The advent of large steam turbines made central-station electricity generation practical, since reciprocating steam engines of large rating became very bulky, and operated at slow speeds.
32.
Although the reciprocating steam engine is no longer in widespread commercial use, various companies are exploring or exploiting the potential of the engine as an alternative to internal combustion engines.
33.
She was powered by 12 oil-fired Babcock & Wilcox boilers driving two dual-acting, vertical triple-expansion reciprocating steam engines, with, with a maximum speed of.
34.
"KankM Maru " was a three-masted jackass-barque-rigged sailing vessel, with an auxiliary single-cylinder coal-fired reciprocating steam engine turning a side paddlewheel.
35.
After 1890 reciprocating steam engines rate as IHP ( indicated horsepower ) only, whereas steam turbines rate as SHP ( shaft horsepower ) and displayed as SHP or HP on Navy Lists after 1900.
36.
The'motor'in the formal designation, referring to the use of petrol engines, was to distinguish them from the majority of other naval craft that used steam turbines or reciprocating steam engines.
37.
Tesla developed many versions of the oscillator and looked on it as a possible replacement for inefficient reciprocating steam engines used to turn generators, but it was superseded by the development of highly efficient steam turbines.
38.
For example, Sebastian Ziani de Ferranti planned what would have been the largest reciprocating steam engine ever built for a proposed new central station, but scrapped the plans when turbines became available in the necessary size.
39.
The plant houses the last operable examples of early vertical steam generating turbines, as well as reciprocating steam engines, which are also operational, a collection of vintage machining tools, and several smaller steam engines.
40.
The Liberty ships were a throwback to late 19th century British designs with reciprocating steam engines, but were very cheap to build in large quantities; Victory ships evolved from the Liberty ships but used modern turbine engines.
