Burners, Oil Petroleum Heat & Power Company Makers of Oil Burners Since 1903 Boston PetrO DOMESTIC AND INDUSTRIAL OIL BURNERS Main Office--511 Fifth Avenue, New York, N. Y. Factory--110 Davenport Street, Stamford. Conn. San Francisco Branch Offices at Seattle Providence Los Angeles National Sales and Service Organisation Portland, Ore. PetrO Burners are all of the mechanical atom izing type and are built in such a number of models and sizes as to cover the heating field from the smallest residence to the largest com mercial or industrial heating plant. PetrO Burners are adaptable to any standard type of boiler or heater and can handle from a small heating load of 200 sq. ft. of steam radiation to 375 b.hp. with one burner. DOMESTIC BURNERS PetrO Domestic Burners are of the air turbine driven rotary cup type and are fully automatic and of the intermittent firing type. Stand ard Minneapolis-Honeywell con trols are used throughout. PetrO Domestic Burners are designed to burn commercial fuel oils having a gravity, of not less than 24 degrees Baume and a viscosity of not more than 50 seconds Saybolt Universal at 100 deg. fahr, Ignition is accom plished by means of either an electric spark or by means of a gaselectric type of ignition. The PetrO Burner is designed and built to operate with a mini mum of mechanical and combustion sound. It consists essentially of a centrifugal fan constructed with a shrouded aluminum runner, com pletely balanced and housed in a cast aluminum fan case. Mounted on the fan case and direct con nected to the fan runner is an electric motor. Also driven from the motor shaft either through reduction gearing or by direct con nection is a rotary gear oil pump. This assembly is mounted on a base built of grey cast iron in which is built a float chamber. Inserted through the base directly under the fan outlet is the burner gun, the forward end of which terminates in the air register which is installed flush with the boiler ashpit opening. The gun comprises the atomizing 588 Petroleum Heat & Power Company. Burners, Oil OIL BURNERS cup which rotates in ball bearings, oil connection from float chamber to atomizing cup, lubricating device for ball bearings and air connection for conveying air from fan through the cup turbine and past vanes for mixing the air with the atomized oil in the combustion chamber. Oil is drawn from the storage tank by the pump through a brass suction line and delivered into the float chamber where a constant level of oil is maintained. The pressure of the fan is communicated to the float chamber and acts to lift, the oil to the atomizing cup. The air is delivered past the turbine blades of the cup for atomizing the oil and finally into the com bustion chamber for supporting combustion. The standard installation in cludes a thermostat for controlling building temperature, a combustion safety control and a boiler, or furnace control for. limiting tem-. perature or pressure conditions at the boiler or furnace. Service hot water may be heated from the main heating boiler through standard indirect heaters during both summer and winter. ln)[p-|, Domestic Oil Burners are manufactured `*"*L--in the following models and capacities: Burner Model LD-00 LD-0 LD-K LD-2 LD-3 LD-4 Gallons of Oil per Hour y. toi'/2 Vl to 2'h 2i/2 to 5 5 to 10 10 to 20 20 to 42 Gas-electric Ignition only.
