Heat energy is the main source of power

Carbon compounds are used as the mainsources of heat and energy.

Fuel is a combustible substance containingcarbon as main constituent, which on properburning gives large amount of heat.

Fuel which gives heat are wood, charcoal,coal, kerosene, petrol, diesel, oil gas etc.



High calorific value

Moderate ignition temperature

Less moisture content

Low non combustible matter content

Products of combustion should not beharmful

Low cost Easy to transport

Combustion should be easily controllable



Should not undergo spontaneous combustion

Storage cost in bulk should be low

Fuel should burn in air efficiency without

much smoke



They are easy to transport.

They are convenient to store without any riskof spontaneous explosion.

Their cost of production is low.

They posses moderate ignition temperature



Their ash content is high.

Their large proportion of heat is wasted.

Their combustion operation cannot becontrolled easily.

Their cost of handling is high.



They posses higher calorific value per unitmass than solid fuels.

They burn without dust, ash, clinkers, etc.

Their firing is easier and also fire can beextinguished easily by stopping liquid fuelsupply.

They are easy to transport through pipes. They can be stored indefinitely without any

loss.



They are clean in use and economic tohandle.

Loss of heat in chimney is very low due to

greater cleanliness.

They require less excess air for completecombustion.

They require less furnace space forcombustion.



The cost of liquid fuel is relatively much higheras compared to solid fuel.

Costly special storage tanks are required forstoring liquid fuels.

There is a greater risk of hazards, particularly, incase of highly inflammable and volatile liquidfuels.

They give bad odour.

For efficient burning of liquid fuels, speciallyconstructed burners and spraying apparatus arerequired.



They can be conveyed easily throughpipelines to the actual place of need, thereby

eliminating manual labour in transportation. They can be lighted at ease.

They have high heat contents and hencehelp us in having higher temperatures.



Their combustion can readily by controlledfor change in demand like oxidizing orreducing atmosphere, length flame,temperature, etc.

They are clean in use.

They do not require any special burner.

They burn without any smoke and ashes.

They are free from impurities found in solidand liquid fuels.



Very large storage tanks are needed.

They are highly inflammable, so chances of

fire hazards in their use is high.

They are more costly as compared to otherfuels.



Energy systems which usefully employ waste heat

Energy – Efficiency buildings' designed to lowerrequirements for artificial heating, cooling andlight

Products with longer lives, lower average energydemand, and greater efficiencies.

Improve energy conservation, storage and

transmission efficiency Direct use of pipeline gas instead of electricity

generated from such gas.



Production capacity of the organization

Nature of product industry is producing

Capacity of the industry to store energy

Capacity to invest with reference to energy





It is the men who do the planning,organizing, directing and controlling

The objectives for which the company is

established are attained effectively If men are managed properly, they try to

maintain a positive outlook and work for thecompany with great enthusiasm

The objectives of society can be dulyconsidered and served.



The productivity, excellence, innovativeness,profitability etc can be increased

The relationships among the employees areknown, so that they can collectively

contribute to the attainment of company’s goal

It is the men, who are solely responsible formaking use of national resources.

Helps in identifying adequate wages,incentives etc.



The psychological feature that arouses anhuman being to action towards a desiredgoal, the reason for that action.

There can be:

◦ Positive motivation

◦ Negative motivation



Interaction theory

Participation theory

Pattern concept

Achievement expectation theory



Monetary Non monetary
