PHOENIX Talon - Operation and Service Manual

To Remove the Oil Gun Assembly, use the following steps:

1. Shut down the burner, and de-energize the burner compressed air system.

WARNING:

Lock-out the plant power, before working on the burner.

2. Shut off the manual oil ball valve on the burner oil train.

3. If heated heavy oil is being used, allow enough time for the oil in the piping to cool.

4. Remove the four nuts holding the Oil Gun/Pilot Assembly onto the burner/blower.

5. Pull out the Oil Gun/Pilot Assembly from the burner/blower body.

6. Make a note of the initial position of the oil nozzle.

7. Contact ASTEC Burner Systems Group for any questions about proper positioning.

8. Once the proper positioning of the Oil Gun/Pilot Assembly is completed:

a. Re-tighten the set screws of the set collars on the mounting plate of the Oil Gun/Pilot Assembly.

b. Install the Oil Atomizer Assembly in the burner/blower with the four nuts.

Compressed Air Train

1. The PHOENIX TALON uses compressed air for atomizing fuel oil.

2. Compressed air is supplied to the inlet of the compressed air train.

3. Size compressed air feed line according to “Recommended Compressed Air Pipe” Table – 8. (These

sizes will result in minimum pressure drop for proper oil atomization.)

4. See drawing for location of inlet pipe.

5. The compressed air train includes: a manual shutoff valve, “Y” strainer, Low compressed air switch,

pressure regulator, pressure gauge, compressed air solenoid and a flexible hose. (See Illustration -

11), this is a general arrangement. Each burner has its own drawings in the burner junction panel.

(See Burner Performance Data Sheets.)

6. Adjust the low compressed air pressure switch to just slightly under the recommended air pressure.

7. Compressed air pressure is adjusted by the “tee” handle on top of the pressure regulator.

8. Set the compressed air pressure to the pressure recommended (See Burner Performance Data

Sheets.)

9. The low, low compressed air switch is factory set at 60PSIG and is not adjustable. (See Illustration -
