Accurate flow measurement and projection allows engineers to design adequately sized facilities for the transportation (sewers and pumps), storage (basins, ponds, and tanks), and treatment (physical, biological and chemical) of wastwater. Controlling the flows to and from wastewater treatment facilities ensures that various processes work properly.
There could be an elaborate answer ! In short - for an efficient, reliable, and safe boiler operation, there is a need of basic instrumentation. 1. Safe sequence of motors and control devices. 2. Air fuel ratio control. Fuel measurement meter. 3. Inlet water flow measurement and control to maintain safe water level. Mobrey switch or suitable level switch or transmitter. Water flow meter. 4. Differential steam pressure control - pressure switch or pressure transmitter. 5. Firing sequence controller.Purging sequence. Flame detection and ignition control. 6. Two element or three element water level control method. 7. Safety valves. 8. Fuel tank level control if not gas used. 9. Dearator level control, deareator pressure / temp control 10. Alarm and trip limits and control 11. Suitable control cabinet with PLC or hardwired logic and devices and suitable user interface / HMI 12. Exhaust temp, and other sox, nox measurement. 13. Blow down method and control. 14. Intet water quality monitoring and control. If coal or bio mass used there will more add on instrumentation and control necessary.
Quickly. Power. Remote control.
software,control,mechanics,electronics,thermodynamics are the most important
Actuators are used for the automation of industrial valves and can be found in all kinds of technical process plants: they are used in wastewater treatment plants, power plants and even refineries. This is where they play a major part in automating process control. The valves to be automated vary both in design and dimension. The diameters of the valves range from a few inches to a few metres.
