Abstract

For the design of an installation for particulate removal from flue gases containing an Electrostatic Precipitator (ESP), associated flue gas ducts and dust handling system, there are a number of factors affecting the optimal configuration. Nowadays there are required installations with ESPs for ultra-low emissions and to be able to operate with greater variation in gas flows, chemical composition, operating temperatures and dust quality.

The detailed design of the installation must consider the technological and structural aspects.

Technological aspects comprise of operating parameters as flue gas volume flow in actual conditions, flue gas and particulate analyses, changes of temperatures, pressure and other process fluctuations to determine particle properties and risks of condensing gaseous compounds into liquid or solid state and its related effects as corrosion, sticky dust and final particulate emission.

The structural design must consider a combination of a number of forces generated by wind, snow and collected dust loads, under or over pressure in the installation and must include risks for exceptional conditions of temperature, pressure and earthquakes. Design features should be included to minimise any potential detrimental effects in order to ensure operational ability and safety. Typical models for the ESP and flue gas ducts designs accurately predict performance for balanced conditions for a relatively narrow operating window, but for enlarged ranges of operation loads - in the case that the volume flow of gases at maximum load may be 3 times higher than flows frequently achieved at low loads – there are more challenging tasks.
