Pressure Atomizing Oil Burner Equipment and Systems – Fuel Flow and Combustion Controls
A 1920’s automated combustion controller for Canadian oil fired, home heating systems, with oil pressure actuated, pancake style bellows safety switch, electric thermal safety lock-out with manual reset and flapper valve actuated mercury bulb switch, enclosed in stylish, heavy cast steel enclosure with highly decorated cover plate, Hart Oil Heat, Preferred Oil burners Inc., Circa 1929.
Features:
– high style, painted stencilled cover plate in red, gold and black
– Original wiring harness
– Original oil piping connectors
Technical Significance:
– Representative of the earliest automatic combustion control technology for oil fired domestic heating systems marketed in Canada
– Characteristic of a period of embryonic technological development in any field, this automated combustion controller and safety switch further demonstrates the array of mechanisms, new and novel being experimented with. From the perspective of the early 21st century, without the benefit of documentation or schematic diagram, it is not at all clear even how the various interacting and mutually supporting component parts of this panel operated to variously provide the required level of automation and safety protection required for public comfort and safety.
– Representative, of the earliest complex systems introduced into the Canadian home. See Note #1
