低低温电除尘技术特点及在高灰煤超低排放工程中的应用
Characteristics of Low-Low Temperature ESP Technology and Its Application in Ultra-Low Emissions for High-Ash Coal-Fueled Power Plant
摘要
Abstract
The low-low temperature ESP achieves the goal of efficiency-enhancing and energy-saving with high SO3 removal efficiency as well.Low-temperature corrosion will not occur given the ratio of ash to sulfur more than 100.In this paper,the authors elaborated and analyzed the topics on technical parameter settings,major problems and corresponding countermeasures,pollutant emission reduction characteristics of low-low temperature ESP,etc.A typical case of 660-MW unit of Huaibei Pingshan Power Plant is presented.The test shows that the dust removal efficiency of the ESP is 99.97％,the outlet dust and PM2.5 concentrations of the ESP are respectively 4.47 mg/ m3 and 2.4 mg/m3 while the outlet dust concentrations of WFGD are 2.3 mg/m3,which proves that the combination of low-low temperature ESP with rotating electrode type ESP can not only reduce the outlet dust concentration of the ESP to 5 mg/m3,but also realize ultra-low emission for high-ash and low quality coal.关键词
