摘要/Abstract

摘要： 通过现场试验和调研，从烟气温降、系统阻力、除尘效率和SO₃去除率角度，分析水媒式烟气换热装置的运行现状。结果表明，采用水媒式换热装置能够有效提高烟囱排烟温度，实现白色烟羽的消除，同时对烟尘以及SO₃具有明显的脱除效果。分析水媒式换热装置运行中存在的主要问题，并提出相应的优化及解决措施，为水媒式换热装置正常运行提供数据支撑和理论依据。

关键词: 燃煤电厂, 电除尘器, 水媒式换热装置, 白色烟羽, 优化措施

Abstract: The gas-water-gas heat exchanging system (WGGH) operation situation is analyzed through field tests and study from the aspects of gas temperature drop, system resistance, dust removing efficiency and SO₃ removing efficiency. The results show that the chimney smoke temperature can be raised through WGGH and the white smoke plume can be eliminated. Meanwhile, the removal of dust and SO₃ has obvious effect. The main problems of WGGH in operation are analyzed and the corresponding optimization and improving measures are proposed to provide important data support and theoretical basis for normal WGGH operation.

Key words: coal-fired power plant, electrostatic precipitator, WGGH equipment, white smoke plume, optimization measure
