Steam Boiler Operations

• Larger capacity steam boilers require continuous supervision due to the hazards they pose to public safety.
• Operators must attend to steam pressure, water level, and burner conditions with vigilance.

Daily Routine Activities

• Operators must perform several checks and functions every day, including:
  • Burner operation
  • Flue gas temperature
  • Steam pressure
  • Water level
  • Low water fuel cut-offs and float-type water level controls
  • Heat transfer
• Operator duties include:
  • Boiler water treatment tests
  • Feedwater treatment tests
  • Make-up water monitoring and tests
  • Continuous blowdown (CBD) adjustment
  • Bottom blowoff
  • Routine inspection
  • Housekeeping
  • Log book entry

Burner Operation and Flue Gas Temperature

• Burner operating principles are the same for hot water and steam boilers.
• Observe the condition of the burner flame:
  • Should be bright and symmetrical
  • Natural gas flame should be predominantly blue
  • Light fuel oil flame should be bright yellow
• Check the chimney for signs of smoking:
  • White plume indicates water vapor from combustion
  • Smoky flame indicates dirty burner nozzle, low fuel temperature, or incorrect fuel-air ratio

Steam Pressure

• Check the boiler steam pressure to maintain the boiler pressure at set point.
• The amount of fuel burned must correspond to the boiler load.
• The operator must be able to take over from the control system in case of failure.

Water Column and Gauge Glass

• Keep water in the boiler at the proper level.
• Never depend entirely on water level controls, emergency water feeders, or automatic alarms.
• The gauge glass is the primary indicator of boiler water level.
• Blow down the gauge glass and water column regularly to prevent sediment accumulation.

Water Treatment

• Take samples of boiler water, deaerated feedwater, and condensate.
• Perform required tests at intervals outlined in the water treatment program.
• Determine the amount of chemicals required to give the boilers and system the greatest protection.
• Monitor the external water treatment equipment.

Continuous Blowdown

• The continuous blowdown (CBD) should be opened just enough to keep the concentration of dissolved and suspended solids below the maximum allowed.
• Record the CBD setting and the boiler water conductivity in the daily log.

Inspection and Auxiliary Equipment

• Make a full inspection of the boiler to check for signs of leakage.
• Determine the cause of any unusual noises or conditions.
• Check the operation of auxiliary equipment in the boiler room, including:
  • Feedwater, condensate, and vacuum pumps
  • Fuel pump and fuel level in the tank (for oil-fired boilers)

Housekeeping and Boiler Log

• Keep the boiler room and equipment clean.
• Maintain the Boiler Room Log to record:
  • Each test performed, time, and result
  • Each condition observed
  • Each adverse condition and steps taken to address it
  • Sign and date each entry

Make-Up Water

• Use every practical means to exclude oxygen from the boiler water.
• Monitor the make-up water flow and calculate the percentage of make-up water used.
• Unexplained increases in make-up water indicate an abnormal system water loss.
• Feed make-up water into the condensate tank instead of directly into the boiler to reduce oxygen intake.
