Overflow of the boiler water tank and understanding of its rated output capacity
The boiler water tank overflows. What are the specific reasons for this? Also, what is the rated output capacity of the boiler? These two questions above are both about boilers and are also very important and crucial. Therefore, below, they will be addressed through detailed answers to enable everyone to have a thorough understanding and profound recognition.
1.Analysis of the reasons for the overflow of the boiler water tank
If in the boiler, the water tank overflows, then it depends on which type of water tank it is. Because if the types of water tanks are different, then the reasons are also different. So below, an analysis and explanation of the specific situation will be carried out.
The overflow of the make-up water tank in the boiler, in terms of the main reason, is that the single-flow valve at the outlet has malfunctioned, such as the valve tongue not closing or the valve being damaged, causing the make-up water pump to stop operating. Furthermore, it causes the return water to flow back into the make-up water tank.
The overflow of the expansion tank in the boiler has several reasons. First, the initial water injection volume of the system is too much, causing the water to expand and overflow. Second, there is a problem with the on-off valve on the return water pipeline, causing the return water to flow back. In addition, the float valve in the tank being out of control can also cause the above problem.
2.What is the rated output capacity of the boiler?
The rated output capacity of the boiler, specifically speaking, refers to the evaporation capacity that the boiler can achieve under rated steam parameters, rated feed water temperature, and the correct selection of fuel, and it is under the premise of ensuring the design efficiency of the boiler.
For steam boilers, it refers to the rated evaporation capacity, and the unit is tons/hour; for hot water boilers, it is the rated heat output, and the unit is MW.
Regarding these two basic and important aspects of boilers, as long as we take them seriously and carry them out, we can have good learning results, and we can also have the effect of achieving twice the result with half the effort. In addition, on the learning path of boilers, we can advance well and, at the same time, increase our knowledge in this area and benefit greatly from it.
