It is difficult to achieve the analytical solution of temperature field with internal Joule heat generation under steady state electric field, especially when the distribution of the Joule heat is complicated.
此方法使焦耳内热源温度场问题得到简化 ,并且不论焦耳热源的分布如何 ,不论何种正交坐标系均可采用。
Coal characteristics analyses denote that Kailuan metallurgical coal concentrates being mainly of fat coal, coking coal and 1/3 coking coal with strong caking power, good coking ability and medium ash and sulfur content.
开滦矿区的炼焦精煤主要有粘结性强、结焦性好的肥煤、焦煤及 1 3焦煤 ,灰、硫含量为中等水平 ;代替鞍钢单种煤的炼焦试验取得了较好的效果 ,焦炭强度、粘结指标均可提高 ;开滦炼焦精煤可取代鞍钢现用的肥煤、焦煤和 1 3焦煤用于炼焦 ,并可提高焦炭强度。
