2080 t/h亚临界四角切圆锅炉能耗诊断研究分析

Research and Analysis on Energy Consumption Diagnosis of 2080 t/h Subcritical Four-Corner Tangential Boiler

摘要: 为了解锅炉运行情况及能耗水平，以某电厂2080 t/h亚临界四角切圆锅炉为研究对象，开展能耗诊断试验研究。试验包括煤质参数分析、灰渣参数分析、锅炉效率、空预器漏风及辅机耗电试验。结果表明机组存在排烟温度高、飞灰含碳量大、辅机耗电率高、机组漏风量大、减温水总量大且左右偏差大等问题。最后针对存在的问题提出合理化节能降耗措施。

Abstract: In order to understand the operation and energy consumption level of the boiler, a 2080 t/h subcritical four corner tangential boiler in a certain power plant was selected as the research object to conduct energy consumption diagnosis experiments. The experiment includes coal quality parameter analysis, ash residue parameter analysis, boiler efficiency, air preheater leakage, and auxiliary power consumption test. The results indicate that the unit has problems such as high exhaust temperature, high carbon content in fly ash, high power consumption of auxiliary equipment, large air leakage of the unit, large total amount of cooling water, and large left-right deviation. Finally, reasonable energy-saving and consumption-reducing measures are proposed to address the existing problems.
