A RETROFITTABLE COMBINED SUPPORTING SYSTEM FOR SINGLE FIELD MULTIPLE UNIT ELECTROSTATIC PRECIPITATOR IN A THERMAL POWER PLANT WITH REDUCED HEIGHT TO WIDTH RATIO OF THE ELECTROSTATIC PRECIPITATOR

摘要

The invention relates to a retrofittable combined supporting system for single field multiple unit electrostatic precipitator in a thermal power plant with reduced height to width ratio of the Electrostatic precipitator, comprising : a beam (2) which supports the Electrostatic precipitator bearings and columns (3,4) supported on foundations; a plurality of common columns (4) replacing adjacent columns of individual Electrostatic precipitators; an open web lattice beam (2) made of rolled steel angles; at least one knee bracing (5) connecting the open web lattice beam (2) and the columns (3,4); wherein the columns (3,4) are made up of built up rolled beam sections, and wherein the common columns (claim (2)) are placed in the center of the open space in between the units.
