Steaming Machine Advantage Aug 25, 2017

A steam engine is a reciprocating power machine that converts the energy of steam into mechanical work. The emergence of the steam engine has caused the 18th century industrial revolution. Until the beginning of the twentieth century, it was still the most important motive in the world, and later gradually gave way to internal combustion engines and turbines.

The steam engine needs a boiler that boils water to produce high-pressure steam, which can use wood, coal, oil or natural gas and even combustible waste as a heat source. Steam expansion drives the piston to work.

Steam engine mainly by the cylinder, base, piston, crank connecting rod mechanism, slide valve with steam institutions, speed control agencies and flywheels and other components. The cylinder and the base are stationary.

In a steam boiler, the water is boiled into steam by burning. Through the pipeline steam was sent to the cylinder. The valve controls the time the steam reaches the cylinder and enters the slide valve chamber through the main steam valve and the throttle valve, which is controlled by the spool valve alternately into the left or right side of the cylinder to push the piston movement. Steam in the cylinder to push the piston work, cooling the steam through the pipeline was introduced into the condenser to re-condense into water. This process is repeated during the steam engine movement.

The general steam engine has three cylinders to form a group. The steam engine directly converts the up and down movement of the piston into the rotary motion of the axle. The new steam engine also contains a small turbine, steam from the cylinder can also use its waste heat in the promotion of the turbine to improve the efficiency of the entire drive device. The turbine is also connected to the propeller shaft of the ship.

Advantages: The biggest advantage of modern steam engines is that it can use almost all of the fuel to convert thermal energy into mechanical energy. Unlike the internal combustion engine, it is not critical of its fuel. In addition there is no steam engine, then atomic energy can not be used. Atomic reactors do not directly produce mechanical energy, and do not directly generate electricity, the atomic reactor is actually only heated water, the water is boiled after the steam through the steam engine to convert useful useful. Steam does not necessarily need to be produced by combustion, such as the use of solar heaters can also produce steam to promote the steam engine.

Another small-sized external combustion engine with similar advantages is the Stirling engine. The downside is that it is difficult to run in many cases.

Especially in the mountains on the advantages of steam locomotives significant, because they can also run at relatively low pressure. This will be found when South America will replace its steam locomotives with diesel-electric locomotives. In the mountains they had to give up the use of relatively high power diesel locomotives, replaced by power, but not as diesel locomotives but not by sea limit steam locomotive.

The use of modern steam engines in Swiss and Austrian new railroad cars requires only one person to run, saving 60% more fuel than the past, and 50% lighter than the electric and diesel engines, The wear is much smaller. There is also a new steam engine ship on Lake Geneva, the world's first remote control steam engine.
