摘要： An apparatus and method for controlling voltage applied to an electrostatic precipitator is disclosed. This apparatus includes a pulsating, direct current, voltage mechanism that is operable to receive power from a single phase, alternating current voltage source, and a spiral wound filter capacitor, wherein the pulsating, direct current, voltage mechanism is electrically connected in parallel to the spiral wound filter capacitor and the spiral wound filter capacitor is electrically connected in parallel to the electrostatic precipitator. Optionally, a resistor is present to lower the transient voltage rating of the spiral wound filter capacitor. A switching mechanism may be utilized to apply differing amounts of capacitance and inductance in order to apply a range of voltage waveforms to the electrostatic precipitator to potentially maximize particulate collection efficiency for the electrostatic precipitator.

摘要： A system and method for verification of acoustic horn performance is disclosed. This system and method includes a pressure detecting mechanism that converts at least one vibratory sound energy pulse, which is followed by at least one vacuum pulse or at least one negative pressure pulse, into a signal that is proportional to a level of sound energy, and the pressure detecting mechanism is operable to be connected to an acoustic horn. There is a measurement device that measures a value that correlates to the signal that is proportional to a level of sound energy and is electrically connected to the pressure detecting mechanism.

摘要： An improved method and system is provided to control the rapping process used to clean the internal collection plates and discharge electrodes of electrostatic precipitators. The system obtains the performance characteristics of a first rapper and calculates a rapper lift value. The system then obtains performance characteristic data from two or more additional rappers and calculates rapper lift values for each of the rappers. Finally, the system compares the rapper lift value of each additional rapper and adjusts its performance characteristics so that it substantially approximates the performance characteristics of the first rapper.

摘要： Form factor measurement and fault detection equipment to determine proper sizing of electrical components and efficiency of an electrostatic precipitator (22) by calculating a system form factor from either primary voltage or current. A power source (10) connects serially to an inverse parallel SCR1 and SCR2, to a current limiting reactor (16), and to a T/R set comprising a transformer (18) and rectifier (20) which supply power to precipitator (22). A current transformer (26) senses input current between the reactor (16) and T/R set (18,20) to signal an input scaling and signal conditioner (28) connected to a current meter (34), a voltage meter (39) and a computer (40) having a display monitor (42). The computer (40) is also connected to an SCR control circuit (24) of SCR1 and SCR2. The appropriate electrical characteristic is converted to both its RMS value and average value and then sent to the computer (40). The computer (40) divides the RMS value by the average value and sends the resulting form factor value to the display (42). If system form factor value is not sufficiently close to the purely resistive circuit value of 1.11, then equipment resizing is needed to increase system efficiency. Additionally, secondly electrical characteristics are used to calculate fractional conduction. If the fractional conduction is not sufficiently close to a desired level, equipment adjustments are made to increase system efficiency.
