As the Combustion and Gasification Laboratory developed, there was an increasing need to properly prepare the fuel for testing, e.g. drying, grinding or separating the dust into its various fractions. In the case of low-power stations up to 10 kW and short-term tests, typical laboratory equipment such as dryers, grinders or shakers were sufficient. However, for long-term tests, i.e. tests on a 0.5 MW stand and a 150 kW gas generator, fuel preparation in this way would be impossible.
The Fuel Preparation Laboratory was established in 2008 and comprises two locations in Warsaw. The total area of the laboratory is approximately 650 m2.
The Research Fuel Preparation Laboratory comprises three large research installations:
- the coal dust preparation installation,
- the dust fractionation installation,
- installations for the preparation of fuels from biomass and biodegradable waste in the form of dust, pellets and briquettes,
- and smaller more typical installations or the equipment itself (mills, shakers, crushers).
The first and second of the above-mentioned installations offer the possibility of safely preparing hard coal and lignite dust of an appropriate grain size (R90<2% and R200<10%) and moisture content (hard coal 1.5-5%; lignite 10-15%) for testing combustion processes in pulverised fuel burners and gas-generators. For fuel preparation volumes below 500kg, the above parameters can be significantly improved by carrying out ‘manual’ drying and screening of undesirable fractions.
The installation for the preparation of biomass and waste fuels offers the possibility to prepare dust and pellets from biodegradable fuels (vegetable waste) as well as briquettes with a diameter of 40 mm from any suitably prepared waste for energy production.
