Question 281Steam Plants - Assistant Engineer

The correct answer is C) the accumulator. The gage glass on a coil-type auxiliary boiler is connected to the accumulator, which is a tank or chamber that helps maintain a constant water level in the boiler. The accumulator is designed to collect and store the water that circulates through the heating coils, ensuring a stable water supply to the boiler. The other answer choices are incorrect because: A) The heating coil inlet and outlet are not directly connected to the gage glass. B) The surge chamber is a separate component that handles pressure fluctuations, not the water level. D) The water softener is a separate component used to treat the boiler's water, not directly connected to the gage glass.
