What type of combustion engine would you classify steam turbines used in power plants?

Steam turbines are external combustion engines.


Comparison between internal combustion engines and external combustion engines?

Internal engine has its energy ignited in the cylinder. like 99.9% of engines today An external combustion example is a steam engine where the heating prosses is done in an boiler out side the engine.


What is external combution engine?

External Combustion engine is an engine in which combustion of fuel takes place outside the cylinder. e.g.Coal fired steam engines in trains


Difference between internal combustion engines and steam engines?

Internal combustion engine is where the fuel is ignited in the cylinder to make the piston move, petrol or diesel. A steam engine has an external pressure vessel to supply the steam to the cylinder to push the piston. the is no combustion in the engine as such.


Is steam power plant is internal combustion or external combustion engine?

A steam engine is an external combustion engine.


Difference between internal combustion engines and external combustion engines?

In an Internal Combustion Engine, the fuel is burned in the cylinder or vessel. Eg. Diesel or Petrol engine used in Cars.Internal engine has its energy ignited in the cylinder, like 99.9% of engines today.In an External Combustion Engine, the internal working fuel is not burned. Here the fluid is being heated from an external source. The fuel is heated and expanded through the internal mechanism of the engine resulting in work. Eg. Steam Turbine, Steam engine Trains. An external combustion example is a steam engine where the heating process is done in an boiler out side the engine.


What is an external combustion engine?

An external combustion engine is one in which the oxidation of the fuel occurs outside the engine, which provides heat to the motive portion of the engine. External combustion is characterized by burning the fuel outside of the moving parts, as opposed to burning fuel inside the cylinders of an internal combustion engine. The Steam engine, using steam pressure, is an example of external combustion, as in the "Stanley Steamer," an early motorcar; and in steamships The combustion is in the boiler, not in the cylinders that convert steam pressure and volume to mechanical work. Internal combustion engines include diesel and gasoline vehicles (explosive fuel mixes), gas turbines, and most jet aircraft engines.


What is the difference between internal combustion engine and external combustion engine?

In an Internal Combustion Engine, the Fuel is burnt in the cylinder or vessel eg. Diesel or Petrol engine used in Cars.Gasoline engines, Wankel engines, diesels, gas turbines are all examples of internal combustion.In an External Combustion Engine, the internal working fuel is not burnt. Here the fluid is being heated from an external source. The fuel is heated and expanded through the internal mechanism of the engine resulting in work. eg. Steam Turbine, Steam engine Trains.


Heat engines use heat to do work?

Yes. Heat engines come in various forms. For example, internal combustion using gasoline or diesel, external combustion (not much used), steam engines reciprocating or turbine, gas turbines, rocket engines.


What kinds of engines powered automobiles in the early 1900s?

There were gasoline and diesel engines, as today, but also some early steam engines (external combustion), notably the Stanley Steamer (1902-1924).


What type of combustion engine is the steam engine?

It is External-combustion engine.


What is a steam engine an example of?

A train DUHHH! An external combustion engine.
