EXAMPLE: Furnace wall thickness of 11 inches.

A furnace wall 11 inches thick falls within the dimensions listed in thefourth column. Thus the suffix “ 2W” applies. Continuing the example usedin STEP 1 the number is now RSA・1 OC-2W. (See Step 3.)

CATALOG UNDERSALES BULLETINSThe Selas RSA Refrak Screen Burner is a sealed­in tunnel burner with superior flame retention
andcombustion characteristics. The RSA ’ s large, per­forated refractory screen distributes the air/gas
fuel mixture uniformly within the tunnel, and as­sures complete combustion over an extremely wide
throttling range.

LOW OP巨RATING PRESSURE-The velocity andcooling action imparted by the long, narrow ports permit
low operating pressure with no flashback.

RSA Refrak Screen Burners are employed wher­ever sealed-in tunnel burners are required andwhere furnace temperatures do not exceed 2100 ° F(1150 ° C). (Use S-123 Refrak Screen Burners forhigher furnace temperatures; see Selas BulletinRS・2). Typical applications include: kilns for brickor clay products; and annealing, melting and heat­
treating furnaces for the metalworking industry.
RSA Refrak Screen Burners are designed to aper­
ate with fuel gas at mixture pressure up to 60
inches w.c. They are now available with various
automatic ignition and flame detection accessories
including interrupted pilot.

REFRACTORY CONSTRUCT旧N-AII parts subjectedto heat are made of accurately formed, prefired refrac­tory; they are durable and easy to clean.

ADVANTAGESCOMPLETE COMBUSTION-Uniform furnace atmo・
sphere is assured as all of the gas and air are burned atthe burner; tight furnace construction is possible.

EASY INSTALLATION-Conveniently sized burner
blocks are easily and quickly cemented into furnace
masonry.
EASY REPLACEMENT -Precision made standard re­fractory and metal parts facilitate burner change or re­placement without distu巾ing the burner block or furnacelining.

w旧E RANGE OF SIZES-Available in eight stand­ard burner sizes for capacities up to 4,000,000 Btu/hr.
(1,000,000 Kcal/hr.), and for wall thickness from 63/.iinches to 12γ2 inches.

W旧E OPERATING RANGE-Turn down in excess of
10:1 reduces the number of burners required and, there­fore, simplifies manifolding and control.

LOW TURBULENCE-Burner noise or “ rumble" isgreatly reduced with long port, refractory screen.

SUPERIOR FLAME RETENTION-High operatingpressures, without blow off, can be attained due to theself-piloting action of the many small flames.

SHORT FLAME-Long flame "tails ” and localized hot
spots are minimized; complete combustion takes placeat the burner.
