At the nozzle, the oil is forced through a precisely calibrated orifice, creating a spray of microscopic droplets. Efficiency Rating Typical Era Impact 60-70% Pre-1970s.
Heat Exchanger Inspection Techniques Manual
Ignition Electrode: Creates the spark that initiates the combustion process. Draft Inducer/Blower: Manages airflow for efficient burning and expels exhaust.
The process begins when a thermostat signals a call for heat, activating the burner motor. Heat Exchanger: Transfers heat from the flames to the air without mixing them.
Effective Heat Exchanger Inspection Techniques for Optimal Furnace Performance
Simultaneously, a blower motor draws in air and forces it past a transformer that creates the ignition spark. Contemporary high-efficiency models, however, can achieve ratings exceeding 85%, and some condensing units approach 95%.
