For users who use industrial steam boilers, they must pay attention to the failure of the downcomer with steam. Once the boiler's downcomer contains steam, it will easily cause the boiler to malfunction, causing serious consequences, and endangering personal health and economic property.
For industrial steam boilers, what is the hazard of carrying steam in the downcomer? Let Song Gong, the boiler technical engineer of Zhengzhou Fangkuai Boiler Factory, tell everyone the answer.
When the water in the downcomer contains steam, the average density of the working fluid in the downcomer will decrease, and the cyclic motion head will decrease. At the same time, the average volume flow of the working fluid will increase, and the flow velocity will increase, resulting in an increase in flow resistance, resulting in overcoming the resistance of the rising pipe. The reduction of the capacity and the reduction of the circulating water speed increase the possibility of failures such as circulation stagnation and reverse flow.
However, Song Gong also reminded everyone here that industrial steam boilers also have measures to prevent steam in the downcomer.
For industrial steam boilers, some measures are mainly taken in the structural design for the reasons for the steam, such as: installing a cross baffle or grille at the entrance of the large-diameter downcomer; increasing the low enthalpy of the feed water and introducing the low enthalpy feed water to Inside (or near) the inlet of the downcomer. To prevent the downcomer from heating, specify the distance between the steam-water mixture and the inlet of the downcomer, and the downcomer is led out from the bottom of the steam drum. During operation, attention should be paid to maintaining the water level of the steam drum to prevent the downcomer from carrying steam when it is too low.
After all, industrial steam boilers are still pressure vessels. In the process of using the boilers, users must first put safety issues first, and guide the boiler workers to regularly inspect the operation of the boiler, and solve the problems in time to avoid major disasters.
