which parts of boiler are called heating surface?..

Answer / magesh

I feel that the question is wrong. In Boiler there are no
such specific Heating Parts, where as all are called as HEAT
TRANSFER PARTS, which includes
1. Furnace(Nothing but a closed area sorrounded by waterwalls.)
2. SuperHeaters(Tube coils, which further increase the
temperature of the steam say around more than 500 deg.c.)
3. Bed Coils(Placed at very closer to the heating area)
4. Economiser (Can Preheat water at 150 DEG C)
5. Evaporator Coils(Mostly used in Waste Heat Recovery
Boilers, where there are no bed coils)

Answer / santosh raikar

all the surface which is exposed to flue gas/ flue gas path,
only condition is that heat transfer takes place between
feed water/ steam and flue gases. flue gas ducting is not
considered as heating surface even thought it is exposed to
flue gases.
in simple terms the surface helpful to transfer combustion
heat to water/steam
