As the core site of energy production, power plants have key equipment such as boilers, steam turbines, and thermal pipelines that operate at high temperatures and pressures for a long time. The insulation and fire resistance protection directly affect the operational efficiency, energy loss, and production safety of the units. Among numerous insulation and refractory materials, rock wool board has become the core choice for power plant insulation engineering due to its excellent functional advantages suitable for power plant scenarios. Rosewool Insulation Refractory Co.,Ltd has been deeply involved in the industry for many years. With customized power plant rock wool board products and full chain services, it provides stable protection for dozens of power plants in China and has become the preferred partner for power plant enterprise cooperation. ​
                                                                                        
The functional advantages of rock wool board insulation refractory materials in power plants accurately solve the core pain points in power plant production, and are the "invisible guardians" to ensure the stable operation of power plants. ​
  • Firstly, it has excellent high-temperature insulation performance, reducing energy loss in power plants. The flue gas temperature at the outlet of the power plant boiler can reach over 1000 ℃, and the high-temperature steam temperature transported by the thermal pipeline exceeds 400 ℃. If the insulation is improper, heat loss will directly lead to a decrease in power generation efficiency and an increase in coal or fuel consumption. The power plant specific rock wool board produced by Rosewool Insulation Refractory Co.,Ltd is made of high-quality basalt as raw material, which is subjected to high-temperature melting and fibrosis treatment to form a unique porous fiber structure. The thermal conductivity is as low as 0.032W/(m · K), which can effectively block high-temperature transmission. After using Rosewool Insulation Refractory Co.,Ltd rock wool board for insulation renovation of boiler flue in a certain thermal power plant, the surface temperature of the flue decreased from 120 ℃ before the renovation to below 45 ℃, reducing annual heat loss equivalent to over 2000 tons of standard coal, directly reducing power generation costs by about 1.5 million yuan, and achieving significant energy-saving effects. ​
  • Secondly, it has a high level of fire resistance and flame retardancy, which strengthens the safety defense line of the power plant. There are fire risk sources such as high-temperature equipment and flammable oil in power plants. Once a fire occurs, the consequences are unimaginable. Rock wool board itself belongs to Class A non combustible materials, which can maintain structural stability in high temperature environments of 800 ℃ -1000 ℃, without burning or releasing toxic and harmful gases, and can delay the spread of fire by forming a "thermal barrier". The rock wool board of Rosewool Insulation Refractory Co.,Ltd's power plant has been tested by the National Fire Product Quality Supervision and Inspection Center and has a fire resistance limit of more than 3 hours, far exceeding the requirements of the power plant fire protection regulations. In a certain power plant pipeline insulation project, the rock wool board successfully resisted the fire caused by local pipeline overheating, which saved critical time for equipment repair and personnel evacuation, and avoided major safety accidents. ​
  • Third, corrosion resistance, anti-aging, suitable for complex environment of power plant. During the production process of power plants, corrosive media containing sulfur and dust are generated. Long term erosion can lead to aging and damage of ordinary insulation materials, shortening their service life. According to the environmental characteristics of the power plant, Rosewool Insulation Refractory Co.,Ltd has carried out special anti-corrosion treatment on rock wool board, formed an acid and alkali resistant protective layer on the fiber surface, and added anti-aging agent at the same time, so that the service life of the product in a humid and corrosive environment can reach more than 15 years, far exceeding the industry's average service life of 8-10 years. After using this rock wool board in a coastal power plant, there has been no aging or peeling phenomenon within 5 years, significantly reducing the frequency and cost of later maintenance. ​
Choosing to cooperate with Rosewool Insulation Refractory Co.,Ltd is not only about choosing high-quality products, but also about choosing a "safe, efficient, and worry free" guarantee system for power plant enterprises. This is also the core reason why many power plants favor Rosewool Insulation Refractory Co.,Ltd. ​

From the perspective of company advantages, Rosewool Insulation Refractory Co.,Ltd has specialized research and development capabilities for power plant scenarios. The company has established a "Power Plant Insulation Material Technology Research and Development Group", in collaboration with the School of Materials Science at universities, to customize differentiated rock wool board formulas based on the temperature and medium characteristics of different types of power plants (thermal power plants, thermal power plants, nuclear power plant auxiliary facilities) to ensure product compatibility. At the same time, the company is equipped with a professional on-site survey team that can go deep into the power plant workshop, accurately measure equipment dimensions, analyze environmental parameters, provide one-stop services from material selection, scheme design to construction guidance, and avoid hidden dangers caused by mismatched materials and scenes. ​

In terms of product features, the rock wool board of Rosewool Insulation Refractory Co.,Ltd Power Plant not only has the core advantages of thermal insulation, fire resistance, and corrosion resistance, but also has the characteristics of high density and low moisture absorption. The product has a density of 120-180kg/m ³, a compact structure that is not easily deformed, and can tightly adhere to the surface of the equipment, reducing heat leakage gaps; At the same time, through special moisture-proof treatment, the moisture absorption rate is less than 5%, which can maintain stable insulation performance even in the humid water vapor environment of the power plant, avoiding a decrease in insulation effect due to moisture absorption. In addition, the product also meets the requirements of the national "Air Pollutant Emission Standards for Thermal Power Plants", with zero formaldehyde and heavy metal emissions during the production process, helping power plants achieve their green production goals. ​

Currently, the power plant industry is developing towards high efficiency and low carbonization, and the performance requirements for insulation refractory materials are constantly increasing. Rosewool Insulation Refractory Co.,Ltd, based on technology and quality, continuously optimizes the rock wool board products of power plants to ensure their safe and stable operation. Choosing Rosewool Insulation Refractory Co.,Ltd means choosing reliable partners to jointly safeguard the safety defense line of energy production and promote the high-quality development of the power plant industry.
