## Stack Design Pressure Draft for Furnace Solution

STEP 0: Pre-Calculation Summary
Formula Used
Draft Pressure = 0.0342*(Stack Height)*Atmospheric Pressure*(1/Ambient Temperature-1/Flue Gas Temperature)
PDraft = 0.0342*(Ls)*PAtm*(1/TAmbient-1/TFlue Gas)
This formula uses 5 Variables
Variables Used
Draft Pressure - (Measured in Meter) - Draft pressure, also known as chimney draft or flue draft, refers to the pressure difference between the inside and outside of a combustion system or chimney.
Stack Height - (Measured in Meter) - Stack Height is the height of chimney/ furnace which is used to vent the combustion gases and emissions produced during heating/combustion.
Atmospheric Pressure - (Measured in Pascal) - Atmospheric Pressure is the pressure exerted by the atmosphere on to the surface of Earth.
Ambient Temperature - (Measured in Kelvin) - Ambient Temperature refers to the temperature of the surrounding air or environment at a specific location.
Flue Gas Temperature - (Measured in Kelvin) - Flue gas temperature refers to the temperature of the gases that are produced as a byproduct of combustion in various processes, such as in industrial furnaces.
STEP 1: Convert Input(s) to Base Unit
Stack Height: 6500 Millimeter --> 6.5 Meter (Check conversion ​here)
Atmospheric Pressure: 100000 Pascal --> 100000 Pascal No Conversion Required
Ambient Temperature: 298.15 Kelvin --> 298.15 Kelvin No Conversion Required
Flue Gas Temperature: 350 Kelvin --> 350 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
PDraft = 0.0342*(Ls)*PAtm*(1/TAmbient-1/TFlue Gas) --> 0.0342*(6.5)*100000*(1/298.15-1/350)
Evaluating ... ...
PDraft = 11.0454996286625
STEP 3: Convert Result to Output's Unit
11.0454996286625 Meter -->11045.4996286625 Millimeter (Check conversion ​here)
11045.4996286625 11045.5 Millimeter <-- Draft Pressure

## What is Pressure Draft in Furnace?

In the context of a furnace, Pressure Draft (also known as forced draft or positive pressure draft) is a method used to create a controlled flow of air or combustion gases within the furnace system. The pressure draft is achieved by using mechanical means, such as fans or blowers, to force air into the furnace and maintain a positive pressure inside the combustion chamber.

## What is Significance of Pressure Draft in Furnace?

In a pressure draft system, the air is pushed into the furnace, ensuring that the pressure inside the combustion chamber is higher than the atmospheric pressure outside. This positive pressure helps to prevent any leakage of combustion gases and ensures that the flames and combustion process remain contained within the furnace.

## How to Calculate Stack Design Pressure Draft for Furnace?

Stack Design Pressure Draft for Furnace calculator uses Draft Pressure = 0.0342*(Stack Height)*Atmospheric Pressure*(1/Ambient Temperature-1/Flue Gas Temperature) to calculate the Draft Pressure, The Stack Design Pressure Draft for Furnace formula is defined as pressure inside the combustion chamber/ furnace during operations. This pressure ensures that the flames and combustion process remain contained within the furnace. Draft Pressure is denoted by PDraft symbol.

How to calculate Stack Design Pressure Draft for Furnace using this online calculator? To use this online calculator for Stack Design Pressure Draft for Furnace, enter Stack Height (Ls), Atmospheric Pressure (PAtm), Ambient Temperature (TAmbient) & Flue Gas Temperature (TFlue Gas) and hit the calculate button.
