Question 97Steam Plants - Assistant Engineer70% to pass
With the steam control valve wide open during normal operation, the rate of steam flow from the auxiliary exhaust steam line to the DC heater is actually a function of _______________.
AI Explanation
The correct answer is D) rate of condensation in the DC heater.
With the steam control valve wide open during normal operation, the rate of steam flow from the auxiliary exhaust steam line to the DC heater is determined by the rate of condensation within the DC heater. The steam flow rate is not affected by the rate of evaporation in the DC heater (A), the water level in the DC heater reservoir (B), or the spring pressure of the spray valves (C). The steam flow rate adjusts to match the rate at which the steam condenses within the DC heater, which is the correct explanation for the given scenario.
