MT Boiler Operator study plan

Label the major pressure-boundary components of fire-tube and water-tube boilers on a blank diagram from memory

Explain how shell thickness, tube sheet design, and staybolt spacing relate to maximum allowable working pressure

Distinguish between fireside and waterside surfaces and predict where thermal stress concentrates during heat-up

Identify at least 10 common boiler fittings (safety valve, gauge glass, try cocks, blowdown valves, low-water cutout) and state the function of each

Trace the steam and water path through a boiler system and place each accessory (feedwater pump, economizer, air preheater, superheater, separator) in correct sequence

Describe the operating principle and failure mode of safety valves, relief valves, and low-water fuel cutoffs

Calculate the required relieving capacity check for a safety valve given boiler capacity figures

Explain how gauge glasses, try cocks, and pressure gauges are tested and what a false water level indicates

Write the combustion equation for common fuels and calculate theoretical air requirements for natural gas and No. 2 oil

Differentiate the three T's of combustion and diagnose a smoking stack or high CO condition from given flue gas readings

Sequence the burner light-off, flame-safeguard proving, and shutdown steps for a typical packaged burner

Interpret excess air, O2, and CO2 readings and state acceptable operating ranges

Diagram a feedwater system from DA tank through pumps to the boiler and identify each control loop

Explain the causes and prevention of scale, sludge, carryover, and caustic embrittlement

Perform a blowdown and chemical dosage calculation given boiler capacity and makeup water quality

Describe feedwater pump types, NPSH concerns, and symptoms of cavitation

Write out cold-start, warm-start, and normal shutdown checklists from memory in correct order

Explain the purpose of warm-up, slow-roll, and controlled cool-down and the damage caused by skipping each

Demonstrate the correct response to a low-water condition and to a high-water condition, including when to secure the burner

Predict what happens to drum level, steam pressure, and stack temperature during a rapid load increase

Build a preventive maintenance schedule covering daily, weekly, monthly, and annual tasks for a packaged boiler

Describe hydrostatic test procedure, pressure limits, and inspection points for tube sheets, staybolts, and refractory

Explain safety valve pop testing, gag removal, and recordkeeping requirements

Diagnose common faults (short cycling, water hammer, flame failure, high stack temp) from symptom lists

Summarize the scope of ASME Boiler and Pressure Vessel Code Sections I and IV and where each applies

State the inspection and certificate renewal intervals and who is authorized to inspect under state boiler law

Identify operator licensing, log-keeping, and reporting obligations for the jurisdiction you work in

List the required markings on a boiler nameplate and explain what each stamp means

Rank boiler hazards by severity and describe the immediate response to a furnace explosion, tube rupture, and low-water trip

Explain lockout/tagout, confined space entry, and PPE requirements for boiler room work

Complete timed mixed-domain practice sets and review every missed item to root cause

Re-derive the three facts you most often forget from Domains 1, 2, and 5
