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

1 Answers DRDO,

My vendor filled liquid oxygen in our 11000 liter capacity tank. He filled from 1400 MMWC up to 3200 MMWC. I followed the provided conversion table and found that we had been supplied 1800 MMWC liquid which is going to yield 2815 cubic meter. On the other hand, the vendor claims that he supplied as follows:- 5236 cub mtr(3200 MMWC)-2124 cub mtr(1400MMWC) = 3112 cub mtr. I fear that he wants to charge 297 cubic meters extra. He claims that my method was wrong and his was right. He says that this disparity is because of the conical shape of the base of the flask. I will be thankful if somebody can explain me the truth.
