INFLUENCE OF PSD OF MAKE-UP MATERIAL ON CFB BOILER OPERATION BURNING BIOMASS
Particle size distribution of the make-up material is crucial to proper operation of any kind of CFB boilers.Particle size distribution forming circulating material in a CFB boiler mainly depends on the separation efficiency, the ability of combusted coal for thermal fragmentation and the ash content in the fuel.In this paper analysis of influence of particle size distribution (PSD) of sand particles on CFB boiler operation is reported.Experiments were carried out in the Foster Wheeler Compact CFB boiler in CHP Fortum Czestochowa, Poland.Power Plant of 120 MW and 64 MW thermal power produces 550 GWh of electricity and 450 GWh of heat consumption.Live steam parameters are (boiler) 77.1 kg/s, 515C, 11 1bar.Main fuels are hard coal/bio-70/30%, forest biomass-max 30%, agro biomass-max 20%.The results of the mass balance model for the CFB that takes into account the following physical processes (i.e.attrition, segregation, fragmentation, coagulation) and chemical processes (i.e.fuel combustion) that occur in the CFB boiler were also presented.
