Steam Turbine Design Marine Steam Turbines The Steam Turbine

Abstract

THE literature of steam turbines grows apace. This growth is seen to be natural enough when one considers the immense developments which have taken place in prime movers of the type during recent years, as well as their varied applications for land and marine purposes. On land, steam turbines are now almost universally preferred to reciprocating engines for electric generating stations; while low-pressure turbines are largely utilised—as auxiliaries to reciprocating engines—in iron works, factories, and engineering establishments. One of the most notable developments in modern mechanical engineering consists in the adoption of methods for utilising heat which had previously been wasted in carrying on manufacturing processes. In this endeavour to secure increased economy the steam turbine has played a great part, although its successful applications have unquestionably been greatly assisted by the work of electrical engineers. The fundamental principle of this increased economy is found in the capability of steam turbines, especially those of the “reaction” type, to carry the expansion of steam much further than is practically possible with reciprocating engines. Superheating, higher vacuums and greatly improved arrangements for condensing steam have necessarily had to be devised in order that the full efficiency of turbines might be realised; and it is worth noting that these advances have not only produced beneficial results in association with the use of steam turbines. Their range of usefulness has been much wider, and has affected the economical use of earlier types of reciprocating engines, both afloat and ashore.
