Does the pressure-bearing boiler belong to the category of special equipment? What are the types?

There are many types of boiler equipment on the market, and there are different types of boilers according to different standards. A pressure-bearing boiler is a kind of boiler equipment with internal pressure, corresponding to normal pressure and negative pressure boilers. Pressure-bearing boilers include steam boilers, heat-conducting oil boilers (also called organic heat carrier boilers) and pressure-bearing hot water boilers. Generally, pressure-bearing boilers refer to steam boilers and hot water boilers with a working pressure greater than 0.1MPa. Many industrial users have great demand for pressure-bearing boilers, but they don’t know much about the detailed information of the boilers. Let Zhengzhou Fangkuai Boiler Factory answer for you.

Pressure Boiler is the closed boiler that we usually see. The steam and water system in the boiler is composed of a closed container and pipeline, heated by a flame, and is subjected to fluid pressure during work. It is a special equipment. Therefore, whether it is an enterprise that manufactures a pressure-bearing boiler or an enterprise that uses a pressure-bearing boiler, it is necessary to carry out work related to safe operation and report to the relevant departments.

When there is a serious water shortage in a pressure-bearing boiler, the boiler must be stopped urgently, and water is not allowed to be added to the boiler.

The technical engineer of Zhengzhou Fangkuai Boiler Factory will answer for you: This is mainly because when the boiler suffers from a serious water shortage, it is unknown to what extent the water level of the steam drum will be. It may be that there is no water in the steam drum or the water wall is already Partially boiled and overheated. In this case, if water is forcibly added to the boiler, huge thermal stress will be generated due to the excessive temperature difference, which will damage the equipment. At the same time, when water encounters a hot metal surface, a large amount of steam will evaporate instantly, causing a sudden increase in vapor pressure, and even causing pipe bursts or more serious explosion accidents. Therefore, when severe water shortage occurs, it must be dealt with in strict accordance with the regulations, and it is never allowed to blindly fill the water.
