Compared with pure coal and bagasse/coal blend, T i and T p of their blends were lower than those of coal; R p and R v of their blends were higher. However, M r of their blends was higher. From the perspective of efficiency, the cocombustion of bagasse and coal has complementary advantages based on low T i, T p, and high R p, R v.
