2.1 The role of traffic

Traffic has two main objectives:

  • ensure the proper cooling of tubes located in the hottest areas or exposed to the direct radiation of the fire, and which receive the maximum heat flux at this point;

  • ensure saturated steam generation, i.e. the transition of the heated fluid from the water state to the emulsion and steam state (excluding supercritical pressure boilers, where the fluid conveyed is simply heated).
