The dimension of the pipe:
Outside diameter = 325mm
Inside diameter = 350mm
Wall thickness = 150mm
Physical properties
Outer surface temperature = 576 degreeC
Inner surface temperature = 350...
Dear all,
Can anyone provide some information about the water quality inside a boiler of a CCGT facility. Any good books and standards (British standard, German Standard....) refer to this area.
What are the general parameters which defined the water quality? e.g. Oxygen content, pH, Silica...
