BD First Class Boiler Attendant study plan

Map the normal operating sequence for a shell boiler from cold start to on-line, listing each step and the reason for its order

Write out the correct light-off, warm-up and pressure-raising procedure for a cold boiler, including air purge and warm-up firing rates

Identify the statutory duties of a first class attendant under provincial boiler legislation and note which records must be kept and for how long

Define the terms 'first class', 'second class', 'high pressure' and 'low pressure' as used in the applicable boiler regulation

Produce a one-page shutdown checklist distinguishing a controlled cooldown from an emergency stop

Explain the causes and correct response to low water level, high water level, flame failure and furnace puff-back

Sequence the actions for a boiler room emergency so the fuel is cut, air is purged and the condition is reported in the right order

Describe the hazards of priming, carryover and water hammer and state the corrective action for each

Draft a pre-shift safety walk-around that covers gauge glasses, safety valves, low water fuel cut-off, flame scanner and burner front

State the personal protective equipment and lockout/tagout steps required before opening a boiler or firing equipment

Classify firetube and watertube boilers by construction, and state the pressure and capacity range each suits

Sketch and label a longitudinal section of a firetube boiler and a watertube boiler, naming the drum, tubes, furnace, baffles and flue path

Explain the function of every required fitting: safety valve, safety relief valve, gauge glass, pressure gauge, low water fuel cut-off, feedwater check valve, main steam stop valve and blowdown valve

Distinguish between a fitting, a mounting and an accessory, and give three examples of each

Describe the layout and purpose of the superheater, economizer and air preheater in the gas path

Compare coal, oil and natural gas by heating value, storage requirement, handling hazard and combustion air demand

Explain the three T's of combustion and how excess air, stack temperature and draft each affect efficiency

Trace the combustion gas path and identify where carbon monoxide, soot and unburnt fuel indicate poor combustion

Describe how a flame scanner, modulating burner control and combustion analyser work together to hold safe firing

Calculate the approximate efficiency loss from a given stack temperature and excess air figure using a simple rule-of-thumb method

Explain how hardness, alkalinity, dissolved oxygen, silica and suspended solids each damage a boiler

Describe the purpose and chemistry of internal treatment for scale, corrosion and carryover control, and the role of blowdown in holding dissolved solids within limits

Trace the feedwater path from deaerator through feed pump, economizer and feedwater regulator to the boiler, naming each component's job

Explain the operation of a deaerator, a feedwater regulator and a steam header with its traps and separators

State the tests a first class attendant should be able to interpret: conductivity, pH, hardness and dissolved oxygen

Distinguish between an internal inspection and an external inspection, and list what each covers

Describe the correct procedure for testing a safety valve by hand and by accumulation test, and state the acceptance criteria

Explain hydrostatic testing: preparation, test pressure, hold time and what a pass or fail looks like

Describe how to test a low water fuel cut-off and a gauge glass, including the blowdown and refill sequence

Outline a preventive maintenance schedule for burners, feed pumps, safety valves, controls and water level devices

Summarize the inspection and certificate renewal cycle required by the boiler regulation, including who may inspect and when

State the rules on operator attendance, log books, accident reporting and notice of defects

Explain the legal and practical consequences of operating with a defective safety valve or an expired certificate

List the common causes of boiler accidents and the specific prevention measure for each

Describe the correct response to a tube failure, a furnace explosion and a fuel oil leak in the boiler room

Run through a full cold start, normal operation and controlled shutdown sequence without notes

Diagnose five given fault symptoms and state the likely cause and the safe corrective action for each

Interpret a set of gauge, draft, stack temperature and water test readings and state whether the boiler is running efficiently

Review all weak areas from earlier weeks and rewrite the notes for those topics in condensed form

Complete a timed practice paper under exam conditions and mark it against the reference material
