Thermogravimetric Analysis on the Combustion Characteristics of the Blend of Organic Waste Liquid and Coal

Article Preview

Abstract:

The characteristics of ignition and combustion and activation energy of YiMin coal and organic waste liquid and their blends in different blending ratio are studied by thermogravimetric analysis. The experimental results show that ignition and burning characteristics of coal are better than organic waste liquid. The ignition temperature of organic waste liquid will decrease, while the maximum weight loss rate will increase and the time corresponded to maximum weight loss rate will get earlier with the increase amount of the coal added. Activation energy of samples is calculated. Compared with the coal, the activation energy of the low temperature zone of organic waste liquid is lower and its ignition characteristic is better. The activation energy of the high temperature zone is bigger and its combustion characteristic is worse. The coal added will reduce the ignition characteristic but promote the combustion characteristic of organic waste liquid. The analysis of the combustion index S indicates that the comprehensive combustion characteristic of the organic waste improves significantly when coal is blended, and the best blending ratio is 2:3.
