Lesson 3 • Steam Flow and Pressure Drop

Analyses velocity, flow rate, and pressure losses in steam distribution lines. Prepares students to size pipework and minimise energy losses in steam networks.

Lesson 4 • Phase Changes of Water

Traces water from subcooled liquid through saturation to superheated vapour. Builds the phase-change foundation needed to interpret steam table data accurately.

Lesson 1 • Key Boiler Components

Identifies drums, headers, economisers, superheaters, and air preheaters and their roles. Provides the component vocabulary needed for maintenance and operational discussions.

Lesson 2 • Specialty and Package Boilers

Covers electric, waste-heat, and packaged boiler designs for niche applications. Broadens selection knowledge for facilities with unconventional heat sources.

Lesson 3 • Boiler Fittings and Accessories

Reviews safety valves, water gauges, pressure gauges, and feedwater regulators. Ensures students can locate and interpret critical safety and control devices.

Lesson 4 • Water-Tube Boiler Design

Examines drum-and-header construction, circulation patterns, and high-pressure capability. Explains why water-tube designs dominate large-scale power generation.

Lesson 1 • Flue Gas Analysis and Losses

Uses Orsat and electronic analysers to measure CO2, O2, and CO in flue gas. Enables students to diagnose combustion problems and quantify stack heat losses.

Lesson 2 • Combustion Chemistry Basics

Covers stoichiometric reactions for natural gas, oil, and coal combustion. Provides the chemical foundation for air-fuel ratio calculations and emissions analysis.

Lesson 3 • Fuel Types and Properties

Compares natural gas, fuel oil, coal, and biomass by energy content and handling needs. Guides fuel selection decisions based on availability, cost, and emissions.

Lesson 4 • Burner Types and Operation

Examines gas, oil, and combination burners including atomisation and flame stability. Connects burner selection and adjustment to reliable, efficient boiler firing.

Lesson 1 • Startup and Shutdown Procedures

Details pre-startup checks, light-off sequences, and controlled shutdown steps. Establishes safe operating habits that prevent thermal shock and equipment damage.

Lesson 2 • Water Level Control

Explains single- and three-element feedwater control and low-water hazards. Directly addresses the most common cause of boiler incidents and failures.

Lesson 3 • Boiler Instrumentation and Alarms

Identifies key sensors, transmitters, and alarm setpoints used in boiler control panels. Enables students to interpret readings and act on alarm conditions promptly.

Lesson 4 • Automated Safety Systems

Reviews burner management systems, interlocks, and safety instrumented functions. Ensures students understand the layers of protection that prevent catastrophic failures.

Lesson 1 • Corrosion, Scale, and Deposits

Identifies oxygen pitting, caustic gouging, and scale as primary boiler damage mechanisms. Enables students to diagnose water-side problems from inspection findings.

Lesson 2 • Internal Chemical Treatment

Examines phosphate, polymer, and oxygen scavenger programmes applied inside the boiler. Maintains clean heat transfer surfaces and protects metal from corrosion.

Lesson 3 • Water Quality Parameters

Defines hardness, alkalinity, dissolved oxygen, and total dissolved solids as key water quality metrics. Establishes the measurement baseline for all treatment decisions.

Lesson 4 • Blowdown Control and Recovery

Explains continuous and intermittent blowdown to control dissolved solids concentration. Connects blowdown management to water conservation and heat recovery.

Lesson 1 • Regulatory Compliance and Codes

Surveys pressure vessel design standards, inspection requirements, and operator certification rules. Ensures students understand the compliance framework governing boiler operation.

Lesson 2 • Tube Inspection and Repair

Covers visual, ultrasonic, and eddy-current methods for detecting tube defects. Prepares students to assess tube condition and make informed repair or replacement decisions.

Lesson 3 • Preventive Maintenance Programmes

Structures daily, monthly, and annual maintenance tasks for boiler reliability. Reduces unplanned downtime and extends equipment service life through systematic care.

Lesson 4 • Boiler Safety Hazards and Risk Control

Identifies explosion, scalding, and toxic gas hazards and the controls that mitigate them. Builds a safety-first mindset grounded in hazard recognition and risk reduction.
