Kromschroder ceramic tube set TSC100B065-300/35-Si-1500 74918152

The Kromschroder Blast tube TSC100B065-300/35-Si-1500 (SKU 74918152) is a conical, tapered ceramic tube made of silicon-infiltrated silicon carbide (SiSiC). It is intended for Kromschroder BIC and BICA burners of size 100. The tube is 300 mm long, has an outlet diameter of 65 mm, and a distance from flange to front edge of 35 mm. It is rated for temperatures up to 1500 °C and withstands thermal shocks. The set includes seals and requires no additional burner quarl. It provides electrical insulation for electrodes and thermal insulation for seals.

Ceramic blast tubes are selected by matching the burner size, tube length, outlet diameter, and flange-to-front-edge distance to the existing part. The geometry is fixed by the burner model, so a replacement must match the old tube in every physical detail. Before ordering, measure the old tube, note the mounting orientation, and verify the part number against the burner documentation. During installation, confirm that all pieces are present and assemble them in the correct order. The ceramic is brittle, so handle it carefully to avoid chips.

Ceramic tubes of this type typically fail by developing cracks, spalling, or chips from thermal shock or mechanical impact. Damaged tubes no longer fully protect metal parts from heat or insulate electrodes and seals, which can lead to unstable flame, uneven heat distribution, and overheating of burner components. Inspect the old tubes for cracks and spalling when servicing the burner.
