Rosewool Insulation Refractory Co.,Ltd.
Recently, Rosewool Insulation Refractory Co.,Ltd.’s ceramic fiber blanket PLUS blanket was successfully delivered to the construction site of the power plant, and the unloading operation was completed in an orderly manner. This batch of high-performance fire-resistant insulation materials is about to be put into the unit overhaul insulation construction. Customer feedback on site indicates that Rosewool Insulation Refractory Co.,Ltd. ceramic fiber blanket was used in the early stage of the project, which has excellent thermal insulation performance and effective control of equipment heat dissipation. We actively recommended to our industry partners to cooperate with our company on insulation materials.
The boilers and flue gas systems in thermal power plants have been operating at high temperatures for a long time, with frequent start-up and shutdown of the units and significant temperature fluctuations. The boiler body, high-temperature flue, hot air duct, denitration inlet and outlet flue, turbine cylinder body, high-temperature header, manhole door, expansion joint and other key parts require strict requirements for refractory insulation materials. If the performance of the insulation layer is insufficient, it will cause a large amount of heat loss, increase the consumption of plant electricity and coal, pose safety hazards due to high equipment shell temperature, accelerate steel structure corrosion, and shorten equipment maintenance cycle. Therefore, the selection of insulation for high temperature sections is directly related to energy conservation, consumption reduction, and safe production of power plants.
PIUS blanket is a new type of insulation blanket specifically designed for steam turbines launched by Rosewool Insulation Refractory Co.,Ltd. to power plant customers. It is made from selected hot materials such as coke gemstones, which are melted at high temperatures, blown into fibers, solidified, and cut and rolled. It has the characteristics of high temperature resistance, good stability, high chemical stability, low thermal conductivity, low heat capacity, and easy cutting and construction. Compared with natural aluminum silicate needle punched blanket, it has lower slag ball content, higher tensile strength, better rebound rate, no burrs in cutting, convenient construction, better insulation effect, and longer service life. Rosewool Insulation Refractory Co.,Ltd. PLUS carpet slag ball content is less than 5%, with a tensile strength far exceeding 110KPA;
The reason why ceramic fiber blanket PLUS blanket has become the core insulation material for high temperature conditions in power plants is due to its outstanding comprehensive performance. At power plant sites, ceramic fiber blankets are widely used in boiler walls, roofs, superheaters, reheaters, high-temperature flues, primary and secondary air hot air ducts, denitrification systems, turbine cylinders, expansion joints, manhole doors, and various shaped high-temperature equipment. They are mostly used as composite insulation inner layers. It has a high temperature resistance level and can withstand high temperature impacts of equipment for a long time. It has outstanding thermal shock resistance and is not easily prone to pulverization, cracking, or detachment failure in the face of sudden temperature changes caused by unit start-up and shutdown. It is suitable for on-site environments with large vibrations and frequent fluctuations in operating conditions in power plants.
The material has a low thermal conductivity and strong insulation and heat resistance effect, which can effectively lock in the internal heat of the equipment, reduce the heat dissipation loss on the outer wall of the equipment, improve the thermal efficiency of the unit, and help power plants achieve cost reduction and energy conservation. The product is flexible in texture and can be cut freely. Pipes, cylindrical flues, and shaped equipment can be tightly wrapped and fitted, making construction convenient and efficient; Lightweight and lightweight, it will not add additional load to the steel structure and reduce the frequency of maintenance and replacement in the later stage.
Rosewool Insulation Refractory Co.,Ltd. is deeply engaged in the field of high-temperature insulation in the power industry. It produces adaptive ceramic fiber blankets for complex flue gas and high-temperature vibration conditions in power plants. The products have uniform bulk density, resistance to flue gas erosion, and stable and reliable quality. From production, loading and transportation to on-site supply and delivery, the entire process ensures the construction progress of the power plant overhaul project. Gain recognition and referral from power customers with excellent product strength. In the future, Rosewool Insulation Refractory Co.,Ltd. will continue to polish high-temperature insulation products, providing reliable industrial insulation solutions for major power plants and metallurgical enterprises, and safeguarding the safe and efficient operation of high-temperature equipment.
