OPERATION 1. The steam supply pressure ( P3 ) need not be regulated as long as it will not drop below 100 psi. Regulator ( C ) will adjust as necessary. 2. Emulsion pressure readings at ( P10 ) are only approximate. This pressure will usually be about 2⁄3 of the steam pressure at ( P9 ).
STARTUP 1. With oil valve ( D ) closed and no pressure at ( P5 ), adjust steam regulator ( C ) so that ( P6 ) reads 10 psi.
2. Light the pilot or provide some other satisfactory source of ignition.
3. Open the main oil valve and oil valves ( D ) and ( H ).
3. Burner turndowns in excess of 4 to 1 may result in loss of fuel to one or more burners in a zone due to unbalanced flow.
4. Open oil valve ( E ) to light the burner. This valve should be left wide open except when it is necessary to balance burners in a zone.
4. Changes in the oil supply pressure ( P2 ) may cause the actual operating pressures to deviate from the typical pressures shown above.
5. Slowly drive the burner to high fire, adjusting oil valve ( H ) to maintain a satisfactory flame.
6. At high fire, adjust valve ( H ) so that ( P5 ) reads 70 psi.
WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
