Natural Draft: This is the most common design for fired heaters, which does not require a fan to generate airflow. In this method, the lower density of gases inside the heater compared to the surrounding air creates buoyant forces that drive the flow from bottom to top. This phenomenon, also known as the stack effect, draws air in from the bottom (the burner inlet) and expels combustion products through the stack outlet, the highest point of the fire heater. The intensity of the airflow is dependent on the temperature of the gases inside the heater and its height.
Forced Draft: In this method, air is drawn from the surroundings using a fan and directed into the burner inlet. The fan used in this system is called the FD fan (Forced Draft fan).
Induced Draft: In fired heaters with induced draft, a fan draws air from the outlet of the heater and vents it into the atmosphere. The fan used in this case is called an ID fan.
Balanced Draft: In these fired heaters, an FD fan is located at the inlet and an ID fan at the outlet, with both fans assisting in the movement of gas and air through the heater.
