Calorimetry and Dust Explosibility Testing
Commissioning the right test, and reading the report you get back
A practical course for engineers who specify laboratory testing and then have to interpret it. Covers what each calorimetric and explosibility test measures, what it assumes, the sample condition that must be right for the result to mean anything, and the common misreadings of test reports.
This course sits alongside our Calorimetry and Dust Explosibility consulting work, so what is taught is what we do.
Who should attend
Course content
Every module is taught with worked examples and exercises drawn from real plant, and adapted to your own process where the course runs in house.
Thermal stability and reaction testing
- Differential scanning calorimetry as a screening tool and its blind spots
- Reaction calorimetry for heat release rate and accumulation profiles
- Adiabatic calorimetry and the thermal inertia factor
- Interpreting onset temperature and why it is not a material constant
Dust explosibility testing
- The 20 litre sphere and the 1 cubic metre vessel for Kst and Pmax
- Minimum explosible concentration and limiting oxygen concentration determination
- Minimum ignition energy and ignition temperature for cloud and layer
- Sample preparation, particle size and moisture, and why they decide the result
Other characterisation
- Flash point, autoignition and flammability limit determination
- Chemical compatibility and mixing calorimetry
- Self heating and bulk powder testing
Specifying and reading
- Writing a test scope that answers a design question
- Sampling so that the tested material represents the plant material
- Reading a report critically and identifying what was not tested
What you receive
- A test specification template by hazard question
- A sampling protocol for representative material
- A test report review checklist
- Assessment result and attendance record
What changes afterwards
- Testing budgets go to tests that inform a decision
- Samples represent the material as the plant actually handles it
- Reports are read for what they omit as well as what they state
- Design assumptions rest on measured properties
