Answer: ① The feed water must be heated to the saturation temperature corresponding to the deaerator pressure. ② The gases that separate and escape from the water must be removed promptly. In 2017, in the field of coal chemical industry: “My Technical Upgrades” http://bbs.hcbbs.com/thread-1786290-1-1.html. In the petrochemical sector: The “Creative Ideas for Energy Savings” campaign (the second phase is currently in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html
1. The feed water must be heated to the saturation temperature corresponding to the pressure in the deaerator. 2. The gases that separate and escape from the water must be removed promptly
The two necessary conditions are: (1) The feed water must be heated to the saturation temperature corresponding to the deaerator pressure. (2) The gases that separate and escape from the water must be removed promptly
⑴ The feed water must be heated to the saturation temperature corresponding to the deaerator pressure. ⑵ The gases that separate and escape from the water must be removed promptly. Without this primary condition, the gas cannot be completely separated from the water ； When the second condition is not met, even if the quality of the dust collector deoxygenator is good, the gas that has been separated will return back into the water. It should also be noted that the process of separating gas from water, as well as the operation of dust collectors and deoxidizers, cannot be completed in an instant; it requires a certain amount of time for the gas to be separated.
The feed water must be heated to the saturation temperature corresponding to the pressure in the deaerator, and the gases that separate and escape from the water must be removed promptly
1. Heat the feed water to the critical saturation temperature corresponding to the current pressure in the deaerator. 2. Remove promptly the gases that escape from the water
① The feed water must be heated to the saturation temperature corresponding to the deaerator pressure. ② The gases that separate and escape from the water must be removed promptly.
