Best practices implemented. Technical issues. Future plans.
In gland seal valve set point was given through pneumatic PID controller for its operation. Its failure will result in tripping of TG. Now a bypass arrangement is made in which input signal is given through I/P converter and whose output is given to gland seal control valve. Set point is given through PID which is programmed in DCS Benefits:- Tripping can be avoided. Maintenance & spare cost of Controller is reduced
Fuji make CO analyzer is installed in Boiler-2. In CO analyzer the value is oscillating form negative to positive and at last it is showing max value The Analyzer also showing Error no-3 which means circuit is faulty. Action taken :- Detector voltage set as per given voltage. Counter set Sensor signal voltage set to1.8V.
