4. When an atomizer is removed for cleaning, be sure that thte manual oil valve at the lighter is closed to prevent the possibility of oil being discharged onto the burner platform.

5. Check all gaskets and joints.

6. Check 60 mesh filters in the fuel oil and purge air lines. When the pressure gauge on the control unit indicates less than normal oil or air pressure, the filters should be cleaned or replaced as required.

7. Adjust the flow control valves for the desired lighter travel speed.

8. The adjustable stops on the lighters must be adjusted to open the interlock valves.

9. All pressure switches are normally set to close at 70 psi which is the minimum recommended pressure.

10. The purge timer must be set to allow sufficient time to purge all oil from the oil lines between the control unit and the lighters. The correct time can be determined by observing the lighter flame during the purge period. Most of the oil has been purged when the flame goes out, but purge should be continued about 30 seconds beyond flame-out.

11. The cover on the electrical cabinet should be in place at all times, except for maintenance and adjustments. Otherwise, dust can prevent the electrical contacts from closing properly.

EMERGENCY STOP

If the lighters do not light within the normal 10 to 20 seconds after they are turned on, the oil and ignition transformers must be turned off and the lighters retracted without purging the oil lines and lighters. Operation of the various valves and switches is similar to the lighter retract sequence.

The ignition transformers and solenoid valves 8A, 8B, 8C and 8D are de-energized. Control air to valves 7A, 7B and 7C is vented, causing them to shift to their closed positions.

Pressure switch 9A and 9D open to indicate no oil pressure to the lighters and no purge air pressure.

Solenoid valve 8A is de-energized and shifts valve 41 (air cylinder control valve) to the retracted position. Air from valve 41 retracts the lighters. Pressure switch 9C opens when the lighters reach their retracted position and mechanical stops on the lighters open the retracted interlock valve. Air from the interlock valves close pressure switch 9B to indicate that the lighters are retracted.

ADJUSTMENTS

For proper operation of the lighters, the following checks and adjustments must be made:

1. Remove and clean electrode.

2. Set electrode spark gap at 1/8th inch.

3. Remove and clean atomizer cap and spray plate (clean with solvent,

Oil Purge

Solenoid 8B is energized (purge indicator light on) and solenoid valves *C and 8D are de-energized. Air from valve 8B shifts valve 7C (purge valve) to the open position. With solenoid valves 8C and 8D open to vent control air from valves 7A (oil on) and 7B (oil fill), both valves shift to the purge position. Oil flow is cut-off.

Purge air is admitted to the oil lines and lighters to purge them of oil. The purge timer must be set to allow sufficient time for this purge. Up to three minutes may be required to complete the purge. This time is factory set at one minute.

Pressure switch 9A close at 70 psi and the contacts on pressure switch 9D close indicating purge air is being admitted to the oil lines. Following the purge period, solenoid valves 8A, 8B and the ignition transformers are de-energized.

Retract

Valve 41 (air cylinder control valve) will shift to the retract position. Air passes from valve 41 to the air cylinders and retracts the lighters. The cylinders rate of travel can be controlled by adjusting the speed control valve on the exhaust side of the air cylinder. The exhaust air vents back through valve 41. Pressure switch 9C opens hen the lighters begin to retract.

When the lighters reach their retracted position, mechanical stops on the lighters open the retracted interlock valve. Pilot air from the interlock valve closes pressure switch 9B to indicate that the lighter is in the retracted position.

------------------------------------------------- 13 ------------------------------------------------------

#BoilerManual #Lighters #Section4 #Page12

Oil Fill

Since solenoid valve 8C has already been energized, pilot air will shift valve 7B (oil fill valve) to the firing position. The oil fill indicator is lit on the local control package. Oil flows from valve 7B through the check valve and orifice to the lighter. Flow though the orifice to empty piping is at a reduced rate. This slow opening action prevents tripping of other lighters (lost of oil pressure) which may be operating from the same main oil supply header.

Oil On

When the oil line to the lighter is full, pressure switch 9E closes, energizing solenoid 8D. The oil on indicating light will be lit on the control package. Pilot air from solenoid 8D shifts valve 7A (oil on valve) bringing the total oil supply to the lighter. When the oil pressure to the lighter reaches 70 psi, pressure switches 9A and 9D close to indicate oil supply to the lighters.

NORMAL SHUTDOWN

During a normal shutdown, the oil is turned off, the oil lines are purged with air, the ignition transformers are de-energized, and the lighters are retracted. Operation of the various valves and switches is as follows. Refer to Figures 8 and 9 for a schematic representation of each sequence.

3. OIL PURGE

During a normal shutdown of the ligher, all fuel oil is purged from the piping and atomizer to prevent oil from dripping into the burner or windbox. Purge air at 80-125 psi is admitted to the oil piping after the fuel oil valve is closed, but before the lighter is retracted and before the ignition transformer is de-energized. The purge should be continued until the lighter flame goes out. After the purge, the ignition transformer is de-energized and the lighter is retracted.

4. EMERGENCY STOP

If the lighter does not light within five seconds after its fuel oil valve is opened, if ignition is lost during operation, or if furnace conditions dictate that all fuel by tripped, the lighter fuel oil is turned off, the ignition transformer is de-energized, and the lighter is retracted.

LIGHT-OFF POSITION

Normally the interlocks are arranged so that certain requirements must be satisfied before the lighters can be started. These sequential requirements being:

1. Boiler not tripped.

2. Windbox/furnace delta-P is greater than 10 inches and less than 35 inches.

3. Boiler air flow is greater than 25%.

1. Boiler not tripped.

2. Windbox/furnace delta-P is greater than 10 inches and less than 35 inches.

3. Boiler air flow is greater than 25%.

after the fuel shutoff valve is closed. This purge air should be passed through a 60 mesh strainer, similar to the fuel oil strainer, to prevent plugging the atomizer with debris and scale from the purge air piping.

For rapid and complete oil purges, the fuel oil shutoff valve, purge air connection, and piping should be above the lighter. The total length of pipe to be purged should not exceed 50 feet. If piping and/or valves are below the lighter, the lowest point in the piping should not be more than 10 feet below the lighter and the total
length of piping to be purged should not exceed 25 feet.

OPERATION

The operator should be thoroughly familiar with the lighter, its controls, interlocks, main burners, and related equipment. Operation of the lighter in relation to furnace purging, air flow, and main fuel flow is described in the burner instructions. Normally, four operating conditions exist for the lighter:

1. LIGHT-OFF POSITION

.......... The lighter is moved to the light-off position by reversing the air pressure to the air piston. When the lighter is in the light-off (firing) position, the ignition transformer is energized and the fuel oil to the lighter is turned on. The ignition transformer is normally energized for as long as the fuel oil is being admitted to the lighter. The fuel oil valve should be opened slowly to prevent header pressure decay and possible loss of ignition on the other lighters supplied by the same header.

1. NORMAL SHUTDOWN

.......... When the lighter is not in use, it is retracted from the furnace to

The air cylinder operates on compressed air supplied at 80 - 125 psi. The air must be clean and dry to keep the cylinder functioning properly. Flow control valves are used to control the speed of the piston stroke. {A word about the air compressors used to supply this and workshop functions: Taking air from the atmosphere and compressing it will precipitate its moisture content and there are moisture traps located in various places along the compressed air pipes. When they malfunction, they're repaired or replaced.}

Other air valves are mechanically operated by the cylinder drives. The pressure signal from these valves are used for position indicators and interlocks. The oil valve will open only when the atomizer is fully inserted and will close when it is retracted, based on the signals through these air valves.

The oil spray is ignited by the high energy spark ignitor. Power to this ignitor is supplied from a transformer based on a pressure signal from the mechanical valves on the air cylinder drive. Electricity flows the length of the probe to the spark gap.

The 10,000 volt, 23 milliampere spark created across the 1/8 inch gap ignites the coal. The lighter can use Number 1 and 2 fuel oil. The fuel oil must be passed through a 60 mesh strainer and supplied to the atomizer at 150 to 250 psi.

The lighter capacity can be varied to some extent by varying the fuel oil supply pressure between150 and 250 psi. The oil capacity of the lighter is 900 lb/hr and requires a size 3820M mechanical sprayer plate.

In addition to cylinder drive air, the lighter requires seal and purge air supplies. The air supply to the lighter seal requires six SCFM of air suplied and a pressure of at least 2 inches of water greater than the windbox pressure. This seals the lighter assembly against dust or ash accumulations which could hinder lighter movement.

Purge air requires approximately 5.5 SCFM {Standard Cubic Feet per Minute} of air at 50 psi to purge fuel oil from the supply lines and atomizer when the lighter is removed from service. This prevents fuel oil from draining into the burner and windbox

Mark IV oil lighters

The lighter is an essential piece of equipment in firing any boiler. While its primary purpose is to provide the initial ignition of the coal when a cyclone is placed in service, it can also be used to stabilize ignition at low loads, to warm the furnace prior to placing the cyclone in service, and to sustain ignition for as long as possible when the burner is removed from service. The lighter must be properly maintained and cared for to ensure that it performs reliably when it is needed, and properly operated to help safeguard against furnace explosions.

It will be the purpose of this section to familiarize you with the components associated with the lighter and the lighter control unit. Also discussed will be the various modes of lighter operation and the recommended operating checks and adjustments which aid in the proper operation of the lighter.

DESCRIPTION AND PURPOSE

Your mechanical oil atomized lighter is equipped with an electrode for spark ignition, a piston and air cylinder for extending and retracting the atomizer and electrode, and flow control valves for controlling the speed of extending and retracting. Refer to Figure 1 for lighter components and their location.

The B&W spark igniter consists of a mounting sleeve assembly through thte cyclone front closure and neck tubes. The igniter is positioned at the secondary air inlet of the cyclone, Figure 2. When properly installed, the lighter flame will extend into the fuel/air mixture of the main burner at a point where ignition of the main fuel normally begins. The lighter is designed for lighting a main burner and for stabilizing ignition of that burner. The lighter is not intended to be used as a burner for carrying load. The lighter must be properly maintained and
