Technology for Making Briquettes from Coal and Coke

Installation of the coal/coke briquetting plant of capacity 10 TPD costs about Rs.30 lakh. The production of briquetted fuel depends on availability of coal or coke fine rejects and demand of briquetted fuel, price of briquettes and demand of the technology keep on changing. An estimate shows the payback period for the said plant is about five years.

With the increase in demand for coke, CSIR-CIMFR developed partial substitutes of coke by making briquetted fuel. The industrial briquettes having properties equivalent to prime hard coke could be made possible by utilization of coke breeze and coal dust. The processes developed in lab scale was tested in pilot plants and subsequently commercialized. The plant provides acceptable domestic fuel. An 1TPH pilot plant is available at CSIR-CIMFR for testing the coal and coke for briquette making.

The developed technology may provide solutions for waste utilization. Installation of each briquetting plant provides employment generation for about 20 persons, directly and indirectly.
