Experiment with ordinary lighted candle showing the importance of combustion space in a heating boiler.
A thimble placed over wick extinguishes flame immediately.
Small glass placed over flame causes it to die down. Minimum amount of heat given off
Large water glass permits freer combustion but causes smoke.
Large combustion space provided by placing pail over flame
Permits maximum combus
tion. Candle burnes brightly, generating heat without smoke.
GREATER
Combustion Space
Greater combustion space is one of the factors responsible for the
remarkable efficiency of Pacific boilers.
Observe the illustrations at the left. They explain why maximum combustion space is so vital to satisfactory boiler performance.
The large illustration (showing Ford car standing in fire box of a Pacific Boiler) gives some idea of the tremendous combustion space as compared with the complete boiler. The result is maximum heat generated from fuel consumed—real heating economy.
The firebox in all Pacific Boilers extends full length of boiler, affording the greatest possible combustion space and direct heating surface.
This is only one of many Pacific features. Let us send you complete information.
