Rauschert Ceramic infra-red plaque 26358/7-8101-101

Rauschert Ceramic infra-red plaque 26358/7-8101-101 is a spare part made of ceramic, measuring 132 mm in length, 92 mm in width, and 12.5 mm in height, with tolerances of ±0.3 mm, ±0.3 mm, and ±0.4 mm respectively. It is designed to produce high-intensity radiant heat output and is made from natural materials, giving it a neutral shade. The plaque must withstand repeated thermal cycling and operates at very high surface temperatures.

When selecting a replacement plaque of this type, verify that the length, width, and thickness match the original part, including tolerances. The fit must be precise to prevent gas leakage or flame transfer around the edges. Inspect the sealing face before fitting and ensure the burner housing is clean and free of debris. Handle with care during installation to avoid chipping or cracking, as the ceramic is brittle.

Plaques of this kind can fail due to thermal cycling, leading to cracking or spalling. Blocked pores or damage to the surface can impair flame stability and radiation uniformity. Check for any visible damage or debris on the plaque surface and ensure it is seated properly in the burner head.
