PLC AUTOMATION & CONTROL SYSTEM FOR STEAM POWER PLANTS

A boiler installed for simple process steam requirements does not need much automation since small variationin steam pressure and temperature are negligible. However, when a boiler is installed for steam turbine, mucmore accuracy is required. Further, solid fuel used in boiler is much more complicated than liquid or gas fuelsHence, complete automation system is installed for fuel handling, pressure regulation, flow of steam and stea

turbine electrifications.

First of all, total automation layout for inputs and outputs of PLC is finalized in accordance with boiler designand size :

Fuel feeding to the furnace is automated through VFD installation and attached with boiler pressure &temperature. Pressure drop of steam increases fuel feeding and vice versa:

Thermocouples

Pressure Swithes

Parameteres Display

Boiler Feed Water Pumps are connected with boiler water level controllers through PLC to maximize boilerwater tubes safety. FD fans, ID fans, dumpers and ash rotary motors are also controlled by centeral PLC. Al

these parameters are displayed in individual controllers along with central HMI for continuous monitoring:
