Fundamentals of Combustion (Module 2)

Build advanced knowledge to optimise thermal waste treatment performance

Thermal waste treatment plants play a critical role in managing non-recyclable and residual waste by converting materials such as refuse-derived fuel (RDF) into valuable heat and power. However, achieving optimal performance requires a deeper understanding of combustion science and how it applies in practice.

This two-part course developed by E-Tech Learning Ltd provides the technical knowledge needed to operate thermal treatment systems with confidence, improving efficiency, maintaining environmental compliance, and enhancing plant reliability.

About this course

Module 2 builds on the fundamentals introduced in Module 1, advancing your understanding of combustion processes and system behaviour. You’ll gain deeper insight into how to optimise performance, manage emissions, and drive more efficient, compliant operations.

Understanding combustion chemistry
Develop a clear understanding of elements, compounds, mixtures, and how they interact during combustion reactions.

How combustion works
Learn what happens during combustion, including the relationship between reactants and products, and the role of molecular bonds and forces.

Energy and reaction types
Understand the difference between exothermic and endothermic reactions and how energy is released or absorbed.

Applying combustion principles
Build practical skills in interpreting basic equilibrium equations and analysing combustion processes.

Efficiency and performance
Understand the difference between combustion efficiency and thermal efficiency, and how they impact plant performance.

Flue gas analysis
Learn how to calculate and interpret the relative percentages of excess oxygen, CO₂, and other gases in exhaust emissions.

This course is suitable for anyone looking to deepen their technical understanding of combustion and optimise performance in thermal waste treatment facilities.

It is particularly relevant for:

  • Plant operators
  • Supervisors and operational leads
  • Engineers working with thermal treatment systems
  • Technically Competent Managers (TCMs)
  • Consultants advising on thermal processes and compliance
  • Local authority professionals involved in waste infrastructure
  • Regulators overseeing facility performance and compliance
  • Students and new entrants developing knowledge of thermal treatment technologies

Whether you are aiming to improve plant performance, strengthen compliance, or build advanced technical expertise, this module will help you apply combustion science to real-world operational challenges.
