It is said that " Neptune " and sister ship were the last ships in the Navy to operate using reciprocating steam engines.
22.
This direct drive arrangement is mechanically most efficient, and reciprocating steam engines are well suited to the rotational speed most efficient for screw propellers.
23.
This new technology ultimately replaced the old reciprocating steam engine and was the predecessor of all steam-station turbine electric generators in America today.
24.
All the ships to be built were collectively called the triple-expansion reciprocating steam engine and coal-fired Scotch-type fire tube boilers.
25.
Her triple-expansion reciprocating steam engine was built by the Greenock Foundry, and developed, sufficient to propel her at through her single screw.
26.
"Kurama " used the traditional pair of four-cylinder reciprocating steam engines with a power rating of, more than the older ships.
27.
She was powered by 14 Babcock & Wilcox boilers driving two dual-acting vertical triple expansion reciprocating steam engines, with, with a maximum speed of.
28.
Originally equipped with reciprocating steam engines, during its long life a total of eighteen generating sets were installed and in turn replaced with larger units or scrapped.
29.
The cycle of a reciprocating steam engine differs from that of turbines because of condensation and re-evaporation occurring in the cylinder or in the steam inlet passages.
30.
Westinghouse felt that reciprocating steam engines were clumsy and inefficient, and wanted to develop some class of " rotating " engine that would be more elegant and efficient.
