70% to passCooling water to the vent condenser in a DC heater is supplied by the _______________.
Asalt water circulator
Bmain and/or auxiliary condensate pump
Cfeed booster pump
Dmain feed pump
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 main condenser back to the boiler, and a portion of this condensate is used to cool the vent condenser. The other options are incorrect because: A) the salt water circulator supplies cooling water to the main condenser, not the vent condenser; C) the feed booster pump supplies water to the boiler, not the vent condenser; and D) the main feed pump also supplies water to the boiler, not the vent condenser.
