Investigation on catalyzed combustion of wheat straw by ...

Jan 10, 2011  The combustion profiles of different blends with different catalysts and the pure wheat straw had been compared. Fig. 1 shows the TG–DTA profiles of wheat straw, and the curves reveal that combustion of wheat straw has been mainly divided into two stages. In the temperature range 100 °C–500 °C, there were two exothermal peaks in the DTA curve.

From all samples, M3P1, M1P2 and M2P3 do not meet the specifications, since they have densities below 600 kg/m 3. The results show that when the moisture content increases, the bulk density of the pellets decreases.
