Steam turbines were fueled by coal or later, fuel oil, or nuclear power.
The marine steam turbine developed by Sir Charles Algernon Parsons, raised the power to weight ratio. He achieved publicity by demonstrating it unofficially in the 100-foot Turbinia at the Spithead naval review in 1897. This facilitated a generation of high-speed liners in the first half of the 20th century and rendered the reciprocating steam engine obsolete, first in warships, and later in merchant vessels.
In the early 20th century, heavy fuel oil came into more general use and began to replace coal as the fuel of choice in steamships. Its great advantages were convenience, reduced manning due to removing the need for trimmers and stokers, and reduced space needed for fuel bunkers.
In the second half of the 20th century, rising fuel costs almost led to the demise of the steam turbine. Most new ships since around 1960 have been built with diesel engines. The last major passenger ship built with steam turbines was the Fairsky, launched in 1984. Similarly, many steam ships were re-engined to improve fuel efficiency. One high profile example was the 1968 built Queen Elizabeth 2 which had her steam turbines replaced with a diesel-electric propulsion plant in 1986.
Most new-build ships with steam turbines are specialist vessels such as nuclear-powered vessels, and certain merchant vessels (notably Liquefied Natural Gas (LNG) and coal carriers) where the cargo can be used as bunker fuel.

I used to work on various merchant ships. The main fuels used were common diesel and what is called "Bunker C" which is a black heavy oil which need to be heated prior to use.
Both of these fuels were used in either boilers or diesel engines. In large slow speed diesel engines Bunker C maybe used. Merchant vessels may also use kerosene. I don't recall ever working on a ship which nurnt kerosene, not that it is not used some where but it may be an availability issue.
Boilers also may burn diesel or #3 (like heating oil) even though these are more expensive there are advantages as there is a little more heat value in the fuel and these burn much cleaner and do no require preheating like bunker C.
Having worked on a Military Sealift Command tanker for the US Navy, we carried and used just two fuel types(Not counting nuclear). These were JP4 for aircraft and diesel. In addition to the above advantages over Bunker C the two fuel system simplifies logistics.

The fuels are of three types :-
H1 [protium (used in the cars, buses, trucks etc.)], H2 [duetrium (used in ships)], H3 [tritium (used in rockets)]
