Working Principle and Application Classification of

After water enters the boiler, the heat absorbed by the heating surface of the boiler in the steam-water system is transferred to the water, so that the water is heated to a certain temperature and pressure of hot water or steam, which is introduced for application. In the part of combustion equipment, fuel combustion continuously emits heat.


A solid (a block of metal, say) has one surface at a high temperature and one at a lower temperature. This type of heat conduction can occur, for example, through a turbine blade in a jet engine. The outside surface, which is exposed to gases from the combustor, is at a higher temperature than the inside surface, which has cooling air next to ...
