冶金矿产：LSM钢厂设计了一套混合系统，即从储料仓取出焦炭按需要的比例与聚合物混合并分配给碳喷射器。在LSM钢厂，以橡胶作为碳源（混合焦炭）用于电炉炼钢也已成为标准操作。电能消耗从398.5kWh/t降低到387kWh/t。当FeO含量从27.7%降至27.2%时，钢中碳含量也减少了。同样，在SSM钢厂加入橡胶和焦炭混合炼钢，降低了氧气消耗。在OneSteel钢厂进行的电炉加入废弃橡胶、塑料的炼钢试验取得了以下成效：改善了炉渣发泡性，提高了电弧炉的用能效率，缩短了通电时间和出钢-出钢时间，同时降低了碳耗。

英标型钢：
ρρg--设计工况下，供回水温度所对应的水的密度，kg/m3。故有ΔP1≤3-gH（ρh-ρg）/1kPa当仅在供暖引入口设压差控制阀时，其控制压差必须小于等于3-gH（ρh-ρg）/1kPa，才能保证系统运行过程中，温控阀上的作用压差能够小于其正常工作的压差。另外，由于设计工况下进行水力计算时，不考虑自然作用压头，故根据式有：P1=P3+Ps由此可见，只有当设计工况下不利环路的阻力损失（P3+Ps）小于3-gH（ρh-ρg）/1kPa时，才可以采用方案1。
