What are the reasons for high load in the settling tank?
Thread Content
The slag discharge pump at the bottom of the settling tank is not working properly, the agitator of the settling tank inside is not working properly, and the flocculant added is insufficient. Are there any other reasons?
Personally, I think the settling tank agitator is not working properly. First, check the coal quality and combustion conditions, how much or how much flocculant is added, and the pressure indication in winter is abnormal (probably due to weather). The slag discharge pump at the bottom of the settling tank is not working properly. First, check the pump itself, and then look at the operation of the filter press and the condition of the filter cake. If too little flocculant is added, the settling effect will be poor; if too much is added, the filter cake will be abnormal. This is for reference only!
What was said upstairs is basically what I want to say. I would like to add that it is a mechanical problem. It also depends on whether the design of the overflow pipe is reasonable.
Replenish: 1. Is the oxygen-to-coal ratio control appropriate? 2. There is too much fine ash in the black water. 3. The coal quality changes greatly. ；

I wonder if it has something to do with the previous flash evaporation system?
Sometimes it is caused by the filter press not working properly. In addition, the scale may fall off due to frequent stops and starts, which may affect the normal operation of the pump.
I don’t understand. What does high load in the settling tank mean? Is it high liquid level? Is the drain valve at the bottom blocked?
