A boiler is a closed vessel that transfers heat from fuel combustion to water, converting it into steam for power generation, industrial processes, and heating. Boilers are classified based on their heat source, circulation method, orientation, and whether they are stationary or mobile. A boiler is a mechatronics system that uses sensors to monitor heat, water level, and pressure, sending signals to a control unit consisting of a microcontroller and other components that regulate the system without human interference through actuators like water valves.

2. BOILER

3. DEFINATION A Boiler is a closed vessel in which heat produced by the combination of fuel is transferred to water for its conversion into steam at desired temperature and pressure.

4. Use. The steam produced by the boiler my be supplied to steam engines or turbines for power generation,indusrial process work,heating installations and hot water supply etc.

5. CLASSIFICATIONS OF BOILERS

6. FULTON SOURCE OF HEAT. ELECTRIC STEAM BOILER WATER TUBE AND FIRE TUBE. NATURAL CIRCULATIONS AND FORCED CIRCULATION. HORIZONTAL,VERTICAL OR INCLINED. SINGLE TUBE OR MULTI-TUBE. STATIONARY OR MOBILE. EXTERNALLY FIRED AND INTERNALLY FIRED.

7. Boiler as a mechatronics system Boiler is mechatronics system as it mechatronically controls Heat level water level Pressure level

8. Mechatronics System A system is said to be mechatronics system if it ; Contain built in inteligence. Control system. Can perform required action without human interference.

9. ELEMENTS OF MECHTRONICS SYSTEM SENSOR SIGNAL CONDITIONER A/D CONVERTER MICRO CONTROLER D/A CONVERTER CORRECTION UNIT

11. SENSORS IN BOILER Heat sensors Water level sensors Pressure sensors Wetness sensors

12. Heat sensor A heat sensor sense the heat and send error signal to the microcontroller which take the desired action

13. Water level sensor Water level sensor is a sensor which continously measures the amount of water in a boiler

14. Pressure sensors Pressure sensors are measures the pressure in steam line and in boiler

15. Control unit Signal conditioner a/d converter Micro controllers d/a converter

16. Signal conditioner Signal conditioner manipulates the error signal from the sensor in the condition which is suitable for micro controller usually In boiler control system a signal conditioner is differential amplifier

17. A/D & D/A CONVERTERS They perform analog to digital & digital to analog conversions In order to make the error signal suitable for micro processors and correction element

18. Micro controllers It decides what action is to be taken in order to achieve the desired conditions.

19. Correction unit It produces a change in the process to correct or change the controlled conditions. The actuators is an other name of correction unit it provides the power to control action.

22. FULTON ELECTRIC STEAM BOILER.

23. WORKING

24. STARTING OF BOILER. Open the steam valve. Open all the valves in the water feed line. Open water gauge valves.

25. STARTING OF BOILER. Switch on both main power switches. Switch on the boiler control circuit using the switch on the top of control pannel box.

26. INSTRUCTIONS

27. Carry out the following operations Each morning start the boiler and generate not more than 5 p.s.i.g. steam, then switch off the boiler. Open the boiler blow off valve for approximately 5 seconds then closed the valve. Open the water guage blow off valve for 5 seconds.

28. MAINTENENCE Weekly. Three Monthly Semi Annually

29. Water tube and fire tube There are two ways in which water can be heated for being converted into steam.
