HVAC Oil Burner Practice Test

The pressure rating for oil burner nozzles is typically around 100 psi. This is the standard pressure at which oil is delivered to the nozzle for effective atomization and combustion. At this pressure, the fuel oil is dispersed into fine droplets, which is crucial for achieving efficient combustion and optimal performance of the oil burner.

Having the correct pressure is vital, as it impacts the burner's efficiency, emissions, and overall functionality. If the pressure were set too low, it could lead to poor atomization, resulting in incomplete combustion and potential soot buildup. Conversely, excessively high pressure could cause damage to the nozzle or lead to other operational issues. Thus, 100 psi serves as a balanced threshold for ensuring that the burner operates effectively and within manufacturer specifications.
