Power plant steam turbine plant is the steam energy into an important part of the power is one of the core power plant, the indoor temperature perennial at 28-40 ℃. The steam turbine cylinder, high pressure main steam valve and air pipe, medium pressure reheat valve and steam pipe and other equipment, insulation surface temperature for a long time at 80 ℃ above. The working environment is very bad. In order to reduce the appearance of equipment cooling, the thickness of the traditional insulation materials generally need 280-330mm, in fact, the traditional materials in the design of the national standard parameters at the same time, the design thickness is also increased by 1.3 coefficients, and then such over-design of the insulation surface The temperature should be about 57 ℃, but the actual situation is above 80 ℃. This situation is ubiquitous in the power industry. It can be seen from this point, the traditional insulation materials in the actual use of high temperature conditions, the material defects revealed. Thick insulation layer not only failed to meet the design requirements, but also sacrificed a large amount of equipment maintenance space, making maintenance difficult maintenance.

Traditional insulation defects Summary:

The thermal conductivity of traditional insulation materials in the high temperature rise, thermal insulation properties decreased.
Traditional thermal insulation materials less contact layer thermal resistance is small, the gap between the material easy to form a thermal bridge, thermal insulation effect dropped significantly.
Traditional insulation materials, insulation thickness, low bulk density, easy deformation, high pressure cylinder wrapped 330mm aluminum silicate, the material is self-weight compression, substantially reduce the insulation performance.

Tradematt Aerogel Insulation Materials Solution:

Steam turbine cylinder insulation

Technical Parameters: Surface temperature 566 ℃;
Features High surface temperature, shaped, requiring regular maintenance.
Ordinary insulation method:

The inner layer of aluminum silicate cotton, outer barbed wire fixed, wiping the surface layer.

After using aluminum silicate will gradually sedimentation, thermal insulation effect decreased.

Two years replacement

Issues that need resolving

1, the thermal insulation effect is gradually decreased by the heat loss

2, the outer surface of the heat, the workshop temperature is high

3, insulation thickness, small space for maintenance

4, tedious maintenance, thermal insulation repeat investment.
