Abstract: |
The material particle diameter, bed height, steam flow is the main factors in affecting steam for the semi-coke waste heat recycled. In order to study the effect of these factors on the recovery of residual heat and steam energy increased, a gas-solid heat transfer experimental system was established. The three factors were optimized to improve the waste heat recovery of the semi-coke, and the optimal combination of these factors was approved by orthogonal experimental method. The results showed that reduce the average particle size, improve the steam flow rate, increased the thickness of the material layer is beneficial to the increase of waste heat recycled. The optimum combination of factors is 7.5kg·h-1 of steam flow, the average particle size of particles is 0.009m, and the thickness of the material layer is 0.6m. The influence degree of the waste heat recovery is particle size, steam flow and layer thickness in turn. |
