炼钢电弧炉是使用电能来熔化炉料,炉内除电能外,还有电极氧化热、炉料氧化热和熔渣生成热等热能。另外,为了加快熔化速度,实现节能,最近世界上许多国家正采用了油氧混吹等辅助加热节电措施。另一方面,在能量损失方面,除回路损失外,冷却水、烟尘排放、炉体散热等等都要损失大量的热能。因此炼钢电弧炉能量收支涉及的范围是多方面的,要详细探讨炉子的效率就得把上述所有因素等等全都考虑在内(关于这一点请参阅JIS 相似文献

In this paper, the variation of electric energy consumption in the AC electric arc furnace (EAF) with various production parameters is studied using a developed computer program. The energy equation is modelled using the first law of thermodynamics. The effects of temperature of liquid steel, stack gas, scrap pre‐heated and cooling water and duration at which the EAF cover is open on electric energy consumption are investigated. The calculated electric energy values are compared with the actual electric energy used in the EAF and values received from literature. They are in a good agreement.

与西方发达国家相比,我国家电能耗浪费是惊人的。西方发达国家早在上个世纪70年代就开始在家电降耗方面作出了卓有成效的努力。在我国,一场家电节能之战正在打响,冰箱和洗衣机的降耗尤其令商家重视。待机节能也是家电降耗的一个重要环节。 相似文献

Electric energy is one of the primary energy sources consumpted in cotton textile processing. Current energy cost rate is reported about 8–10% in the total production cost of an ordinary textile product manufactured in Turkey. Significantly important share of this energy cost is electric energy. The aim of this paper was to investigate unit electric energy consumption of cotton textile processing stages using real-time measurements method. Actual and estimated Specific Energy Consumption (SEC) values for electric energy was calculated in the cotton textile processing stages of spinning, warping–sizing, weaving, wet processing and clothing manufacturing. Actual electric energy consumption data are gathered from monthly records of the involved plant managements. Estimated electric energy consumption data is gathered through on-site measurement. Actual and estimated electric energy consumption data and monthly production quantities of the corresponding months are used to facilitate specific electric energy consumption of the plants. It is found that actual electric energy consumption amount per unit textile product is higher than the estimated electric energy consumption amount per unit textile product of each involved textile processing stages. 相似文献
