Practicals

60 hours of practicals To be conducted online or on-campus or in-house
Overview

Hands-on practicals are essential for developing competence in boiler operation, safety procedures, and troubleshooting. Learners will engage in simulated startup/shutdown sequences, perform water chemistry tests, and practice emergency response in a controlled environment, ensuring they can apply theoretical knowledge to real-world scenarios.

Practical Activities
  • Boiler Startup and Shutdown Simulation — Learners operate a boiler simulator to execute complete startup and shutdown procedures, including pre-start checks, purge, ignition, load changes, and isolation. (16h)
  • Water Chemistry Testing and Treatment — Learners collect feedwater and boiler water samples, perform chemical tests (pH, conductivity, hardness, phosphate), and adjust chemical dosing accordingly. (12h)
  • Combustion Tuning and Efficiency Measurement — Learners use flue gas analyzers to measure O2, CO, and temperature, adjust air-fuel ratio, and calculate boiler efficiency using direct and indirect methods. (12h)
  • Emergency Response and Safety Drills — Learners participate in simulated emergencies (tube rupture, flame failure, high pressure) and practice emergency shutdown, evacuation, and use of firefighting equipment. (12h)
  • Maintenance Inspection and Condition Monitoring — Learners inspect boiler components (tubes, refractory, valves) using visual and NDT techniques, and perform condition monitoring using vibration and thermography tools. (8h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total
Component Out of Weight
Practical Assignments (rubric-scored) 100% 30%
Daily Average (multiple choice) 100% 20%
Final Test (multi-answer multiple choice) 100% 50%
Final Total 100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

Certificate of Completion
