Boiler Engineer Course

Lesson 1 • Introduction to Boiler Systems

Covers the purpose, classification, and industrial applications of boilers. Provides context for all subsequent technical content in the course.

Lesson 2 • Boiler Components and Assemblies

Identifies and describes all major boiler components and their functional roles. Builds the vocabulary needed for maintenance and operational tasks.

Lesson 3 • Thermodynamic Principles for Boilers

Introduces heat transfer, energy conversion, and steam properties essential to boiler operation. Connects physics fundamentals to practical boiler operation.

Lesson 1 • Combustion Chemistry Essentials

Covers oxidation reactions, stoichiometry, and combustion products for common boiler fuels. Provides the chemical basis for optimising burner performance.

Lesson 2 • Combustion Efficiency and Optimisation

Introduces flue gas analysis, stack loss calculations, and tuning procedures. Directly supports fuel cost reduction and emissions compliance.

Lesson 3 • Burner Design and Operation

Describes burner types, atomisation methods, and flame stability principles. Connects burner selection to fuel type and boiler design.

Lesson 4 • Fuel Types and Properties

Examines natural gas, fuel oil, coal, and biomass as boiler fuels. Compares heating values, handling requirements, and combustion characteristics.

Lesson 1 • Internal Chemical Treatment Programmes

Explains oxygen scavengers, scale inhibitors, and sludge conditioners added to boiler water. Connects chemical dosing to boiler longevity and efficiency.

Lesson 2 • Blowdown Procedures and Control

Teaches surface and bottom blowdown techniques to manage dissolved and suspended solids. Balances water quality with heat and water conservation.

Lesson 3 • Corrosion and Scale Identification

Identifies types of boiler corrosion and scale deposits and their root causes. Enables engineers to diagnose water treatment failures from physical evidence.

Lesson 4 • Feedwater Pretreatment Systems

Covers softening, deaeration, and filtration processes used before water enters the boiler. Prevents scale and corrosion at the source.

Lesson 1 • Safety Interlocks and Burner Management

Covers burner management systems, flame safeguard relays, and safety interlock logic. These systems prevent unsafe startup and operation conditions.

Lesson 2 • Combustion Control Systems

Describes parallel positioning, cross-limiting, and fully metered combustion control strategies. Ensures safe air-fuel ratio management across all firing rates.

Lesson 3 • Flow and Level Measurement

Explains feedwater flow meters, steam flow measurement, and drum level sensing. Accurate flow and level data drive feedwater control and safety systems.

Lesson 4 • Pressure and Temperature Measurement

Covers gauges, transmitters, and thermocouples used to monitor boiler operating conditions. Accurate measurement is the foundation of safe and efficient control.

Lesson 1 • Safety Valve Testing and Maintenance

Describes manual lift testing, as-found testing, and replacement criteria for safety valves. Ensures valves will open reliably when needed.

Lesson 2 • Low-Water Fuel Cutoff Devices

Explains float, probe, and differential pressure low-water cutoff technologies and their testing. Low-water conditions are a leading cause of catastrophic boiler failure.

Lesson 3 • Regulatory Compliance and Inspection

Introduces boiler inspection requirements, authorised inspector roles, and documentation obligations. Compliance protects personnel and maintains operating certificates.

Lesson 4 • Safety Valve Principles and Selection

Covers spring-loaded safety valve design, set pressure, blowdown, and capacity requirements. Safety valves are the last line of defence against overpressure.

Lesson 1 • Normal Operating Duties

Defines routine monitoring tasks, log-keeping, and adjustments during steady-state operation. Builds the discipline required for consistent, safe boiler management.

Lesson 2 • Normal and Emergency Shutdown

Explains planned shutdown sequences and emergency trip responses for various fault conditions. Correct shutdown prevents equipment damage and personnel hazards.

Lesson 3 • Pre-Startup Inspection Checklist

Establishes systematic checks of water level, valves, instruments, and fuel supply before firing. Prevents unsafe conditions from being carried into operation.

Lesson 4 • Operating Limits and Alarm Response

Defines normal operating ranges and the correct response to high-priority alarms. Connects alarm management to safe operating envelope maintenance.

Lesson 1 • Tube Cleaning and Inspection

Covers mechanical and chemical tube cleaning methods and visual inspection techniques. Clean tubes maintain heat transfer efficiency and prevent tube failures.

Lesson 2 • Boiler Layup and Preservation

Covers wet and dry layup procedures to protect boiler internals during extended outages. Proper preservation prevents corrosion damage during idle periods.

Lesson 3 • Refractory and Insulation Maintenance

Explains refractory inspection, repair, and replacement for furnace walls and burner quarls. Damaged refractory causes heat loss and structural risk.

Lesson 4 • Non-Destructive Testing Methods

Introduces ultrasonic, radiographic, magnetic particle, and dye penetrant testing for pressure parts. NDT detects flaws before they cause failures.

Lesson 1 • Steam System Optimisation

Addresses steam trap management, distribution losses, and pressure optimisation across the steam system. System-wide efficiency depends on minimising losses beyond the boiler.

Lesson 2 • Heat Balance and Efficiency Calculations

Teaches input-output and heat loss methods for calculating boiler efficiency. Quantitative analysis drives targeted improvement actions.

Lesson 3 • Waste Heat Recovery Systems

Covers economisers, air preheaters, and condensate recovery to capture otherwise lost energy. Each system reduces fuel consumption and operating costs.

Lesson 4 • Energy Auditing for Boiler Plants

Introduces data collection, baseline establishment, and opportunity identification in a boiler plant energy audit. Audits provide the evidence base for capital investment decisions.
