摘要某5 000t/d水泥熟料生产线建成投产以来，长期存在预分解系统阻力高、一级出口温度高、熟料标准煤耗偏高的问题。为降低预分解系统阻力、出口温度，节约电耗、煤耗，2019年大修期间，公司对窑系统进行了节能降耗技术改造，改造后预热器一级出口负压降低至4 500Pa，一级出口温度降低至270℃，熟料工序电耗降低至25.78kW·h/t，标煤耗降低至104.43kg/t熟料，预计每年可为公司节约成本1 360余万元。

Abstract: Since the 5 000t/d cement clinker production line of a company was built and put into operation, there have been long-term problems such as high resistance of the pre-calcining system, high preheater outlet temperature and high standard coal consumption of clinker. In order to reduce the resistance and outlet temperature of the pre calcining system, save power and coal consumption, during the overhaul in 2019, the company carried out the technical transformation of energy saving and consumption reduction for the kiln system. After the transformation, the negative pressure at the primary outlet of the preheater is reduced to 4 500Pa, the outlet temperature is reduced to 270℃, the power consumption of clinker process is reduced to 25.78kW·h/t clinker, and the standard coal consumption is reduced to 104.43kg/t clinker, which is expected to save the company by about 13.6 million yuan every year.

Key words: precalcining system outlet temperature energy conservation and consumption reduction
