Abstract: An insulator for use with a steam discharge tube of the type having two parallel rows of oppositely facing steam discharge apertures is disclosed. Two elongate channel sections having elongate channel edges are positioned transversely between the two rows and extend longitudinally along the tube on opposite sides of the tube. Sealing and spacing means serves to seal in spaced apart relationship the channel sections from the tube on respective opposite sides of the tube and provision is also made for securing said sections to the tube when in their desired location. The resultant insulator in assembled form reduces unwanted condensation production from the steam discharge orifices and also due to no use or the reduced use of polymers, the generation of unwanted off-gases.
