Investigation on the renovation effects of circulating water turbines

There is definitely an energy-saving effect, but it is necessary to take into account the specific circumstances of one’s own company as well.
Previously, someone came to pitch it, but the factory refused.
I was initially opposed to it as well, but after carefully studying the water pumps and piping systems, I realized that optimization of the system is possible; therefore, I want to find more examples to study
The return water pressure can be used to drive the turbine, which in turn powers the cooling fan; this allows that pressure energy to be recovered – thereby enabling cooling of the cooling tower without the need for electricity. Last year, someone came by to pitch this idea, but the owner didn’t go for it~~ Hehe~~
The main issue might be that increasing the pump’s head results in higher power consumption, and there isn’t much room for energy savings regarding the power used by the cooling fans
On the surface, that’s the case; it depends on how much potential for optimization exists in the pump and piping system
The main purpose of a turbine is to recover the energy from the residual pressure of the returning water; if there is no high point for the water, it is not necessary to make technical modifications, and optimization should be carried out on the pump side instead. After all, the energy of the turbine comes from the water pump; if it can be optimized earlier, there’s no need to optimize it later, as it’s not cost-effective. If there are high points where water is needed, a system pressure is required, and using a turbine is a suitable approach.
Different analyses should be conducted for different systems; it’s not possible to generalize.
Not all circulating water systems can be connected to turbines; it depends on the volume of water in circulation and the pressure required to pump water to the cooling tower. In simple terms, this takes advantage of the fact that most factories choose water pumps with a pressure level that exceeds the actual requirements. It is recommended to develop a plan for energy savings in conjunction with the circulation pump and the pipeline network, in order to compare which approach is more cost-effective.
It’s consistent with my earlier views, but I now have new understandings.
