Streszczenie
The paper presents the results of experimental studies constituting a comparative analysis of the combustion of
coal slurry, brown coal, hard coal and biomass in the form of pellets. The study was conducted using a test stand with
a circulating fluidized bed (CFB) with a capacity of 12 kW. The analysis included, among other parameters, the total
combustion time, the maximum temperature on the surface of the fuel, the ignition time, the time of volatiles combustion and
the time of the burning of char. The general conclusion based on experimental studies is that coal slurry pellets, due to its
characteristics and behaviour during the combustion process in a circulating fluidized bed, can be a valuable energy source.
