Question 96Steam Plants - Assistant Engineer
70% to passVent condensers are usually an integral part of deaerating feed heaters and serve to condense _______________.
Athe gases liberated by the deaeration process
Bonly steam vented from high-pressure steam traps
Csteam vented from high-pressure steam glands
Dthe steam vapor entrained with the non-condensable gases
AI Explanation
The correct answer is D) the steam vapor entrained with the non-condensable gases. Vent condensers are used in deaerating feed heaters to condense the steam vapor that is entrained with the non-condensable gases (such as oxygen and carbon dioxide) that are removed from the feedwater during the deaeration process. This helps to reduce the volume of the vented gases and improve the overall efficiency of the deaerating feed heater. The other answer choices are incorrect because they do not accurately describe the primary function of the vent condenser in a deaerating feed heater system.
