Outline
According to the problems such as low production efficiency and high safety risks existing in the traditional control methods for boiler startup and shutdown in chemical production, APS (Automatic Procedure Starup/Shutdown) system control technology was studied and applied at oil burners of boiler in the whole process. The application results showed that the average temperature rise rate of the boiler was decreased from 160 ℃/h to 50 ℃/h, the startup time was decreased from 300 min to 215 min, the pressure fluctuation was dropped from 500 kPa to 200 kPa, and the input time of the oil gun was shortened from 240 min to 120 min. The fuel consumption for a single startup of the boiler was reduced from 18.81 tons to 13.43 tons and a decrease of approximately 28.6% was achieved, which improved the production efficiency and operational safety of the boiler and saved energy.
