Substituting other Fuels with LPG

Comparison between and LPG as fuel

COMPARISON BETWEEN ELECTRICITY AND LPG AS FUEL


ENERGY REALISED FROM ONE UNIT OF ELECTRICITY

 

SNO

DESCRIPTION

VALUE

1

One unit of electricity

1 KWH

2

Energy realised per KWH

860 Kcals

3

Overall efficiency

100%

4

Hence, energy realised per KWH

860 Kcal


QUANTITY OF LPG REQUIRED TO REALISE 860 KCAL OF ENERGY

 

SNO

DESCRIPTION

VALUE

1

Net Calorific value of LPG per KG

10950 Kcal

2

Handling losses etc = Nil, hence energy per KG

10950 Kcal

3

Overall combustion efficiency

92%

4

Hence, energy realised per KG

10950 x 0.92 = 10074 Kcal

5

Qty of LPG to realise 860 Kcal of energy

860 / 10074 = 0.0854

 

THEREFORE, 1 UNIT OF ELECTRICITY = 0.0854 KGS OF LPG

Please note that the values mentioned above are for indicative purpose only. The actual values would be dependent on various parameters such as burner efficiency, furnace specifications, LPG specifications etc.
