Study on driving circuit of automatic control system for boiler damper

The working principle of traditional automatic control system for boiler damper in minitype power station is introduced and the features of faults frequently occurred in its different units and their influences on production are analyzed. A driving circuitry of boiler damper automatic control system suitable for field application is designed and tested,which is successfully applied to real control system. The practice shows that the circuitry is of stable and reliable performance.
