The polyfuel is a mixture of diesel, petrol and kerosene, with very high calorific value. It can be used in boilers, furnaces, stoves, in agricultural firms, etc.

Fuel oil, also called furnace oil, fuel consisting mainly of residues from crude-oil distillation. It is used primarily for steam boilers in power plants, aboard ships, and in industrial plants. Commercial fuel oils usually are blended with other petroleum fractions to produce the desired viscosity and flash point.

Typically it has a calorific value as 10000 cal/gm. The furnaces which are used mainly for heating or pre-heating a large quantity of metal, are the main users of FO. This can be stored in vertical as well as horizontal tanks, above ground or even underground in some cases. The dimensions and capacities of these tanks are predefined in India by CCOE, which is the regulating body for fuel storages.

For direct burning, FO is viscous as well as not suitable for complete combustion. It is pre-heated to 55 degrees Celsius onwards, depending upon application. The flow increases with temperature and it improves the combustion also. A water based scrubber is used in the exhaust chimney of furnace, which arrests considerable amount of carbon suite and improves the emissions.

The entire FO yard, as per IS standards, pre-heating in storage tanks as well as pipes& Pumps etc, pumping station, level controls, control-panels and entire distribution pipeline is designed taking into consideration the application, required capacity of storage, logistics, available space and government norms.
