Within the last twenty years, radical changes have taken place in the methods and appliances for the generation and distribution of power.
Learn MoreSuperheated steam can be considered as a dry gas and therefore carries no moisture. Consequently there is no chance of pipe erosion due to suspended water droplets, and steam velocities can be as high as 50 to 70 m/s if the pressure drop permits this. The nomograms in Figures 10.2.9 and 10.2.10 can also be used for superheated steam applications.
