: CHIMNEY HEIGHT. The additional height added to the chimney is proportional to the increase in draft. For example, if a chimney height is increased by 2 feet and the chimney is 10 feet high, the effective improvement is 20%. On the other hand, the same 2 feet added to a chimney that is 30 feet high is only 7%.
Calculate the air flow caused by natural draft in a normal family house with two floors. The height of the hot air column from ground floor to outlet air duct above roof is approximately 8 m. The outside temperature is -10 o C and the inside temperature is 20 o C. A duct of diameter 0.2 m goes from 1. floor to the outlet above the roof.
The velocity of air and flue gas in a smaller furnace should not exceed 2 m/s. Design velocities of larger furnaces should not exceed 10 m/s. Required chimney area can be calculated as A = Q / v (3)
chimney height calculation methodologies are investigated for five European countries by calculating the chimney height for some specifically created case studies following the different models, with the purpose of carrying out a comparison and to understand the differences existing in chimney height calculation.
Calculate Flue Gas Stack Height. Say it is X kg. Per hour. - Find out the percentage of sulphur content in the diesel you are using. Say it is P%. - Now, you have to calculate the sulphur dioxide (SO2) percentage in flue gas. Since the atomic weight of SO2 is double the atomic weight of sulphur, the percentage of the SO2 in flue gas is 2P %.
The median stack height for all 108,590 stacks from AFS and NET is 10.67 m (35.0 ft). This median stack height of 10.67 m for stacks should not be confused with the median height of 9.14 m for all TRI facilities, which is based on AFS, NET, and State data, as described in Section 6.3.
A chimney provides draft for suction of air into the cookstove, and to remove flue gases from the kitchen. While draft directly depends on chimney height, a larger diameter results in greater mass inflow of air due to a larger area and a reduced frictional pressure drop through the chimney.
Height of chimney 2.44 m Volume of CO2 produced during burning 0.64 m^3 Gravity 9.81 m/sec^2 Mass of O2 need to burn carbon 964.17 32.00 g Draft of chimney 10.93 Pascals Moles of O2 needed to burn carbon 30.13 1.05 moles Volume of O2 needed to burn carbon 0.67 m^3 Volume of air needed to supply the above O2 (273) 3.21 m^3 or/and Mass of H2O vapor created in burning 361.57
The clever design of the chimney for the gas boiler and its competent installation is an important component of efficient heating in a private house. There are unacceptable mistakes, otherwise there will be insufficient traction, costs will increase, and the outflow of combustion products will be incomplete.
For more simplified calculation, Table 3 can be used to determine theoretical draft assuming the density of chimney gas is the same as that of air, the barometric pressure is at sea level and the ambient temperature is 60ºF.

Apr 29, 2018 · It depends on SO2 concentration in flue gas and amount of fuel consumed by that Steam Generator. Height if chimney(in meters) = 14(Q)^0.3 Q= ( Fuel quantity(kg/hr)*SO2 content(%)*2)/100
DG set stack, flue gas stack, process stack, furnace stack, boiler stack, chimney etc. CPCB guidelines for Stack Height Chimney, Boiler, DG set, DG exhaust pipe etc. Stack height calculation plays an important role in determination of dispersion of pollutants in upper level of air relevant to local building height.
the ratio of the diameter of the chimney to the section of the branch pipe of the gas boiler, which is checked when buying a boiler and chimney; The height of the chimney must be greater than the top of the roof - to ensure traction in any direction of the wind; External (external) chimney must be insulated from the outside;
Sep 08, 2011 · There is no solid rule to chimney length. My Dad has a stove in his workshop, chimney is about 20 ft total length (2 story building). He had to put 2 dampers on teh stove pipe because there is that much draft with that chimney. Can't even light the stove with teh drafts open because the match will go out.
Less than GEP stack height. GEP stack height is 675 feet based on a building height of 270 feet and a building width of 502 feet. Minimum flowrate and velocity used for "worst case" Class II impact. Maximum flowrate and velocity used for "worst case" Class I impact.
The basic cube here is 100 ft x 100 ft x 100 ft. Thus, the dimension H is equal to 100 ft. The top of the eddy is 0.5H above the roof, thus for this building a chimney 0.5 (100 ft) = 50 ft high above the roof is necessary to be above the eddy currents.
The Chimney Heights Memorandum may be used for boilers with thermal inputs between 150 kW and 366.4 kW and this is generally considered to be good practice. It is unlikely that individual boilers with thermal inputs less than 366.4 kW will lead to exceedences of the air quality objectives over any significant area.
Chimney or Stack Effect is a natural phenomena that is very common in the fireplaces in homes, tall skyscrapers and power plant flue gas stacks. The natural phenomena of the density difference between a hot and cold air column that creates a natural flow through a chimney is called the Chimney effect.
