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:

• 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
