Course Overview
This three-week online course covers the technology, operational issues and strategic decisions involved in firing cement kilns with alternative fuels. It follows the implementation journey from fuel preparation and first introduction through plant modifications, higher substitution rates and the resulting impacts across the kiln system.
Across 12 technical lectures, seven applied exercises and three examinations, participants examine processing depth, bypass requirements, combustion, refractory linings, emissions, ash incorporation, clinker quality, reliability, energy consumption and productivity. Downloadable articles, presentations and lecture handouts support continued learning.

Industry Feedback
The sequence from fuel preparation to plant modifications helped us prioritise the next stage of our substitution programme.
Useful guidance on balancing higher alternative-fuel rates with flame shape and kiln stability.
The course gave a clear explanation of how fuel chemistry can change coating behaviour and lining risk.
A practical overview of the emissions and ash-quality questions that must be addressed before increasing TSR.
FAQ
How is AFM01 delivered?
The course is delivered online over three weeks, allowing participants to study flexibly at work or at home.
Does the course cover plant modifications?
Yes. It examines receiving and preparation systems, deeper processing, firing-system changes and the circumstances that may require an alkali bypass.
Are clinker quality and emissions included?
Yes. Dedicated sessions address flame and clinker quality, atmospheric emissions, ash incorporation and exotic species from alternative fuels.
How much study time is required?
Participants should allow around five or more hours per week, plus additional private reading and study time.
Are exercises and assessments included?
Seven practical exercises relate the material to participants' own plants, while three examinations support certification.
What learning materials are provided?
Downloadable lecture handouts, articles, presentations and supporting reading material are provided for the training record.
