About this training
Increasing demand for energy and rising energy prices is placing pressure on UK thermal waste treatment plants, both private and public, to generate useful heat and/or power effectively and efficiently from non-recyclable and residual waste streams (including refuse derived fuels) without posing a risk to people or the environment.
This specialist e-learning course provides you with the opportunity to learn more about how flue gas conditioning and waste heat recovery boilers are used to increase efficiency and accomplish this goal. The course focuses on five key areas:
- Flue Gas Conditioning Techniques
- Principles of Waste Heat Transfer
- Waste Heat recovery boiler design
- Boiler safety and related regulations
- Waste Heat recovery in practice
What will I learn on the course?
The course aims to ensure delegates:
- Know the advantages of adopting waste heat boiler for cooling hot exhaust gases
- Know the mechanisms of heat transfer
- Know the differences between smoke tube boilers and water tube boilers
- Know how to navigate your way to appropriate information resources on boiler safety and appropriate regulations
- Know factors that can cause accelerated erosion and corrosion in boilers.
