Question 167Steam Plants - QMED70% to pass
Cooling water to the vent condenser in a DC heater is supplied by the _______________.
AI Explanation
The correct answer is B) main and/or auxiliary condensate pump.
In a DC (direct-current) heater system, the cooling water to the vent condenser is supplied by the main and/or auxiliary condensate pump. The condensate pump circulates the condensed steam from the condenser back to the boiler, and this same water supply is used to cool the vent condenser.
The other options are incorrect because: A) the salt water circulator is used to cool the main condenser, not the vent condenser; C) the main feed pump supplies water to the boiler, not the vent condenser; and D) the feed booster pump increases the pressure of the feed water to the boiler, but does not supply cooling water to the vent condenser.
