It is an engine.
A steam turbine is a heat engine that uses the expansion of steam passing through stationary nozzles and blades on a shaft to turn the shaft. The steam can move through the turbine axially (one end of shaft to the other end), radially (shaft to outer casing), or tangentially (around the outer edges of the turbine wheel). In an impulse turbine, the steam is expanded in nozzles and pushes the blades. In a reaction turbine the steam is expanded in the nozzles AND in the blades, the reaction of the expansion of the steam pushes away from the blades spinning the wheel in the process. The expansion of the steam is necessary to increase its velocity through the turbine.

They would think it's good because people who drive airplanes use it to generate the plane.

Allegedly, 6 people found that rhubarb "useful"..... I hope they were not plagiarists!

I cannot imagine why a modern aircraft designer would think of using a steam engine to power an aeroplane, because the power/weight ratio is far poorer than that of an equivalently-powerful internal-combustion (inc. gas-turbine) engine, and the overall system is more complicated.

Note that this stamp is not from 1866, it is the date the steam carriage was created.

Minimal value for this stamp indicates that the cost is in packaging and tracking and not the stamp itself. A dealer isn't going to be interested in purchasing a single copy. You would be better to use it for postage rather than trying to sell it. Or trade with another collector!

Actually feed pump in the boiler is used to send water inboiler that is converted into steam whose kinetic energyis used to produce electricity. This pump can be driven byelectricity or steam from Turbine. In steam driven pumps, steam from tubine is bledand used to drive the impeller of pumpand send water in boiler.

Steam engines were first used in the tin mines of Cornwall, England to pump water from the mines which often extended out under the Cornish coastline.

the work of the condensor is to condense the hot steam and change its state so that it can be used again in boiler

James Watt (1736-1819) is credited with the 1765 improvement of the steam engines of Thomas Newcomen (1664-1729), which dated from 1712. The efficiency of the Watt engine led to its wide industrial use after Watt partnered with Matthew Boulton in 1775.

The application of steam power to manufacturing allowed industry to speed up and scale up their production processes.

The procedure for starting draft plant (fans) in a boiler is to start the ID Fan first.

Remember that the purpose of the ID Fan is so that the Furnace operates at a slight vacuum. (See Related Link: FD Fan vs ID Fan.)

Any casing or furnace leaks then allow air to leak in, rather than allowing air with pulverised fuel and fly ask to leak out.
