Control Strategy Study on Drum Water Level of Supercharged Boiler Based on Radiation Energy Signal

Abstract:

Article Preview

The deficiencies of drum water level control system and unstable combustion of supercharged boiler could result some serious accident such as water level fluctuating greatly, pipes in furnace overheating and bursting, boiler loss water. In order to solve the problems, flame detect system was used to get flame images of boiler's furnace, and radiation energy signal was introduced into drum water level control system to add one auxiliary control loop of combustion side. The new control strategy was established and simulation model was set up. The simulation results show that the new control system could adjust feed water within 20s, and eliminated the disturbance of water level within 60s by way of monitoring radiation energy signal, the fluctuating range was also decreased significantly.
