hI EVERYONE
THAT'S MY QUESTION:
"MAX FASE VELOCITY" FOR AIR PREHEATER IS THE SAME OF AIR COOLER (ABOUT 600 FPM)?

I THINK NO, BECAUSE AIR MOISTURE DOES NOT CONDENCE.

 

[r0b3rt0p]

sORRY FOR MY LAST SENTENCE,
INFACT, AIR COOLER RISE AIR TEMPERATURE ALSO,
SO MAYBE AIR PREHEATER NEEDS MAX 600 FPM (FACE VELOCITY).

CAN YOU EXPLAIN WHY MOINSTURE CARRYOVER IS A PROBLEM?
