During operation which device listed removes air and non-condensable gases from the unit shown in the illustration? Illustration MO-0111
AI Explanation
The correct answer is A) "21".
The device labeled "21" in the illustration MO-0111 is the air vent or air release valve. This component is responsible for removing air and non-condensable gases from the unit shown, which is typically a steam or hot water system. The air vent allows the system to operate more efficiently by preventing air pockets and ensuring proper circulation of the working fluid.
The other options are incorrect because they represent different components of the system, such as the pressure gauge (22), the steam trap (25), and the return line (27), which do not specifically remove air and non-condensable gases.
