Rauschert Ceramic infra-red plaque 26453-1G01-102

This ceramic infra-red plaque is a spare part from Rauschert. It measures 205 mm in length, 93 mm in width, and 13.5 mm in height. It forms the radiating surface in infra-red gas burners, where a premixed gas-air stream passes through the plaque and burns on its surface, heating the ceramic to incandescence and producing infra-red radiation.

Parts of this type are selected by matching external dimensions and the pattern of the gas-air passage holes to the original article. The mounting frame and seal must be compatible; if the burner uses multiple plaques, replace all at once to maintain uniform surface temperature. During installation, ensure the ceramic is not cracked or chipped and that the gasket between plaque and burner body is in good condition.

Cracks or chips in the ceramic can cause uneven flame or incomplete combustion. A deteriorated seal may produce a gas leak, leading to unstable flame or backfiring. Inspect the plaque surface and the sealing condition when the burner shows irregular operation.
