Question 103Steam Plants - 1st Asst/Chief70% to pass
In most installations, the firing rate of a boiler using steam atomization is indicated by the _______________.
AI Explanation
You are correct, 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. This is because the fuel oil supply pressure directly determines the flow rate of the fuel oil being injected into the boiler, which in turn determines the firing rate of the boiler.
The other options are incorrect because they do not directly indicate the firing rate. The burner register opening (A) and the steam atomization temperature (D) do not directly affect the fuel oil flow rate. The fuel oil return pressure (C) indicates the backpressure in the fuel oil system, but does not directly reflect the firing rate.
