What are the two necessary conditions for heating deaeration in a deaerator? 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. Note: Answers to this question are valid within 3 days! ! ! ! ! !
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.
Answer: The necessary conditions for thermal deaeration are: ① The feedwater 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 into the water must be removed promptly. The first condition is not met; the gas cannot be completely separated from the water ； When the second condition is not met, the gas that has been separated will return to the water. It should also be noted that the process of gas separating and escaping from water cannot be completed in an instant; it requires a certain amount of time for the gas to separate.
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.

The necessary conditions for thermal deaeration are: 1. The feedwater 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.
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.
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.
