Heating Systems Burners, Oil and Gas Ray Burner Co. Since 1872 1301 San Jose Avenue San Francisco 12, Calif. Atlantic Seaboard Division 629 Grove Street Jersey City 2, N. J. There is a RAY Burner for every Heating Purpose. RAY FORCED DRAFT PACKAGED BURNER Scotch Marine application A factory assembled unit readily applied to any type of boiler designed for forced draft operation. Fully automatic operation on oil, gas or combination gas-oil. The combination gas-oil unit includes a rotary oil burner, integrated ring type gas burner, secondary air control with a forced draft fan, windbox, refractory support ring, completely wired control cabinet and pre-piping completely, factory as sembled for quick and easy installation to the boiler. Oil components may be selected to. burn any grade of oil with the secondary air control providing increased efficiency even with the difficult-to-burn catalytic residual #6 fuel oils. sizes 3-5 to 10. From 90 to 750 developed output horsepower. RAY COMBINATION OIL-GAS BURNERS Type for water tube boilers ARC-1U Model SO for heavy oU and Low Pressure Gas Type PC for $2 oil or lighter and Low Pressure Gas ARC-MODEL 50. Consists of a rotary type oil burner of Ray conventional design coupled with a gas housing for low pressure gas, from 2 in. WC to 10 in. WC. The gas burner parts provide for the introduction of gas in a manner which fully utilizes the energy m the high pressure air supplied by the rotary burner fan. Gas and pri mary air are intimately combined, in two stages, before mixing with the secondary air which is introduced through a vaned annular opening concentric with the nozzle. Change-over requires less than one minute. Available to burn any grade of oil in 9 sizes with capacities to 31,500,000 Btu/hr. TYPE PC. Fully automatic combination gas-oil burner of the pressure atomizing type. Available in three sizes with capacities from 140,000 to 2,500,000 Btu/hr. New ignition system eliminates conventional gas pilot substituting XJ.L. approved system igniting main gas flame from momentary oil firing cycle. This constitutes a pre-purge of oil nozzle minimizing coking during extended gas firing seasons. Gas pilot avail able where local codes require. High speed 3450 rpm models available for forced draft operation. RAY DOMESTIC AND MARINE BURNERS RAY PRESSURE ATOMIZING OIL BURNERS. Fully automatic for %2 oil or lighter. 4 sizes with capacities from 1 to 18 gph. All types have intermittent or constant electric ignition, a-c or d-c. Stack switch control is standard, elec tronic flame safe-guard controls optional. High speed 3450 rpm models available for forced draft operation. Fully Automatic, Type Texted and approved Jot JP, St or liyhter oil U. S. Navy Service. 414 Heating Systems Burners Oil and Gas Ray Burner Co.

RAY HORIZONTAL ROTARY OIL BURNERS Type AR-m Size SO for No. 6 oil. Available in 10 sizes from 2 to 210 gph. Fully automatic. Fully Automatic Type AR-I34, for No. 5 oil. TypeBR-144, BeltDrive, Fully Automatic, Avail able in 8 sizes. Capacities from 2 to 110 gph. Type ARJP, Fully Au tomatic for heavy oil where gas for ignition not available. Built in fully automatic, semi-automatic and manual types; in sizes from 1 to 1000 Boiler hp; to burn all grades of fuel oil. Standard models include both direct and belt drives--the latter being recom mended for use .where other than 50 or 60 cycles a-c, or only d-c is available. Types for diesel electric or gas electric ignition; pump or gravity feeds. Direct drive types include a steam turbine driven model. Most fully automatic types for heavy oil incorporate the Ray Dual Pump and Res ervoir, with the Ray VISCOSITY Valve, a patented, exclusive feature which auto matically meters the correct amount of fuel at all times, regardless of changes in viscosity of the oil due to temperature variations. All larger sizes employ dual igni tion system, consisting of dual high-voltage transformers, dual electric ignitors and dual gas. valves. Fully automatic sizes 9 and 10 include as standard equipment elec tronic pilot and flame failure control. RAY INSHOT GAS BURNERS Multi-jet atmospheric type gas burners with high flexibility in nozzle number, arrangement and capacity, permitting high input ratings in limited space. For commercial and industrial application with natural or induced draft. Available Size 2, IG-29. in 36 different jet arrangements with capacities from 99 to 7512 cfh.
