70% to passWhich of the following statements describes how the fuel oil enters the whirling chambers of the sprayer plates used in an auxiliary boiler return flow fuel oil system?
AThrough the outer barrel tube.
BThrough the sprayer plate drilled passages.
CThrough tangential slots in the sprayer plate.
DThrough baffles in the orifice plate.
AI Explanation
The correct answer is C) Through tangential slots in the sprayer plate. In an auxiliary boiler return flow fuel oil system, the fuel oil enters the whirling chambers of the sprayer plates through tangential slots in the sprayer plate. This creates a swirling motion that atomizes the fuel, allowing for more efficient combustion in the boiler. The other options are incorrect because: A) The fuel oil does not enter through the outer barrel tube. B) The fuel oil does not enter directly through the sprayer plate drilled passages. D) There are no baffles in the orifice plate that the fuel oil passes through.
