摘要
完成超低排放改造后，脱硫系统运行能耗大幅增加，脱硫厂用电率平均值为1.40%，折合供电煤耗约为4.4 g/（kW·h）。随着火电企业经营压力加重，超低排放运行时必须同时兼顾节能和减排双重目标。基于此，选取了33台不同工艺（单塔、双塔）的600 MW级机组作为研究对象，从脱硫厂用电率和单位脱硫能耗2方面分析了运行能耗情况，并重点分析了能耗影响因素。最后，从开展能效对标管理、脱硫系统运行优化、关键设备节能改造、浆液品质把控、精细化检修、合理使用脱硫添加剂等角度，对脱硫运行节能进行了展望。
Abstract
Operation energy consumption of flue gas desulfurization (FGD) increases greatly after finishing ultra-low emission retrofit
the average power consumption rate is 1.40%
which is equivalent to power supply coal consumption of about 4.4 g/(kW·h). With the increase of thermal power plants' operation pressure
ultra-low emission operation should consider both energy saving and pollution reducing. Taking 33 600 MW-level units using single-tower or double-tower FGD process as the research object
operation energy consumption was analyzed considering both power consumption rate and power consumption per unit of FGD. Meanwhile
the influencing factors of operation energy consumption were emphatically analyzed. Finally
outlook on operation energy saving work of FGD was proposed
considering measures including energy efficiency benchmarking management
operational optimization of FGD
energy-saving retrofit of key devices
quality control of slurry
detailed maintenance work and rational use of desulfurization additives.
