摘要

Compared with optimizing electrical filter (EF) designs and increasing field numbers, optimizing the modes of the electric power supply of corona electrodes is more economical for increasing the level of degree of dust cleaning. Moreover, the simplest and least expensive way is to change the form of the supply voltage other than unipolar by applying, in addition to any kind of standard power supply, for example, a pulse from the console of a high-voltage pulse power source (PPS) in a microsecond duration based on high-voltage power thiratrons. Numerous experiments have been performed on an EF-type EGA-35-9-5-3 with a unipolar voltage of approximately -40 kV, which is supplied by a standard unipolar power source (i.e., ATF 600). The optimal pulse duration is determined to be 20 – 60 μsec (with a duty ratio of approximately 200%), and the repetition period is approximately 4 msec (250 Hz). A study aiming for almost a ten-fold increase in the service life of PSS auxiliary devices was reduced to the development of a new electron-beam switch ELV 50/100M instead of a high-voltage power thyratron TGI1-2500/35. The parameters of the electrical circuit were optimized via computer simulation. Results showed that replacing a power thyratron switch with an electron beam does not affect the output pulse parameters of auxiliary devices. In accordance with the minimum value of chimney dust emissions and a predetermined algorithm, the electric operating modes of PSS auxiliary devices were optimized for each of the boiler’s mode of operation by using an intelligent control system. The initial data on dust emissions for the control system were determined by using an optical dust meter. The electrical circuit of an intelligent control system for the automatic optimization of the PSS auxiliary device’s mode of operation is under development. Its implementation requires further verification in the field.
