boil water flowing over the tubes. At the time of instal-                                  lation,   the   overall   heat   transfer   coefficient     was

 

400 W/m2 · K. After 1 year of use, the inner and   outer

Tm,i

= 75°C

 

tube surfaces are fouled, with corresponding fouling factors of Rƒ",i 0.0015 and Rƒ",o 0.0005 m2 · K/W, respectively. Should the boiler be scheduled for clean- ing of the tube surfaces?
