  • Evaluation of Steam

    Jan 21, 2021There, it can be seen that the coal fines start to adsorb the O 2 at a significantly lower temperature (T_ad = 133 C) than the SE biomass (T_ad = 194 C) a difference of about 60 C, perhaps due to the higher fixed carbon content of the coal and the existence of more active places where the O 2 can be adsorbed. The T_ad increases with

  • Segregation of fines

    Segregation of fines. Fines segregation can be particularly bad when liquids such as fat and enzymes are applied post-pelleting because a higher percentage will be absorbed by the fines. Also, minerals tend to bind poorly to feed and may make up a greater proportion of the fines. Feeding pellets allows animals to eat more and gain more.
