Microprocessor based Electrostatic Precipitator Controller
Electrostatic Precipitator
Controller is a single chip Micro Controller based digital
programmable Electrostatic- Precipitator’s T/R set controller. This
can be interfaced with any make of T/R set. It controls the ESP’s
filter current as per the preset value maintaining the required DC
voltage (kV) in ESP. The controller generates digital pulse for
thyristor firing in such a way that it maintains the preset spark
rate irrespective of Volume, Flow, Temperature and Chemical
properties of gas. It receives the analog feedback of kV and mA from
T/R set and convert it into digital data for processing by a 8-bit
A/D Converter. The Precipitator receives the digital signal or
on/off contact for other status like T/R oil temperature, AC current
high etc. ESPC controls the Precipitator power by changing the
ignition angle of the rectifier thyristor. SEMIPULSE operation
depends on the process type and can be used for improving
precipitation or for energy saving.
