焦炉地面除尘站系统的改进 总被引:1,自引:1,他引:0
苏钢集团公司炼焦厂于2005年改建投产了1座50孔JNK43-98D型焦炉,在改造炉型的同时,我们借鉴国内外同行业焦炉除尘的经验,自行设计了1套集焦炉出焦除尘和装煤除尘于一体的地面除尘站系统,该系统投入运行后,焦炉烟尘和废气排放达到了国家规定的排放标准,本文重点介绍地面除尘站系统自行设计的改进情况. 相似文献

以某焦化厂焦炉集气管系为研究对象,在分析焦炉集气管系特性的基础上,运用机理建模方法建立焦炉集气管系的数学模型,针对焦炉集气管系耦合严重的特点,设计了一种基于模糊控制原理的智能解耦方案。对解耦方案进行仿真实验分析,结果表明:该解耦方案基本能够消除焦炉集气管间的耦合作用,为焦炉集气管系解耦控制的深入研究提供参考。 相似文献

Assessment of the coking behaviour of coals and blends by conducting coking tests in experimental coke ovens still continues to be the most reliable method and is extensively used all over the world. The oil-cum-gas fired experimental coke oven developed at CFRI has a coal charging capacity of 1100 kg and simulates industrial carbonising conditions. The oven is capable of intermittent operation and can be brought up to working temperature within 36 hours.Correlation studies of coke quality were carried out by conducting a series of coking tests on the same blend, carbonised under similar conditions in the CFRI experimental coke oven and the commercial coke ovens of Bokaro Steel Plant. The study has revealed that the physical strength of the CFRI oven coke compares favourably with the Bokaro oven coke. M40 and M10 indices of the commercial oven coke can be predicted fairly accurately from the results of CFRI oven coke.T-tests performed on the shatter results showed that at 5% probability level there was no significant variation between the shatter indices of both cokes. The quality of the gas produced from the CFRI test oven was very similar to that of the gas produced from the Bokaro ovens. 相似文献

Several pitch materials and a petroleum coke were added to coke oven charges in an attempt to make good metallurgical coke from Canadian coal of poor coking quality. Coal and petroleum pitches were added to a low fluid western Canadian coal of medium volatile bituminous rank, and the blends coked in a technical-scale moveable wall test oven having a 230-kg charge capacity. Pitches improved coke tumble test indices, the principal coke quality parameter related to blast furnace performance. Varying levels of petroleum coke were added to an eastern Canadian coal of high volatile bituminous rank, and the blends, some partially briquetted, were carbonized in a test oven. Tumble indices of coke from the partially briquetted charges approached an acceptable level. These investigations confirm that petroleum products as well as coal derivative can play a useful part in the production of a metallurgical strength coke from poor or non-coking coals. 相似文献

分别从配煤成本、生产设备、环保和工艺等方面评价了改为捣固炼焦后的运行情况,改造后配煤成本降低50~180元/t焦,生产故障时间和设备故障时间导致的晚点分别增加10.7倍和3.3倍,同时K2、K均、K安都有不同程度的降低,在保证不损害炉墙的前提下,焦炭的反应后强度指标会比原设计为捣固的稍差. 相似文献
