About this training
Fundamentals of Combustion is a 2-part course that provides the learner with the necessary underpinning knowledge for operating these technologies more confidently and optimising thermal efficiency. The learning is also helpful to maintaining environmental compliance throughout operational periods and to improving reliability and availability.
Module 2 builds on the learning from module 1 providing learners with the underpinning knowledge and scientific understanding to be able to achieve improved overall plant performance in terms of efficiency and environmental compliance.
What will I learn on the course?
• Understand the differences between elements, compounds, and mixtures
• Understand what happens during a combustion reaction and what affects combustion and thermal efficiency
• Understand the relationship between reactants and products
