Product Description

MYREAL boiler insulation board uses the MY220 grade: up to 220 kg/m3, compressive strength of 0.65 MPa and conductivity of 0.087 W/(m.K) at 300 C. The board holds thickness on curved boiler shells and drums, resists burner and fan vibration, and keeps the casing surface temperature within design limits so boiler thermal efficiency is maintained.

Application

Applied to boiler shells, drums, headers and connecting pipework in steam and hot water boiler plants.

  • Steam boiler shell and drum insulation
  • Hot water boiler body insulation
  • Boiler header and downcomer insulation
  • Economiser and air preheater casing insulation
  • Boiler house pipework and manifold insulation

Key Advantages

  • MY220 grade with 0.65 MPa compressive strength resists vibration and handling.
  • 0.087 W/(m.K) at 300 C keeps casing surface temperature within design limits.
  • Rigid board holds thickness on curved shells without compression points.
  • Class A1 non-combustible for boiler house fire safety.
  • Low water absorption, performance is not affected by humidity.

Standards and Compliance

  • Manufactured to GB/T 5486 calcium silicate products standard under an ISO 9001 certified quality system
  • GB/T 8624 Class A1 non-combustible, no flame spread and no dense smoke
  • Super low chloride ion content protects stainless steel and alloy pipework from chloride stress corrosion
  • Low water absorption, performance is not affected by humidity
  • Free of formaldehyde, benzene and other harmful substances
  • Special shaped parts can be customized to your drawing

Installation Notes

  • Kerf-cut the board to follow drum and shell curvature.
  • Band the board in place with stainless steel strapping at 300 mm centres.
  • Apply two layers with staggered joints on high surface temperature areas.
  • Finish with aluminum cladding or a cement based coating.

FAQ

Q: Can the board be curved?
A: Yes. Kerf cutting the back face allows the board to follow drum and header curvature.
Q: What thickness suits a boiler shell?
A: Typically 50-80 mm, selected from the shell temperature and the required casing surface temperature.
Q: Is it suitable outdoors?
A: Yes when finished with aluminum cladding or a weatherproof coating.
