Product Functions of Superheater and Reheater
Superheater
  • In a thermal power plant, the superheater's job is crucial. It gets rid of the remaining 1 to 2% moisture in the saturated steam leaving the boiler and cranks up its temperature way above the saturation point. This makes the steam more powerful and efficient.
  • Superheating boosts the overall efficiency of the power generation cycle and prevents excessive condensation in the turbine's final stages, protecting turbine blades from damage.
  • The superheater uses heat from the furnace's combustion gases to dry out the steam completely and then superheats it for efficient power production.
  • Designed with multiple tube circuits running side by side, featuring return bends and headers for even steam distribution and maximum heat transfer.
Reheater
  • Reheaters reheat steam that's already expanded in the turbine, maintaining steam dryness through the turbine's last stage for better performance and less component wear.
  • Located in utility boilers, typically before or after the convective superheater. Modern high-pressure boilers feature two-part reheaters.
  • The primary section starts reheating in the convective zone, while the secondary section at the furnace exit brings steam to optimal temperature.
  • Designed similarly to superheaters for high-temperature operation and efficient heat transfer.
  • While output temperatures match superheaters, reheaters operate at only 20-25% of superheater pressure, allowing cost-effective use of lower-grade steel alloys.
Manufacturing and acceptance criteria of Superheater and Reheater
  1. JB/T1611 "Technical specification for manufacturing of boiler pipes."
  2. JB/T1612 "Boiler pressure test technical conditions."
  3. JB/T1613 "Technical specification for welding of pressure parts of boiler."
  4. JB/T1615 "Technical specification for painting and packing of boiler."
  5. JB/T3375 "Rules for receiving acceptance of materials for boiler construction."
Details of Superheater and Reheater
Material composition Carbon steel, alloy steel or heat-resistant steel, collection boxes and other supporting material. Tubes are customized types of specifications.
Design pattern Vertical or horizontal layout.
Advantages Beautiful appearance, size accuracy, first-class bending and welding technology, first-class detection equipment.
Type Comparison
Pendant-type
  • Firm structural support
  • Flow blockage by condensed steam
  • Needs slow restart to purge accumulated water
  • Supported from above
Inverted-type
  • Proper drainage of condensed steam
  • Lacks structural rigidity in high speed gas flow
  • Supported from below
Horizontal-type
  • Proper drainage
  • Good structural rigidity
  • Mainly convective type, not viewing flame directly
  • Supported in vertical gas ducts parallel to main furnace
