Though field study on small-scale co-firing of sludge and coal in a pulverized coal boiler in a thermal power plant of Guangdong province

the effects of furnace temperature

carbon content of fly ash and boiler efficiency on boiler safety and economic benefits were investigated.The emission characteristics of NOx

SO2 and dioxin after co-firing of sludge were paid more attention.The results show that

with an increase in the sludge mixing ratio

the furnace temperature reduced

and the carbon content in fly ash and the heavy metals content in fly ash and slag increased.The boiler efficiency changed little with a small proportion of sludge

and the main pollutants emissions satisfied the national standards.The results can provide theoretical basis for collaborative disposal of sludge in thermal power plants.
