摘要: Spent mushroom compost and coal tailings are wastes that could be used as energy sources, through combustion in a fluidized-bed. Our previous pelletization studies produced denser, yet friable fuel, which dust on transport, handling, feeding. Thus, suitable binder for these materials was required to enhance pellet properties. Inorganic (caustic soda) organic (starch) binders were selected range of tests. Pelletization at elevated temperatures also assessed evaluate the softening any lignin present straw component compost. Small amounts (up 1 wt %) both increased tensile strength, where starch had more pronounced impacts, doubling strength 411 kPa. (45−75 °C), however, improved overall quality significantly, increasing over 600 kPa, although additional temperature increases 125 °C) did not result further improvements. Whether ...
