Question 94Steam Plants - Assistant Engineer

The correct answer is A) reserve feed tank. In a deaerating feed heater, a high water level will cause the automatic dump valve to drain the condensate to the reserve feed tank. This is done to prevent water from entering the boiler, which could lead to potential damage or operational issues. The reserve feed tank is designed to receive and store the excess condensate from the deaerating feed heater, maintaining the proper water level in the system. The other options are incorrect because the main condenser (B) and auxiliary condenser (C) are not the intended destinations for the condensate from a deaerating feed heater, and the atmospheric drain tank (D) is not the correct destination for this purpose.
