摘要

In the course of development bubbling FBC boilers for domestic coals, in the Laboratory for Thermal Engineering and Energy, of the Institute for Nuclear Sciences Vinca special attention was paid to the fundamental research (both experimental and modeling) of the single coal particle behavior in fluidized bed, in order to reveal influence of coal characteristics on boiler concept and design.
In order to follow coal particle behaviour and changes, and influence of bed temperature, fluidization velocity and coal characteristics, the following processes were experimentally investigated for coals of different rank:

  • bed to coal particle heat and mass transfer,
  • kinetics of devolatilization process,
  • particle fragmentation,
  • ignition temperature and start-up temperature,
  • combustion kinetics of parent coal and char
  • burning particle temperature history and bed to particle temperature difference,
  • SO2 self-retention by ash.
Experimental research was supported by mathematical modeling of the particle heating and particle temperature distribution and history, particle fragmentation and char combustion - including char particle porosity change.
In this paper most important results of this investigations are reviewed and illustrated by a number of experimental results and comparisons with mathematical models and experimental correlations.
