Problems with the plant’s condensate water network
Thread Content
In your company, does the condensate water network send the water from all points together to the treatment station, or are there separate routes that lead to the treatment station? In our company, the water from all points is combined and sent to the treatment station, but in some areas we experience severe water hammer effects. I’m curious to know how other companies handle the flow of condensate water
Ours went to the boiler; the water hammer was caused by steam entering the condensate
After the merger, water was added to the recirculation tank; water hammer occurred, but since our steam pressure is low, the water hammer wasn’t severe
It is collected and sent to the supervisor for unified treatment in the condensate purification unit. Due to the large volume, no water hammer phenomenon has been observed.
After the mixing at various points, it goes to the treatment station; under normal production conditions, water hammer phenomena are not noticeable. Water hammer occurs after the shutdown or partial shutdown of certain sections. Low steam pressure; unable to push upward
Water hammer occurs because the condensate supplied by some units is cold and contains little steam, while in other workshops the temperature is high resulting in more steam. How can this problem be avoided?
Each workshop is equipped with a condensate tank; the flashed gas can be sent to the low-pressure header or introduced into the deaerator, etc
Each of our workshops is equipped with condensate tanks, and as required, coolers are also available to cool the water temperature before sending it to the coking reaction process for conversion into steam or to the boilers.
The coolant you have delivers water at a low temperature; without steam, there is no water hammer
Water hammer is caused by the different flow velocities of the vapor and liquid phases; therefore, avoiding this velocity difference will prevent water hammer!
