Advanced Methods of Mpgrading Electrostatic Precipitators
many electrostatic precipitators (esp) around the world have been operating for several decades. more stringent emission requirements and more challenging conditions due to fuel switching and other process changes result in a need for improved dust collecting efficiency. often, it is sufficient to improve the performance of the existing esp system by utilizing appropriate upgrading technologies. another reason to invest in esp upgrade technology is to reduce operating costs.For the existing ESP upgrade applications, some technologies may be better suited than others for reasons of layout and cost,process integration, age and design of that plant and the emission levels to be achieved. The most appropriate solution can be selected after detailed inspection and assessment of the present electrical, mechanical and gas distribution status as well as process conditions. Initially the ESP needs to be restored to mechanical and electrical operating conditions. The Upgrade solutions include full range of options for; Control System Upgrade, Extension of Field, Flue gas Conditioning. The paper will first present environmental drivers facing ESP operators. Secondly, The various ESP technological upgrades will be reviewed, including a discussion on the advantages and disadvantages of the selected upgrade methodology.
