Application of calcium silicate board for insulation in steam turbine plant? The insulation of the steam turbine plant is divided into two parts: "insulation of the steam turbine body and high-temperature equipment pipelines in the plant (industrial hard insulation calcium silicate board, hard calcium silicate stone type)" and "fire insulation of the building enclosure of the steam turbine room (calcium silicate board for buildings)". The application parts are different, and the temperature resistance and density requirements of the calcium silicate board are also different, so the calcium silicate material used is also different. Below, the editor of
Rosewool Insulation Refractory Co.,Ltd. will provide you with a detailed explanation and introduction;
The insulation application of calcium silicate board in the steam turbine plant mainly focuses on the equipment foundation, walls, pipeline supports, and the protective coating of the turbine casing inside the plant. Unlike the insulation of the steam turbine body (which requires the use of specialized materials and adherence to specific design specifications), the insulation of the plant area focuses more on the comprehensive needs of moisture prevention, fire prevention, structural protection, and thermal insulation. The steam turbine room belongs to a high-temperature plant, and the building walls, partitions, and ceilings are made of building calcium silicate boards, focusing on "fire prevention, heat insulation, and sound insulation", rather than being in contact with high-temperature steam equipment.
Functional Effect of Calcium Silicate Board in Turbine Building
- "Steam turbine room firewall and fireproof partition wall": Divide the fire compartments of the steam turbine room, distribution room, and control room to block the spread of flames and high-temperature radiation.
- "Ceiling and cable trench/cable tray wrapping in the steam turbine room": fireproof sealing to block the spread of high-temperature smoke.
- "Factory enclosure lining and equipment partition": isolate the high-temperature area of the steam turbine from the control room and duty room, reduce the ambient temperature of the duty room, and reduce noise.
- "Steel Structure Fire Protection Lining Plate": Covering the steel columns and beams of the steam turbine room to provide fire and thermal insulation protection for the steel structure.
Core Advantage of Using Calcium Silicate Board in Steam Turbine Plant
- A1 level non combustible, power plant fire safety compliance;
- Hard molding, high compressive strength, resistance to long-term vibration of steam turbines, and not easy to settle or collapse;
- Low thermal conductivity, stable insulation, significantly reducing the ambient temperature of the factory and improving the working environment for operation and maintenance personnel;
- Stable size, small shrinkage rate at high temperatures, and the board can be cut and processed on site;
- Resistant to aging, suitable for high temperature, high water vapor, and high dust conditions in steam turbine rooms.
Precautions for Selecting Calcium Silicate Board in Steam Turbine Plant
Choose Hydrophobic Calcium Silicate Board
The high humidity, high temperature, and dense steam in the turbine building make ordinary boards susceptible to moisture infiltration due to condensed water, resulting in insulation failure and structural deformation. Therefore, hydrophobic calcium silicate board should be given priority in the factory area, with an exclusive hydrophobic formula added. Its water absorption rate is much lower than industry standards, and it can maintain structural integrity, without powdering or deformation even in high humidity environments.
Strict Composite Temperature Resistance Standards Required
The performance requirements, especially the operating temperature, thermal conductivity system, compressive strength, and asbestos content, must strictly follow the application indicators of different parts;
