INTRODUCTION

In Industry & mills, the fuel which is feeded to the

furnace is controlled manually. So there is loss of

fuel energy and the extra fuel generated is

wasted. It may be controlled by controlling the

feeder or belt.

The solution to this problem is AUTOMATIC

TEMPRATURE CONTROL OF FUNACE. It is

very useful to managing and controlling of the

temperature of furnace.

AIM OF THE PROJECT


5/16

The main aim of this project is save the fuel which

is feeded to the furnace. This is main done by the

controlling the temperature of furnace. By

analyzing the temperature, our system controls

the feeding system.

Here we use a temperature sensor which

can sense the temperature of the furnace ,on

sensing temperature it will forward the measured

temperature to the microcontroller which controlthe entire operation of controlling temperature.

WORK ING OF THE PROJECT


8/16

Here we have used a temperature sensor which will sense the

temperature of the boiler, on sensing temperature it will forward

the measured temperature to the microcontroller which control theentire operation of controlling temperature.

Controller used here is a PIC controller which has

inbuilt ADC using the ADC function the received signal is

processed.The microcontroller compares the sensed temperature with

the reference temperature which is either maximum or minimum

temperature of the furnace and thus controls it.

If the temperature of furnace increases the maximum limit,the furnace is automatically OFF by relay. If the temperature is

less then the minimum limit then the furnace is automatically ON.

Thus the fuel has been saved.

MICROCONTROLLER

PIC16F72)The basic criteria for choosing a microcontroller suitable for theapplication are:1) The first and foremost criterion is that it must meet the task at hand

efficiently and cost effectively. In analyzing the needs of a

microcontroller-based project, it is seen whether an 8- bit, 16-bit or

32-bit microcontroller can best handle the computing needs of the

task most effectively. Among the other considerations in this

category are:

2) The second criterion in choosing a microcontroller is how easy it isto develop products around it. Key considerations include the

availability of an assembler, debugger, compiler, technical support.3) The third criterion in choosing a microcontroller is its ready

availability in needed quantities both now and in the future.

CONCLUSION

We Have Successfully Completed The Project Of furnaceController . Through this Project We Conclude That The

Temperature Of The furnace Can Control AutomaticallyUsing Temperature Sensor And Microcontroller.

Microcontroller Successfully Control The Feeding OfFuel For furnace And Thus Save Fuel As Well As Control Its

Temperature
