Steam is an invisible gas generated by adding heat energy to water in a boiler. Steam is a very efficient and easily controlled heat transfer medium. It is most often used for transporting energy from the boiler to any number of locations in the plant where it is used to heat air, water or process applications.
The heat required to change boiling water into steam is called the heat of vaporization or latent heat.
1 ton steam heat is between 2.7-3.0 GJ, and accurate calculations need to know the steam parameters. The value of the large card is about 600,000 kcal. The heat of one ton of steam in a steam boiler is said to be standard; 1 ton steam = 0.7 MW = 250,000 kJ= 600,000 kcal. Based on this, we can estimate that the boiler with a capacity of 2 tons will generate about 1.2 million calories heat.
Starting in the combustion chamber of the boiler, heat flows through the boiler tubes to the water. It also forms in heating and process equipment as a result of desirable heat transfer from the steam to the substance heated. Once the steam has condensed and given up its valuable latent heat, the hot condensate must be removed immediately.
