Summary
In this project 3 parameters of a boiler are controlled. These three parameters are flow, level, and temperature. For level and flow control, we are using water as a conductor. When water will be flowing through the input water supply pipe then we ‘ll be getting an indication on computer screen to make sure that water supply is available. Similarly when water level is reduced from the set point then solenoid valve ‘ll be operated automatically to increase the water level in the boiler. For temperature control, we are using PT100 as a sensor. Its output is given to microcontroller and serial communication circuit. When the temperature increases from a set point, the microcontroller gets close the solenoid valve, which is placed at the output of the gas cylinder. The data received from the flow and temperature sensor is given to serial communication kit. This kit sends the data to the control area netwrok (CAN) transciever. CAN tranciever sends the data to the CAN controller and then to the CAN bus respectively. This data is received by the CAN tranciever, which is placed the other end of the CAN bus. That CAN tranciever sends the data to the CAN controller and to the serial communication kit. Serial communication kit sends the data to the P.C through serial port. That data is shown on the GUI, which is built using the matlab.

Water tank provides input supply of water. Input pipe of water contains flow sensor, electronic valve and one way valve. One way valve avoids water to return back. Gas cylinder is used as fuel for burner and pilot. Manual valves are used to control the pressure of the gas for both the burner and pilot, separately. Control valve concerns only with the burner, not the pilot. Steam produced in the boiler is collected at the jar, in the form of distilled water. The process of conversion of steam into the distilled water happens in way, where pipe is given a shape of coil and dipped into the cooled water tub. Cold water has a recycled system to keep cooling the water all the time. That recylcing system contains a water submersible pump, which pumps the hot the water contain in the tub, to the radiator through a pipe, that radiator cools the water with the help of a fan and sends the water back into the tub through pipes. The whole process is shown in the fig 1-1 and fig 1-2
