Description

Technical Field

[0001] The utility model relates to the technical field of boiler water preheating and temperature raising device, and more specifically, it relates to a boiler water preheating and temperature raising device. Background Art

[0002] The main working principle of the boiler is a thermal device 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 of steam. The boiler is operated simultaneously in the "pot" and "furnace". After the water enters the boiler, the boiler heating surface in the steam-water system transfers the absorbed heat to the water, so that the water is heated into hot water of a certain temperature and pressure or generates steam, which is then drawn out for use. In the combustion equipment part, the fuel combustion continuously releases heat, and the high-temperature flue gas generated by the combustion transfers heat to the boiler heating surface through heat transfer, while its own temperature gradually decreases and is finally discharged from the chimney.
