[email protected]Stable operation of the electrostatic precipitator, the pre-cipitation rate can be improved by greatly increasing the external voltage.As a result, the external voltage can be controlled at around 18kv so as to achieve a good pre-cipitation effect in the experiment.2.
Study on charging and electrostatic precipitator operation during unit start-up and shut-down was carried out to verify de-dusting performance.It requires the manual control of the secondary voltages to be lower than sparking voltage of 10~15kv in case of oil and/or co-fuel firing condition of boiler.
