Steam turbines operate under extreme thermal conditions, reaching temperatures of up to 600°C. While this is inherent to their nature, leaving a turbine uninsulated can lead to critical consequences: internal mechanical damage, personnel hazards, deterioration of wiring and sensors, and a drastic reduction in equipment lifespan. In this article, we explain why thermal insulation is a necessity, not an option.

Mechanical Damage: The Invisible Enemy

Turbines are designed to operate within a specific thermal range. Without insulation, heat dissipates uncontrollably, and sudden temperature changes can cause expansion and contraction in metal components. This generates thermal fatigue, which results in microfractures, misalignment, structural failures, and even unscheduled shutdowns.

Without insulation, the turbine works harder, heats up more, and breaks down faster.

Extreme temperatures = risk to personnel

An uninsulated turbine can reach surface temperatures exceeding 600°C. This poses a direct danger to operators working near the equipment. Simple contact with a hot surface can cause second- or third-degree burns. Furthermore, the high temperatures increase the ambient heat, hindering safe operation and maintenance.

With proper thermal insulation, the surface temperature can be reduced to below 60°C, making it safe to touch.

Heat also damages technology

Electrical wiring, control sensors, electronic boards, and connections near the turbine are not designed to withstand direct exposure to extreme heat. Without insulation, constant thermal radiation accelerates wear, causes intermittent or permanent failures, and can even lead to fires due to melting coatings.

A temperature sensor can give inaccurate readings if the area is overheated, causing problems with automation or the safety system.

Abrupt thermal changes: direct impact on lifespan

Turbine switching on and off causes temperature spikes. Without insulation to regulate heat dissipation, these spikes directly affect the casing, bearings, and coupling system. Over time, this leads to accelerated wear, loss of efficiency, and the need for premature replacements.

Insulation acts as a thermal stabilizer, preventing the turbine from suffering damaging thermal shocks.

Thermal insulation: an investment that protects

Investing in removable insulation not only improves energy efficiency. It provides a comprehensive layer of protection for the turbine, its electronic components, and personnel. Furthermore, its removable nature allows for maintenance without damaging the insulation system, extending the equipment's lifespan.
