The relationship between turbine back pressure, air intake volume, and the cooling efficiency of the air cooler!

There is a problem with your analysis. Turbines equipped with air coolers: The heat exchange efficiency of the air coolers decreases in summer when the ambient temperature is high ； ---》The ambient temperature is high, so the exhaust temperature is high. A decrease in the heat exchange efficiency of the air cooler leads to an increase in the back pressure of the turbine ； ---》As the ambient temperature rises, condensation cannot occur in a timely manner, resulting in increased pressure. The higher backpressure on the turbine leads to a decrease in the thermal efficiency of the steam ； ----》This sentence is appropriate. To ensure that the turbine can do work, it is necessary to increase the amount of air supplied to the turbine ； ----》 Increased steam volume leads to higher energy consumption. The air intake volume of the turbine increases, but the heat exchange efficiency of the air cooler declines; as a result, an increasing amount of steam cannot be cooled ； ----》This statement is incorrect. When the air intake to the turbine increases, as long as it remains within the design limits, the waste steam measured in the exhaust gas can still be condensed; only the condensation temperature rises. Understood? ? ? In other words, the exhaust steam can be condensed, as the air cooler is very effective; however, the temperature of the air used for heat exchange rises, and as a result the temperature on the steam side also increases. But this does not mean that condensation cannot occur – it just means that the temperature rises, yet condensation is still possible. Is this a vicious cycle?

Thank you, I truly appreciate your clarification! It’s the answer to the last sentence. I’ll reply first, then I’ll think it over~

This approach will only work in the short term and cannot solve the underlying problem. The focus should mainly be on the design and selection of the air cooler; of course, there’s a bit of ** here. The poster can try some technical improvements to see if increasing humidity during the summer can enhance the cooling effect of air cooling~~

I am currently looking for information on measures to increase internal humidity; if there are any relevant construction methods, please share them. It involves spraying the cooled condensate in a mist form into the exhaust pipes, thereby reducing the exhaust temperature and decreasing the load on the air cooler. This approach is not widely used in China

Making the air cooler too large increases the initial investment, and the design temperature of the air cooler cannot be set at the highest possible value; when the ambient temperature exceeds this design temperature, external measures are necessary to ensure the safe operation of the unit!

Is there any good way? ? ? For air coolers, especially in summer

The internal humidification effect is good, but work on it can only be carried out during a major maintenance session. Additionally, nozzles can be installed under the fan to create mist, though this wastes desalinated water... Each method has its advantages and disadvantages; does anyone have an system for internal humidification, and what are the results?

How exactly is it done, and will it have no impact on the fan motor? Are there any specific photos or construction drawings?

Our facility uses external mist nozzles to spray desalinated water onto the tube bundle

It is essential to avoid getting the motor wet~~
