Question 333Steam Plants - Assistant Engineer70% to pass
In most installations, the firing rate of a boiler using steam atomization is indicated by the _______________.
AI Explanation
The correct answer is B) fuel oil supply pressure.
The firing rate of a boiler using steam atomization is indicated by the fuel oil supply pressure. The fuel oil supply pressure is directly proportional to the firing rate of the boiler, as it determines the amount of fuel oil being delivered to the burner. Higher fuel oil supply pressure corresponds to a higher firing rate, while lower pressure indicates a lower firing rate.
The other options are incorrect because they do not directly indicate the firing rate. The fuel oil return pressure (A) is not related to the firing rate, the burner register opening (C) controls the air-fuel ratio but not the firing rate, and the steam atomization temperature (D) is not a direct indicator of the firing rate.
