Description

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:


  • a) If temperature control of the process is critical and sudden downpour of rain (i.e. excessive cooling) can cause operating problems;
  • b) To minimize the risk of hot-air recirculation;
  • c) On sites where air-side fouling is a significant problem, however forced draft can be used if screens are specified;
  • d) To improve thermal performance in the event of a fan failure (due to the stack effect);
  • e) In hot climates, where the fan plenum chamber shields the bundle from the sun;
  • f ) For services that have a temperature approach of 11 °C (20 °F) or less
