Dust Explosions in the Process Industries

Postgraduate course

Course description

Objectives and Content

Objectives The course provides an overview of the state-of-the-art in research on dust explosions. The lectures emphasise physical phenomena and principles for risk-reducing measures.

Content

The course describes ignition and combustion properties of powders and dusts, methods for prevention and control of dust explosions, lessons learnt from accidental dust explosions as well as methods for testing the ignition, combustion and explosion properties of dust layers and dust clouds.

Learning Outcomes

On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student is able to:

  • describe the formation of flammable dust clouds
  • discuss physical phenomena related to the particle-laden flow in dust clouds
  • describe ignition and combustion phenomena in dust layers
  • describe ignition and combustion phenomena in dust clouds
  • discuss the mechanisms for flame propagation for various types of dust
  • categorise methods for prevention and mitigation of dust explosions
  • discuss the chain of events and lessons learnt form relevant dust explosions accidents
  • explain the principles for risk analysis, risk assessment and risk management for industrial facilities where dust explosions represent a hazard

Skills

The student is able to:

  • explain the methods for testing ignition, combustion and explosion properties of dust samples
  • discuss relevant means of explosion protection for a given industrial facility
  • give examples of past accidents for various industries
  • conduct a literature survey on selected aspects of dust explosions
  • give an oral presentation of the literature survey

General competence

The student is able to:

  • identify relevant dust explosions hazards for a given system
  • propose suitable risk-reducing measures for a given system
  • combine various principles for explosion protection for a given system
