What is the wholesale price of ceramic fiber blanket insulation material for power plant pipelines? In power plants, pipeline insulation requires high material requirements – it must withstand high temperatures, have good insulation efficiency, and be able to adapt to temperature changes caused by frequent unit starts and stops. The application of ceramic fiber blanket in high-temperature pipelines of power plants has become very mature, especially suitable for working conditions such as main steam pipelines and reheated steam pipelines with temperatures exceeding 350 ℃.
How to choose the temperature resistance level of ceramic fiber blanket?
The two commonly used types of pipelines in power plants are 1050 ℃ and 1260 ℃, with long-term operating temperatures corresponding to around 900 ℃ and 1100 ℃, respectively. If higher temperature resistance is required, there are also options for 1400 ℃ grade (high aluminum type) and 1430 ℃ grade (zirconium containing type). The zirconia content of zirconium containing type is between 15-17%, which has stronger resistance to high temperature shrinkage. The thermal conductivity of different grades also varies, for example, at an average temperature of 400 ℃, the thermal conductivity of 1260 ℃ is about 0.085-0.110 W/(m · K), and at 600 ℃ it is about 0.152-0.20 W/(m · K).
Actual usage effect of ceramic fiber blanket in power plants:
1. Energy conservation and consumption reduction
The temperature of the outer wall of the bare steam pipeline can reach over 200 ℃. After being wrapped with multi-layer ceramic fiber blankets, the heat dissipation loss is reduced by more than 70%, and the coal consumption of the boiler is significantly reduced, improving the power generation efficiency of the unit.
2. Protecting pipeline equipment
Isolate high temperatures and slow down the oxidation and aging of steel pipes; To avoid the formation of acid water corrosion on the pipe wall due to the cooling and condensation of flue gas, extend the service life of pipelines and valves, and reduce the frequency of shutdown maintenance.
3. Factory safety protection
Low temperature on the outer layer of the pipeline to prevent scalding by inspection personnel; No high-temperature hot gas leakage, reducing the risk of high-temperature pipeline fire.
4. Stable operation of the unit
The temperature of steam and flue gas transportation is stable, avoiding temperature fluctuations that affect the operation of the steam turbine and denitrification system, and ensuring stable load of the unit.
