Pressure Atomizing Oil Burner Equipment and Systems – Other Components and Parts
Pre-cast, sectional, circular, high temperature refractory sections, made in a range of sizes and compositions, became widely used starting in the 1940’s for the construction of “fire boxes” [combustion chambers]. The firebox, holding a 2.600 degree F. flame in check, was a critical component, determining both system safety and performance, 2 sections, model 424, A P Green, Circa 1945.
Technical Significance:
With the evolution of the industry came pre-formed, sectional, circular refractory sections in a range of sizes, pre-shaped for certain firing rates and fire chambers
The evolution of pre-formed, sectional, circular refractory was hastened by the development of unitary, factory made and assembled warm air furnaces, winter air conditioners and hot water home heating boilers. Shipped to the job site this equipment came complete with oil burner, refractory and control system reedy for installation.
Industrial Significance:
With the evolution of unitary equipment for residential heating in Canada came generally higher levels of system performance, reliability and safety, with much of the guess work required with the conversion of hand fired wood and coal fired systems gone.
The significant developments in ceramics engineering, reflected in the refractory materials of the period, should not be understated, for they made possible the evolution of automatic home heating and its seminal contribution to life in Canada. An unobtrusive technology in the public eye, the accomplishments in ceramics engineering tend to get lost in the midst of the Gee-Whiz technological achievements in combustion and electric control engineering of the 1920’s and 30’s.
By the 1960’s much ceramic-based combustion chamber engineering would give way to light weight stainless steel configurations, considered preferable for the new world of unitary equipment, pre-tested and shipped to the job site ready for installation.
