Abstract
A system for controlling an electrostatic precipitator includes a computer control system with a computer and a controller in operative communication with an electrostatic precipitator. The computer control system is operative to control performance of the electrostatic precipitator by controlling one or more of: a) a power supply that controls voltage between an electrically grounded vertical plate and a metallic wire electrode in the electrostatic precipitator; b) a first feeder valve and a second feeder valve in a hopper; and c) a power supply to an electrical coil in operative communication with a rapper.
Claims17
A system for controlling at least one electrostatic precipitator comprising:
- a computer control system that comprises a computer and a controller in operative communication with the at least one electrostatic precipitator;
- and
- the computer control system operative to control performance of the at least one electrostatic precipitator by controlling one or more of:
- a power supply that controls voltage between an electrically grounded vertical plate and a metallic wire electrode in the at least one electrostatic precipitator;
- a first feeder valve and a second feeder valve in a hopper;
- and
- a power supply to an electrical coil in operative communication with a rapper,
- wherein the computer correlates an ash temperature measurement in the hopper and a voltage provided by the power supply to determine a sparking condition.
A method for controlling an electrostatic precipitator comprising:
- transmitting a signal from an electrostatic precipitator, a measuring device for determining flue gas particulate matter content, a rapper system having an electrical coil powered by a power supply, and a hopper associated with the electrostatic precipitator, to a computer control system, where the computer control system comprises a computer and a controller;
- and
- transmitting a signal from the computer to the controller for controller adjustment to the electrostatic precipitator based on historical data capture or based on correlations between transmitted signals, wherein the computer correlates an ash temperature measurement in the hopper and a voltage provided by the power supply to determine a sparking condition.
