At present, outdoor air pollution represents a great challenge as well as a great research opportunity. Particle emission from various sources from biomass combustion to burning batteries of electric vehicles have been studied:

• Combustion particles – identification and characterization of fine and submicron combustion particles entrained in the flue gas during biomass combustion. The particles are also evaluated in terms of their chemical composition, with a focus on heavy metal and organic content.

• Particle resuspension – evaluating the process of contact loss of a particle with a solid surface (resuspension) due to air movement over the surface. Activities include the identification of resuspension characteristics by evaluating long-term emission monitoring records. Computational fluid modelling (CFD) is used to model resuspension in specific urban development conditions, incorporating realistic car movements.

• Reduction of particulate emissions from energy technologies and road traffic and the effective capture of particulate matter. The activity contributes to the objective of low-emission energy production and low-emission road transport.

Further information is available on the websites of individual laboratories:

• Fine particles laboratory
  The Fine Particles Laboratory is focused on the identification and analysis of fine particles emitted by combustion processes, manufacturing processes and road transport emissions. The combination of several measurement methods covers the complete spectrum of emitted particles in terms of size and concentration. The measurements are either performed on-line or the particles are captured on filters for subsequent gravimetric or chemical analysis. The laboratory’s primary focus is on research into the formation and growth of the smallest particles during combustion processes. More information here.
  
• Aerosol research laboratory
  The department systematically and at the state-of-the-art level builds up facilities for experimental research into aerosol transport and deposition. It is equipped with up-to-date instrumentation for preparation and experimental research of liquid and solid particles. The research activities conducted currently at the laboratory include elucidation of transport of various type particles as well as assessment of their deposition during inhalation into human airways. The laboratory fundamental component is a test rig for aerosol preparation, its mixing with air and measurement of flow operating parameters. More information here.
  
• Laboratory of numerical simulations
  The laboratory focuses on research, development and testing of numerically solved mathematical models in the field of energy engineering. Within the laboratory, we focus on modelling processes combining fluid flow, thermodynamic and mechanical processes, streamlining computational times, topological optimisations, statistical modelling and artificial intelligence. We perform both evaluations and designs of new systems. The laboratory includes a number of simulation software and computer equipment. More information here.
  
• Combustion plant test room and laboratory
  The laboratory of experimental combustion is focused on the research of wood and non-wood biomass combustion, or biodegradable waste. We also deal with the development and design of hot air and hot water heat appliances. We test boilers with outputs of 10 to 200 kW. More information here.
  
• Gasification laboratory
  The gasification laboratory focuses on research and development in the field of fluidised bed gasification of biomass, alternative fuels and selected types of waste. Research activities aim at research in the gasification of various types of fuels and gasification media, research in the field of purification of produced energy gas and, last but not least, on research into the combustion of low-calorific gas. More information here.
  
• Fuel laboratory
  The fuel laboratory is focused on determining the basic fuel properties of solid and liquid fuels for the energy industry and on the research of fuel as an input raw material for the combustion and gasification process. We deal with the determination of fuel parameters using methods standardised according to ČSN, which allow us to perform measurements comparable to professional and accredited laboratories.
