Co-firing of coal with a solid recovered fuel as a route for reduction of sulphur dioxide emissions

Popis výsledku v původním jazyce

his work focuses on co-firing of coal with specially separated waste marked as a solid recovered fuel (SRF) for the purpose of decreasing sulphur dioxide emissions. Nowadays, it starts to be very challenging for coal fired boilers to reach tightened emission limits for SO2 which are currently set at 1 500 mg/m3 for solid fuel and power inputs from 5 to 50 MW. The main contribution of this work is that there were done long term experiments with co-firing at the real industrial boiler with real operating parameters. Three mixtures with increasing amount of SRF were proven at the grate type of boiler having power output 5.14 MW. Used mixtures obtained 10, 25 and 40% of SRF in heat input. Experimental results show that only the mixture with the highest amount of SRF decreases SO2 concentration under the current SO2 emission limits. However, this percentage of SRF in the mixture created several problems which should be sorted out. The biggest problems with this co-firing were increased concentrations of particular matter, increased concentration of NOx and higher emissions of HCl. Due to the different specific volume and mechanical properties of used fuels some potential problems with fuel preparation and fuel feeding should be taken into consideration.
