Richard Trevithick, British mechanical engineer and inventor who successfully harnessed high-pressure steam and constructed the world's first steam railway locomotive (1803). In 1805 he adapted his high-pressure engine to driving an iron-rolling mill and to propelling a barge with the aid of paddle
The 'pressure loss bar/100 m' scale reads about 0.9 bar/100 m. The pipe length in the example is 200 m, so the pressure drop is: This pressure drop must be acceptable at the process plant. Using formulae to establish steam flowrate on pressure drop. Empirical formulae exist for those who prefer to use them.
Pipe must be sized for the minimum pressure that is to be used without any insulation. To get a good conditioning of the meal and achieve good pellet quality from any feed mill, steam quality has to be corrected to the right quality reducing any chance of superheated steam .
