COILS

PP Boilers specializes in the design, fabrication, and supply of high-performance boiler coils engineered to meet the demanding thermal and mechanical requirements of modern industrial boilers. Our range includes Studded In-Bed Coils, Economizer Coils, and Superheater Coils, each tailored for specific zones within the boiler system to maximize heat transfer, reliability, and efficiency.

Studded In-Bed Coils : Boiler Bed Coils (Fluidized Bed Coils / Bed Evaporators)
Studded In-Bed Coils are critical heat transfer elements embedded within the fluidized bed of AFBC boilers. Designed to operate under high-temperature, high-erosion environments, these coils efficiently extract heat from combusting bed material and transfer it to the working fluid (water/steam). Their studded surface significantly increases the effective heat transfer area and sustains fluidization within the bed.

Design & Construction:

  • Constructed from high-grade materials including ASTM A106 Gr. B, A192, SA 210 Gr. C, and stainless steels like SS 304/316
  • Tube OD: 25 to 63.5 mm, with wall thicknesses optimized for high-pressure service
  • Studs/Fins: Welded MS or SS304 studs to improve heat transfer and protect against erosion
  • Surface-treated for resistance to corrosion, erosion, and scaling


Functions:

  • Absorbs direct heat from hot bed material to produce saturated steam
  • Promotes stable fluidization essential for efficient combustion
  • Helps maintain uniform bed temperature, improving thermal efficiency and combustion control
  • Enhances boiler responsiveness during fluctuating load conditions


Performance & Advantages:

  • Engineered for long service life under abrasive and cyclic thermal loads
  • High thermal conductivity and mechanical strength ensure reliable operation
  • Custom-designed for specific boiler capacities and fuel types
  • Supports rapid steam generation and efficient load response
  • Compliant with ASME Section I, IBR, and client-specific requirements
