After the evaporative tubes, the steam-water mixture enters the boiler superheater
. Further, the superheated steam along the steam line is directed to the impellers of the steam turbine.
Based on the parabolic law of high-temperature oxidation, Arrhenius equation, and related basic theories of heat transfer, an oxide scale growth model of boiler superheater
tubes is proposed through iterative technique .
Contract Awarded for Uss Frank Cable No2 Boiler Superheater
During introduction of sonic cleaning at that boiler superheater
, five test series with duration of 15-25 days were performed.
The particles in question are solid iron oxides, mostly magnetite, that form on the surfaces of boiler superheater
, reheater, and steam piping.
The boiler superheater
and evaporator as well as the latest transmission pipelines.
The probes were designed as waterfilled heat pipes whose working (heat-absorbing) surfaces (with outer diameter of 35 mm) have temperatures on the level of the corresponding surface temperature of an actual boiler superheater
(up to 550 [degrees]C) or economizer (300-350 [degrees]C).
Even pinhole leaks can cause damage to adjascent tubes, especially in the boiler superheater
and reheater sections.
The effect of other factors (steel preparation, tube manufacturing technology, etc.) could not be, unfortunately, predicted with satisfactory accuracy, so each new steel should be tested in conditions similar to oil shale boiler before making final conclusion about its convenience for oil shale boiler superheater
Terms of Service - HHM K2, K1 boiler superheater
coils manufacturing and installation and replacement of superheater presentation, 6 superheater coil unit replacement.
During these survey periods boiler Superheaters
are replaced, a comprehensive NDT programme is undertaken and boiler tubes replaced as necessary; boiler mountings are removed and overhauled prior to surveyor~s inspection; the grate upon which the refuse is burned is overhauled; Auxiliary plant associated with the boilers is overhauled including maintenance of electrostatic precipitators.
