Assembling the Dual Plasma Burner for Component Replacement with the

SCD

The following procedure can be used to assemble the Dual Plasma Burner for use with the SCD or for replacement of Burner components, such as ceramic tubes. Refer to Figure 1 on page 26 for proper part nomenclature.

1Slide the 0.066" internal diameter (I.D.) double taper ferrule onto the lower Burner tube. The tube should extend approximately 2 mm past the end of the ferrule.

2Insert the lower Burner tube and double taper ferrule into the Burner inlet fitting.

3Slide the 1/4" Burner adapter over the top of the lower Burner tube all the way down to the Burner inlet fitting and screw it onto the fitting finger-tight.

Figure 25 Ferrule Placement on Lower Burner Tube

4Slide a 1/4" Swagelok nut over the Burner adapter and then slide a 1/4" ferrule over the Burner adapter and position it into the 1/4" nut. Note: If a graphite ferrule is used, a small amount of shavings may be created and some graphite will be left on the tube surface; this is normal. Avoid allowing any shavings to fall inside a tube.

5Center the lower Burner tube so that it will slide into the tapered union. Insert the lower end of the tapered union fitting into the 1/4" Swagelok nut

and screw it on finger-tight. If necessary, the brazed H2 line can be gently bent out of the way, however, be careful not to stress the brazed (welded)

connection.

6Insert the large ceramic tube into the quartz heater assembly. Position a 1/4" ferrule (flat end butted up against the top of the swivel nut) onto the large ceramic tube. With the ferrule positioned against the swivel nut, approximately 0.5 cm of the large ceramic tube should extend outside of the nut. Insert the lower Burner tube into the center of the large ceramic tube and finger tighten the heater swivel nut onto the tapered union fitting.
