Enter the fuel consumption rate and the sulfur content into the calculator to determine the required chimney height. This calculator helps to estimate the minimum chimney height to ensure proper dispersion of sulfur dioxide emissions.

Chimney Height Formula

The following formula is used to calculate the chimney height.

H = 14 + (5.5 * √(FR * (SC / 100)))

Variables:

  • H is the chimney height (meters)
  • FR is the fuel consumption rate (kg/hour)
  • SC is the sulfur content (%)

To calculate the chimney height, add 14 to the product of 5.5 and the square root of the fuel consumption rate multiplied by the sulfur content percentage divided by 100.

What is Chimney Height?

Chimney height is the vertical distance from the base of a chimney to its top. It is an important design parameter that affects the dispersion of pollutants in the atmosphere. The height of a chimney is determined based on several factors, including the type of fuel used, the rate of fuel consumption, the sulfur content of the fuel, and local environmental regulations. Proper chimney height is crucial for minimizing the impact of emissions on air quality and ensuring compliance with environmental standards.

How to Calculate Chimney Height?

The following steps outline how to calculate the Chimney Height.


  1. First, determine the fuel consumption rate (FR) in kilograms per hour.
  2. Next, determine the sulfur content (SC) of the fuel as a percentage.
  3. Use the formula H = 14 + (5.5 * √(FR * (SC / 100))) to calculate the chimney height (H) in meters.
  4. Finally, calculate the Chimney Height (H).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Fuel consumption rate (FR) = 200 kg/hour

Sulfur content (SC) = 3%\
