ME Boiler Operator study plan

Draw and label, from memory, the major pressure parts of both a fire-tube and a water-tube boiler, then check your drawing against a reference text and correct errors in a different color

Explain in writing the difference in scope between the ASME power boiler code and the heating boiler code, and list three fittings required on each type

Describe the function of the safety valve, safety relief valve, steam gauge, water column, and low-water cutoff, and state what each protects against

Identify the required markings and nameplate data on a boiler and explain why each item matters to an operator

Trace a control circuit from memory: list the components between the low-water cutoff and the burner, and state what happens on a low-water trip

Compare the operating principles of the three common level-indicating methods and explain which failure modes each cannot detect

Define the terms setpoint, differential, proportional band, and deadband, and give one boiler example of each

Describe the purpose and testing method for the high-pressure limit control, the flame safeguard, and the low-water fuel cutoff

List the four requirements for complete combustion and explain how a change in each one shifts the flue gas readings

Compare the properties, storage, and handling hazards of the fuel types covered by your license class

Explain the purpose of excess air, and interpret a supplied set of flue gas oxygen and stack temperature readings to identify a likely fault

Describe the startup sequence of a burner from prepurge through main flame and the interlocks that must prove before each step

Sequence a cold startup of a boiler from pre-start inspection through placing it on line, listing the check at each step

Sequence a normal shutdown and an emergency shutdown, and state four conditions that require immediate emergency action

Demonstrate, in writing, the correct procedure and frequency for a low-water cutoff blowdown and a gauge glass blowdown

Describe how to bring a boiler on line in parallel with another and how to prevent carryover during that transition

Explain the operator actions and the correct order of response during low water, high water, flame failure, and high stack temperature events

Describe routine log-round readings and what an abnormal trend in each would indicate

Outline the procedure for testing a safety valve, a gauge glass, and a water column on a scheduled basis

Explain the correct way to take a boiler out of service for a short layup and for an extended layup

Explain the causes and prevention of scale, sludge, carryover, caustic embrittlement, and oxygen pitting, and match each to its treatment method

Describe the purpose and correct performance of bottom blowdown and continuous blowdown, including frequency and duration

Sequence an annual internal inspection from cool-down and preparation through reassembly, naming the operator's duties at each stage

Interpret a sample water test report and state the corrective action for each out-of-range result

State the operator licensing or certification requirements, including class definitions and any hour or experience thresholds, as set out in the Maine statute and rules assigned to you

Identify the inspection intervals, notification duties, and recordkeeping obligations imposed on owners and operators

List the operator's responsibilities when a boiler fails inspection or is ordered out of service

Review all safety device definitions from week 2 and correct any errors found in your earlier notes

Complete two full-length timed practice exams under exam conditions and score each section separately

Rank your six domain scores from weakest to strongest and re-study the two weakest for at least two hours each

Re-derive from memory the ten facts you most often missed and state each in your own words

Rehearse the startup, shutdown, and emergency sequences one final time without notes
