Forced Draught Air Cooled Heat Exchanger API 661 For Petroleum Industry
Forced Draught Air Cooled Heat Exchanger with API 661, Petroleum Industry
Selection of Induced Draught or Forced Draught
The air-cooled heat exchanger shall be either a forced-draught exchanger or an induced-draught exchanger and shall include the components shown in Figure 1 and any auxiliaries such as ladders, walkways and platforms. Forced-draught fans should be used, except that induced-draught fans should be considered for the following situations:
If temperature control of the process is critical and sudden downpour of rain (i.e. excessive cooling) can cause operating problems
To minimize the risk of hot-air recirculation
On sites where air-side fouling is a significant problem, however forced draft can be used if screens are specified
To improve thermal performance in the event of a fan failure (due to the stack effect)
In hot climates, where the fan plenum chamber shields the bundle from the sun
For services that have a temperature approach of 11 °C (20 °F) or less
