Powerful and controllable energy source
[attachment=17338]
ABSTRACT
Temperature dependent workplaces are the heart of industrial civilization. Powerful and controllable energy source are the most important demand of an industry. Boiler, heat exchangers provide this energy to these industries. The temperature of these sources must be controlled by means of controlling the heater coils or the flame so that it cannot damage complete system by excessive heating or else. Various temperature controlling system are hence employed to achieve this objective.
The basic concept is to sense the current status of the system and to control the source generating the heat. Various extra enhancement are like provision of a set point Valve; display status on screen etc. can be added.
INTRODUCTION
The temperature of substance or medium is a phenomenon expressing its degree of hotness or coldness and it related with reference to its power of commenting heat to surrounding. It is one of the fundamental parameters , denoting physical conditions of matters ,similar to mass ,length and time.
However temperature denotes basically an intensive property of matters .it is measure of the mean kinetic energy of molecules of substance & represents the potential of heat flow. Temperature sensing based on methods of measuring energy radiation from a hot body.
Heat exchangers , boilers, room temperature controller, warmer controller are very known type of some temperature controlling systems. These temperature controlling system are often used in industries whereas in day to day life too. The very basic step evolved in such systems is controlling the temperature of the device which causes the heating action, which in turn helps regulating the system temperature at some predefined value.
Below are some examples of temperature controlling systems discussed in brief :-
1. Warmer control system:-
This system is used to maintain a temperature of glass chamber (incubator) Where pre born babies are kept , these pre born babies are very sensitive to environment & can be infected easily by various bacteria s if kept open at room temperature . hence they are kept in such chambers for protection .the temperature of this chamber is kept at precise 37 C .
2. Medicine storing units:-
In medical fields where some medicines has to be stored at precise temperature hence are kept in such medicine storing units whose temperature is controlled by standard temperature controlling .In our temperature controlling system we are controlling the Heater s heating action maintain the temperature. A transducer is used to sense the current temperature of the system, which is further compared with the reference set temperature
