當加熱溫度至所需溫度前5~10℃時，即需將關閉蒸氣至溫度到達時，間段開啟排水開關以排去夾套內殘餘之蒸氣，以防槽內溫度過高。

結果 (英文) 1:

When heated to the desired temperature before the temperature 5 ~ 10 ℃, i.e. need to be close to the vapor temperature reached, opening the drain inter-segment switches to discharge the residual steam in the jacket to prevent the temperature in the tank is too high.

結果 (英文) 2:

When the heating temperature to the desired temperature before 5 to 10 degrees C, that is, the switch off steam to the temperature to reach, the middle section opens the drainage switch to remove the residual vapor in the jacket, in order to prevent the temperature in the groove is too high.

結果 (英文) 3:

When the heating temperature reaches 5-10 ℃ before the required temperature, it is necessary to turn off the steam until the temperature reaches, open the drain switch in the interstage to drain the residual steam in the jacket, so as to prevent the temperature in the tank from being too high.
