Study on Combustibility of Blended-Coal for Power Station

摘要

Based on Mettler-Toledo thermogravimetric analyzer, a series of combustion experiments for two kinds of different coal samples as well as their blends were conducted. The effect of factors such as mixture ratio, heating rate on the combustion characteristics have been investigated. Kinetic parameters of combustion were then calculated by using the FWO method. The result shows that ignition temperature of coal increases with the increasing heating rate. Under the different heating rate and mixture ratio, TG curves have basically the same trend. The trends of the activation energy curves of samples are similar and show the decreased trend. The activation energy of sample A is lower than sample B, which provides fundamental experimental data for further study on the combustion process of coal.
