Abstract:
The combustion characteristics of textile dyeing sludge (TDS) in N 2 /O 2 , CO 2 /O 2 , and N 2 /CO 2 atmospheres, and blends of TDS with coal were analyzed using TGA (thermogravimetric analysis). Results showed that the replacement of N 2 by CO 2 resulted in negative effects on the combustion and pyrolysis of TDS. Comparing N 2 /O 2 and CO 2 /O 2 atmospheres, combustion of TDS was easier in a N 2 /O 2 atmosphere, but the residual mass after TDS pyrolysis in pure CO 2 was less than that in N 2 by approximately 4.51%. When the proportion of TDS was 30–50% in the blends of coal with TDS, a synergistic interaction clearly occurred, and it significantly promoted combustion. In considering different combustion parameters, the optimal proportion of TDS may be between 20–30%. The activation energy E a value decreased from 155.6 kJ/mol to 53.35 kJ/mol with an increasing TDS proportion from 0% to 50%, and it rapidly decreased when the TDS proportion was below 20%.
