Combined Cycle (CCPP) and Thermal Power Plant Insulation

POWER PLANT INSULATION SYSTEMS

Professional Solutions in Combined Cycle (CCPP) and Thermal Power Plant Insulation

Power plants are among the industry's most complex facilities, managing high temperatures, pressure, vibration, and challenging process conditions simultaneously. Therefore, proper insulation applications for all pipelines, turbines, boilers, HRSG (Heat Recovery Steam Generator) systems, auxiliary equipment, and process units within the plant are critically important for facility efficiency, energy savings, personnel safety, and operational continuity.

As ERATHERM, we are one of Turkey and Europe's leading power plant insulation companies. With over 40 years of experience, we have executed projects with a total installed capacity exceeding 15,000 MW. We offer engineering, project design, feasibility analyses, material supply, scaffolding systems, and turnkey insulation applications for combined cycle (CCPP), thermal power, biomass, cogeneration, and trigeneration plants.

⭐ 1. The Critical Role of Insulation in Power Plants

Insulation in power generation facilities is not limited to reducing heat loss. Insulation that is poorly designed or implemented with unsuitable materials:

Creates high energy losses,
Disrupts process balance,
Increases maintenance costs,
Puts worker safety at risk,
Causes corrosion and mechanical deformation in equipment.
Therefore, insulation in power plants should be addressed not merely as an application but as a multi-disciplinary engineering process.

ERATHERM designs insulation systems that deliver optimal performance using world-standard engineering principles in all its projects.

⭐ 4. Combined Cycle Power Plant (CCPP) Insulation

Combined cycle power plants are highly efficient facilities where gas and steam turbines operate within the same process. Therefore, insulation applications involve challenges such as:

High temperatures,
High vibration,
Continuous load variations.
ERATHERM specializes in the following areas for CCPP insulation:

✓ Gas turbine insulation (Hot casing insulation, Exhaust diffuser insulation, Compressor outlet lines, Expansion joints)
✓ HRSG (Heat Recovery Steam Generator) insulation (Economizer, Evaporator, Superheater lines, Stacks / chimneys)
✓ Steam turbine insulation (Insulation jacket systems, Spray + jacket combination systems, High-temperature applications)
✓ Auxiliary facility insulation (BOP lines, Fuel gas systems, Lubrication systems, Fire protection lines, Cooling water circuits)

⭐ 5. Thermal Power Plant Insulation

Insulation in thermal power plants covers processes involving very high temperatures, such as:

Boiler bodies
Mills / Grinders
Electrostatic precipitators
Flue gas lines
Economizers and heat exchangers
Ash handling systems
In such facilities, material selection and application details are the most critical factors determining plant lifespan.

In thermal power plant insulation, ERATHERM produces the most reliable solutions with:

Special insulation techniques for environments up to 600°C,
High-density rockwool,
Ceramic fiber insulation,
Special cladding engineering.
