FURNACE:
_=:
F-301 Fractionator Crude Heater
:
Note: If the tubes are in satisfactory condition no change is
required, as the furnace is presently over alloyed. However,
if a change is warranted the following criteria shall hold.
Convection Section Tubes - c.s.
Radiation Section Tubes - c.s. w/ 1/8" c.a. except for the
20 outlet tubes to be 5 Cr w/ .05" c.a.
Headers - selected to match tube material
Tube Support Castings - Up to 1000F Cast Iron
- 1000F - 1200F Cr - Ni Cast Iron
Note: Carbon Steel and Chrome Steel tubes are based on the following
corrosion allowances for operating Stock Temperatures:
Stock Temp. F
c.a. in inches
Carbon Steel 500"
0.1
550 0.32
% Chrome Stl 500
0.05
550 0.15
Note:
If furnace fuel will contain Vanadium, design for
a maximum 1200F tube support temp.
Corrosion allowance based on an anticipated
life of 10 years.
