Energy saving and consumption reduction through cooling tower renovation
Thread Content
A cooling tower was recently upgraded, with the drive system changing from motor-driven to turbine-driven. It is now in the debugging phase. I wonder which companies have used this type of setup before, what considerations are important during debugging, and what aspects need to be monitored during normal operation?
What a large cooling tower that must be, driven by a water turbine. What is the purpose of technological upgrades, and what are their benefits? The original poster might as well explain in more detail. I’m ignorant and unlearned; this is the first time I’ve heard of it. The cooling towers I’ve worked with in factories generally use belt drive or direct connection via reducers.
There are both belt transmission and direct connection options. The use of water turbines in cooling towers began to develop after 2008. The purpose is to save on electricity costs.
It’s very simple – just control the water supply valve and the return valve. The manufacturer will do the adjustments, and then hand it over to you.
Even small cooling towers can be used; a water wheel can replace the original motor to drive the blades for cooling, thereby saving some electricity. We modified two units, and the results were decent.
Can a closed-type cooling tower be modified for use with a turbine? ? ? ? ? ? ?
Yes, there are such things; some manufacturers have also recommended them to me. Could someone send over an energy-saving impact assessment to determine whether it’s cost-effective?
Before installing the upper turbine, the manufacturer conducts an assessment; generally, there are requirements regarding the return water pressure, with a value of over 0.12 MPa being sufficient. After the modification, electricity consumption by the drive motor can be reduced, provided that the current drawn by the water pump does not increase. It still offers good energy-saving effects; you might want to give it a try!

Many manufacturers have carried out energy-saving upgrades to water pumps; if such upgrades are done properly, then turbines are no longer necessary. The energy savings in this case fall under the category of pre-upgrade and post-upgrade energy savings. I think the pre-upgrade energy savings rate is higher, as after all, the efficiency of water pumps is already good, whereas turbines require a second stage of conversion, resulting in lower efficiency. You guys should take a look for yourselves.
Could you please introduce it, along with the daily precautions and maintenance tasks, so that I can learn from it? Thank you!
Contract energy management can be used: the manufacturer invests in the project, and you simply pay them back part of the money saved from reduced electricity costs – this way, everyone benefits. Our unit is currently in the preliminary assessment phase for renovation.
