Steam locomotive


Steam locomotive is moved by using the power of steam which is generated in its own boiler by the combustion of fuels such as coal, oil or petroleum. Steam locomotives are also used to move trains along railway tracks for railway transport.

Steam engine


Steam engine is a heat engine in which a hot steam is used that converts the heat energy into mechanical energy. Sliding piston is present in the cylinder which moves by the expansion action of the steam which is generated in a boiler. Coal, wood or other combustible material are used as a source to produce steam in a boiler.

Global warming


Global warming can be defined as an increase in the average temperature of the earth's atmosphere that causes changes in the climate which may result from the greenhouse effect. Burning of coal is one fo the cause that generates carbon dioxide and other gases which may  increase temperature. Several other factors are also responsible for global warming.



Boiler is a closed vessel in which water or other types of fluids is heated as a result vapour or steam is generated which helps to run turbines or engines and also heat produced is used for various other purposes. The sources of heat for the boiles is combustion of different fuels such as coal, natural gas, wood or other types of fuels.
