How Does the Steam Engine Work?
Are you interested in knowing the scientific reason of how does the steam engine works? So this blog will be really helpful to know how does the steam engine works.
Earlier, In 1804 the first steam-powered engine ran, containing some iron in Wales, in Britain. But it was around 20 years later, in 1829, that George Stephenson, a British engineer, structured the “rocket” that made the way for railways all over Europe, Asia, and America.
The steam engine is an example of a heat engine. Heat motors are those that convert heat energy into mechanical work.
Do you know there is various type of heat engines?
Type of heat engines
Heat engines are of two different types:
- External combustion engines
- Internal combustion engines.
In an external combustion engine, The fuel is burned outside the chamber(cylinder) that produces power. In an internal combustion engine
The steam engine is a case of an external combustion engine while a vehicle has an inside combustion engine. As a result, the steam motor comprises:
- a boiler
- safety valve
- steam reservoir
- piston and
- a drive wheel.
What is required to make the steam engine work
Firstly, A steam engine needs steam to make it go. Coal from a coal delicate is fed into the firebox where it is burnt at a temperature of 1400 degree C. This heat is utilized to turn water, also stored in the tender, into high weight steam.
This high-weight steam energy is made to go from the boiler to the steam supply through steam funnels. A slide valve in the piston opens and closes two steam ports, on the other hand. This guarantees the steam goes through alternate ports.
The piston is associated with a drive wheel. At the point when the steam goes into the slide valve, it pushes the piston to the right side and turns the wheel. The left valve closes and the right valve is opened letting in steam on the opposite side of the piston.
Right now, steam entering this valve pushes the piston to one side and drives the wheel to a complete circle. This procedure continues rehashing and drives the train forward.
The heavy drive wheel is fixed to the crankshaft of the motor. Also, a speed governor controls the speed of the motor. In specific motors, a portion of the steam that has gone through the piston is still hot to re-heat a portion of the cold water before it enters the boiler. The rest of the spent steam billows out of the chimney.
Therefore today, most of the functions of steam engines have been taken over by internal combustion engines fueled by diesel which are being replaced by the more environmentally sound electric motors.
