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.

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
