In the present era of neck- to-neck competition, the cost of production plays a vital role. As the price of liquid fuels, especially furnace oil are growing at steeper rate than solid fuel price, substitution of furnace oil to solid briquette is one of the alternative available. In the war of globalization only fittest can survive. Furnace oil used in Boiler or Thermic oil heater can be totally substituted by Briquette with an equivalent ratio of 3:1 Kg/Litre on the basis of calorific value. This usually results in saving of more that 40% in operating cost & will have attractive payback period.
