Abstract：Under the guidance of the"dual carbon"goals,green and low-carbon transformation has become the key path for the high-quality development of the cement industry.The industrial application of energy-saving and carbon-reduction technologies is the key to achieving industrial emission reduction.This article takes a 2 500t/d cement clinker production line as the research object,analyzes the problems existing in the kiln system of the production line,and proposes energy-saving renovation goals and renovation plans based on low-carbon cement technology,including optimizing the structure of the preheater to reduce system pressure loss,improving the ventilation in the kiln to enhance heat exchange efficiency,and applying the fourth-generation cooler and high-temperature SCR denitration system,etc.After the transformation,the standard coal consumption per ton of clinker decreased by 7kg/t.cl,the power consumption dropped by 3kW·h/t.cl,the resistance of the preheater system dropped to below 5 000Pa,and the temperature at the C1 outlet decreased by 40℃.NOX≤50mg/Nm³,ammonia escape≤5mg/Nm³,with remarkable energy-saving and consumption-reducing effects,providing a replicable technical model for the transformation of similar production lines.
