Destination of condensate water from steam boilers
Thread Content
A 20-ton steam boiler has been installed in the facility, along with a water softener and a deaerator. The condensate water returns from the process and is unpolluted; should it go into the soft water tank first or the deaerator? Additionally: Currently, the clean water pump that transports water from the soft water tank to the deaerator is controlled by the level of water in the deaerator. But how should it be controlled if condensate water enters the deaerator directly?
Go directly into the soft water tank for buffering.
Thank you, looking forward to the insights from all the bosses
I’ll change it to go straight back to the deaerator now, but you still need a soft water tank and a deaeration pump; if there isn’t enough water returning, additional water needs to be added
It’s a good idea, provided that the amount of water returning is small and it doesn’t affect the overall liquid level. Here, the deaeration pump draws water from the soft water tank into the deaerator; the liquid level in the deaerator is continuously controlled, and the deaeration pump is operated via frequency conversion control. So, if less condensate returns, the liquid level is easy to control; but if more returns and exceeds the level, it becomes problematic. In short: the water level control in the deaerator does not allow for control over the amount of condensate water returning. I wonder if you understand what this means? How should it be dealt with? ?
Thank you for your participation. Which is better, the deaerator or the other one?
In my opinion, when going directly to the deaerator, it is also necessary to consider the issue of poor quality of the condensate water, as this makes control difficult. In our plant, the condensate water returns to the water tank first and then is pumped to the deaerator; however, there are occasional instances where the returned water does not meet the required standards. According to the design and common sense, the quality of the condensate water should be sufficient for reuse, but in practice, unexpected situations can occur
That makes sense! Is the water tank insulated?
What is the temperature of the condensate return water? What is the operating temperature range of a water softener? If an advanced deaerator is used, the outlet water temperature will be 104 degrees. Will this exceed the operating temperature of the water softener? It is recommended to use an advanced water softener first, followed by a deaerator.
Thank you for participating! Are you referring to an advanced water softening tank or a deaerator? It has nothing to do with the water softener.
