Jan 01, 2013 · Lurgi CFB boilers used an external heat exchanger (FBHE), whereas Foster Wheeler CFB (before 1994) did not. The differences between these two systems can be seen in Fig. 16.3. Lurgi CFB boilers use a CFB loop with an external heat exchanger (FBHE) where about 20–60% of the total heat (excluding the boiler back pass) is absorbed.
