Increasing lifetime of metallic recirculating radiant tubes
Radiant tubes operate at a high thermal and mechanical load. A failure of the radiant tubes reduces the heat input to the furnace and therefore the productivity. In the worst case, furnace downtime is necessary. Besides choosing the appropriate material and a good dimensioning of the burner-radiant tube-system, different influences lower the lifetime of radiant tubes. This article gives an overview of the state of the art and experimental and numerical investigations concerning the influences on radiant tube lifetime.
