Key Applications of Rosewool Ceramic Fiber Boards
Rosewool’s boards are trusted in some of the harshest industrial environments:
1. Power Generation
- Boiler Systems: Insulate steam pipes, economizers, and superheaters in coal, gas, or biomass-fired plants to reduce heat loss by 70–90%.
- HRSG (Heat Recovery Steam Generators): Line exhaust ducts to recover waste heat and boost turbine efficiency.
2. Oil & Gas & Chemical Processing
- Pipeline Insulation: Protect high-pressure pipes carrying hot crude oil (150–300°C) or natural gas in offshore rigs from thermal loss and corrosion.
- Reactor Vessels: Insulate lines with corrosive fluids (e.g., sulfuric acid, ammonia) while preventing CUI (Corrosion Under Insulation).
3. Metal Processing
- Annealing Ovens: Maintain consistent temperatures in heat-treatment chambers for steel and aluminum to ensure material integrity.
- Foundries: Line casting molds or ladles to retain molten metal temperatures and reduce energy use.
4. Renewable Energy
- Biomass Boilers: Insulate high-temp exhaust systems in bioenergy plants to improve combustion efficiency.
- Concentrated Solar Power (CSP): Line receiver tubes to retain thermal energy, boosting electricity output.
