BOILER FANS INTERLOCKS USING PIC MICROCONTROLLER

The objective of the project is to control and interlock the boiler fans such as Primary Air, Forced Draught & Induced Draught fans. Interlocking in thermal power station environment is necessary • To maintain the boiler pressure and • To ensure safety operation of the plant. Relay logic and wires are those which makes the system complex in finding errors. Our project aim is to transform the relay logic into digital using an to interlock the boiler fans and controlling the fans for the interrupts
