高炉煤气是钢铁企业生产中的主要能源,占企业煤气消耗的比例很大,在实际生产中由于煤气系统的不平衡导致了生产不连续、以外购能源代替高炉煤气等许多问题。介绍了高炉煤气的回收利用现状,在分析公司高炉煤气系统状况的同时,总结和梳理了高炉煤气的平衡思路,只有稳定高炉煤气供应,才能减少外购能源的消耗,降低能源消费成本。合理平衡调配煤气资源,科学制定煤气供需之间的平衡对策,对发展钢铁生产、降低能源消耗和增加企业经济效益具有重要的意义。 相似文献

在煤的层燃过程中,水本身起消极和积极的双重作用,采用适当的方法喷入适量的水,就可以发扬水对燃烧过程的积极作用而抑制其消极作用,从而实现高效节能和消烟除尘的目的。喷水使灼热的煤层产生水煤气,部分地变固相燃烧为气相燃烧,能充分利用炉膛空间,喷水能提高碳物质的消耗速度,避免析碳.实现高效低污染的清洁燃烧,喷水能使煤粒表面灰层出现裂缝或剥落,利于燃烧过程进行。 相似文献

催化助燃剂降低烧结煤耗的研究 总被引:7,自引:4,他引:3
本文讨论了烧结用催化助燃剂的研制及添加催化助燃剂降低烧结煤耗的烧结杯试验结果,试验表明:在相同的时间与反应条件下,添加催化助燃剂时,煤粉的固定碳转化率主于不中时煤粉的固定碳转化率,添加0.1%催化助燃剂强化烧结,不仅可以保证烧结矿的产质量,而且固体燃耗可降低15%以上。 相似文献

Energy-conservation based generation dispatching is the revolutionary change in operation mode which could reduce energy consumption and pollutant emissions,promote power industry restructuring,and achieve sustainable development. Social benefit evaluation of the energy-conservation based generation dispatching under the new situation and environment has come into being as an important theoretical issue. A new scenario analysis based social benefit evaluating method,which is implemented by comparing the energy consumption and pollutant emissions of different scenarios defined by the key indicators,i.e.,load factor and coal consumption structure,is proposed in the paper. Then the composition of social benefit is analyzed from the point of the dispatching mode and the coal consumption structure. The method proposed is of clear physical meaning. It is not only practical,but also applicable for the implementation of energy-conservation based generation dispatching in different phases and with different goals. 相似文献

The concepts of theoretical gas utilization ratio, smelting heat of iron ore and effective calorific value of coal were introduced in this work. The practical gas utilization ratio and the gas consumption in the shaft of a reduction unit for smelting reduction were discussed. The Corex process was optimized and the energy consumption was minimized according to the relationship of gas production in the smelting unit and the degree of iron ore reduction in the reduction unit. It was proven that the most important factor for saving energy in smelting reduction process is to use coal with suitable effective calorific value for the smelting heat of iron ore. 相似文献
