| 摘要 |
<p>To improve the density and robustness of the products, trapped air is expelled from the piled dry coal powder in the filling chute of the extruder by injection with steam, esp. in a wt. ratio of steam: coal of 1:250 - 1:30. This range of ratios gives optimum briquette characteristics.</p> |
