Key words:Air leakage control system

air preheater

The system is applicable to radial sealing clearance adjustment at hot end of air preheater in 200MW1100MW generator set and can be used to automatically control the air leakage of either three-segment or two-segment air preheater with bendable sector plate or adjustable rigid sector plate. Two modes, i.e. position control and load control, being a standby mode for each other; the control mode can be chosen flexibly; in load control mode, load signal, main/standby motor current signal and temperature signal have good stability, not affected by the field environment; over current regulation and protection function is provided, ensuring the reliability of automatic operation in any running conditions; this system has a high automation rate.
