集气罩

此外，增加排风量可明显提高集气罩内的流速。

Furthermore , strengthening ventilation can improve velocity in gas-collecting hood .

本文在全面研究鞍钢干熄焦及其除尘系统的工作原理和设备组成的基础上认为，除尘系统整体方案设计合理，只是集气罩的结构设计不合理造成粉尘不能被有效收集。

The whole design scheme was considered to be reasonable , but the dust can not be collected because of the irrational structure of gas-collecting hood .

气化炉内的炉表近区域温度场主要由辐射场控制，集气罩近区域温度场受对流场控制。

Temperature field near the gasification furnace surface was controlled by radiation field , and temperature field near collecting gas mantle area was controlled by convection field .

炉内温度梯度随距炉表距离的增大而减小，靠近集气罩区域，温度梯度随高度增加而增加；

With the augment of the distance to furnace surface , the temperature grads of the furnace minish , anear collecting gas mantle area , the temperature grads increase with the height .
