Principle of large boiler

Principle of large boiler:

Boiler is a kind of energy conversion equipment, the energy into the boiler has the form of chemical energy in the fuel, electrical energy, the heat energy of high-temperature flue gas, etc., and through the boiler conversion, the output of steam, high-temperature water or organic heat carrier with a certain amount of heat energy.It is widely used in thermal power stations, ships, locomotives and industrial and mining enterprises.

The main working principle of the boiler is a kind of thermal equipment which makes use of the heat energy released after the fuel combustion or the waste heat in the industrial production to transfer to the water in the container and make the water reach the required temperature or a certain pressure steam.Boiler in the "pot" and "furnace" two parts at the same time, water into the boiler, in the steam system, the boiler heating surface will absorb the heat to feed water, so that the water is heated into a certain temperature and pressure of hot water or steam generation, is out of the application.In the part of the combustion equipment, the fuel combustion continuously gives off heat, and the high-temperature flue gas generated by the combustion transmits heat to the heating surface of the boiler through the heat transmission, while the temperature itself gradually decreases and is finally discharged by the chimney.
