Abstract
- The combustion of a biomass with coal may be one of the most effective methods to improve energy utilisation efficiency. This study aims to investigate the combustion characteristics of distillers' grains with bituminous coal using a thermo‐gravimetric analyser. The results demonstrate that increasing the proportion of distillers' grains in coal results in a reduced ignition temperature (Ti) and burnout temperature (Tb), and activation energy (E) in the combustion stage. Therefore, the comprehensive combustion index (CCI) improves. In an O2/CO2 atmosphere, Ti increased by ∼15°C, while Tb did not change much. However, E and CCI declined relative to an O2/N2 atmosphere. Under the O2/CO2 atmosphere, with an increase in O2 concentration from 10 to 40%, Ti changed over a small range, but Tb declined from 745.8 to 641.4°C, while E and CCI improved. As the heating rate rose from 10 to 30°C/min, the values of Ti decreased (from 281.4 to 244.9°C), but the values of Tb increased significantly (from 662.8 to 745.8°C); the value of E reduced, and CCI also improved. This research could provide useful information as a practical reference for heat and power production. [ABSTRACT FROM AUTHOR]
