Principle of boiler

The boiler is a kind of energy conversion equipment, the energy input to the boiler has the form of chemical energy in the fuel, electric energy, heat energy of high temperature flue gas, etc., and after the boiler conversion, the output has a certain heat energy of steam, high temperature water or organic heat carrier. It is widely used in thermal power stations, ships, locomotives and industrial and mining enterprises.

The main working principle of the boiler is a thermal equipment that uses the heat energy released after the combustion of fuel or the waste heat in industrial production to transfer to the water in the container, so that the water reaches the required temperature or a certain pressure steam. Boiler in the "pot" and "furnace" two parts at the same time, after the water into the boiler, the boiler heating surface will be absorbed in the water supply system, so that the water heated into a certain temperature and pressure of hot water or steam, is drawn out of the application. In the combustion equipment part, the fuel combustion continues to release heat, the combustion of high temperature flue gas through the spread of heat, the heat transfer to the boiler heating surface, and its temperature gradually decreases, and finally discharged by the chimney.
