The automatic recirculating valve in the main condensate recirculating line is controlled by a temperature sensor which is located at the _______________.

Aair ejector condensate discharge
Bmain condensate pump suction
Cmain condensate pump discharge
Dcondensate inlet to the main air ejectors
AI Explanation

The correct answer is A) air ejector condensate discharge. The automatic recirculating valve in the main condensate recirculating line is controlled by a temperature sensor located at the air ejector condensate discharge. This is to maintain a specific temperature at the air ejector condensate discharge, which is important for the proper operation and efficiency of the main condenser system. The other options are incorrect because the temperature sensor would not be located at the main condensate pump suction (B), main condensate pump discharge (C), or condensate inlet to the main air ejectors (D), as these are not the critical points for controlling the recirculating valve.
