High-temperature calcium silicate insulation engineered for power plant boilers, steam pipes, turbine housings, economizers, and flue gas ducts. Maximum energy efficiency, reduced heat loss, and reliable long-term thermal protection.
Power generation facilities — including coal-fired, gas-fired, biomass, and waste-to-energy plants — operate with steam temperatures reaching 600°C and combustion chambers exceeding 1000°C. Efficient thermal insulation is essential to minimize heat losses, maximize turbine efficiency, and protect personnel from hot surfaces.
HR RHINO calcium silicate boards deliver exceptional thermal performance across the entire power plant system — from boiler walls and superheater sections to steam pipes, turbine casings, and flue gas ducts. Our products reduce energy loss, lower fuel consumption, and extend equipment service life.
Based on xonotlite (6CaO·6SiO₂·H₂O), our boards provide low thermal conductivity, vibration resistance, excellent dimensional stability under thermal cycling, and long-term reliability — making them the preferred insulation solution for modern power stations worldwide.
Six critical power generation system components where HR RHINO calcium silicate boards deliver superior thermal insulation and energy savings.
Boiler walls and combustion chambers require high-temperature insulation to contain heat, improve thermal efficiency, and protect structural steel. Our boards work behind refractory linings as reliable backup insulation.
High-pressure steam pipes transporting steam from boilers to turbines operate at 400-600°C. Calcium silicate insulation minimizes heat loss, ensures energy efficiency, and protects personnel from hot surfaces.
Superheater and reheater sections transfer heat to steam at 500-600°C. Our boards insulate headers, tube supports, and surrounding structures to maintain optimal steam temperature.
Economizers recover heat from flue gases to preheat feedwater. Calcium silicate boards insulate economizer casings, maintaining surface temperatures within safe limits while maximizing heat recovery.
Flue gas ducts, dampers, and stack liners require thermal insulation to prevent heat loss, control acid gas condensation, and protect steel from thermal stress. Our lightweight boards are ideal for these applications.
Steam turbine casings, main steam valves, and control valves operate at 400-600°C. Our custom-shaped insulation blocks maintain efficiency and provide removable insulation for maintenance access.
Engineered to maximize thermal efficiency and reliability in power generation applications.
Low thermal conductivity significantly reduces heat loss from boilers and steam pipes, improving overall plant efficiency and reducing fuel consumption.
Excellent mechanical strength handles continuous vibration from turbines, fans, and large rotating equipment without crumbling or settling.
Stable under repeated startup/shutdown cycles. Linear shrinkage <1.5% at 1000°C maintains insulation integrity over decades of service.
