Fuel Sciences Group


The FS group is working on the Third Party Coal Sampling (TPS) Project in collaboration with the Resource Quality Assessment (RQA) Division of CIMFR Digwadih, Dhanbad. The FS group is capable to provide lab solutions to coal and power companies including the energy audit for many government and private organizations. The workforce of fuel sciences has tremendous exposure to provide deliverables, in terms of laboratory testing, and data analysis work required by various associated coal agencies in India and also for international companies. Following are the major areas of research activities and infrastructure facilities of the fuel science laboratory and the group.

In the past, the FS group had undertaken several important projects of national recognition.  The Indian mining industry is the direct beneficiary of the expertise and FS group is moving ahead with a planned future perspective.







Development of Coal Quality Exploration Technique based on Convolution Neural Network and Hyper spectral Imaging  (Grants-in Aid project)


Ministry of Mines (MOM), Govt. of India


Various projects for scientific study of coal quality loaded from various sidings of WCL & SCCL and unloaded at power utilities. (Mega Coal Sampling Projects)



Various projects  for the quality assessment of coal/lignite seams encountered in the exploratory boreholes drilled by agencies such as GSI, CMPDI, MECL, State departments of Geology & Mines and private agencies in the different blocks of Indian coalfields (Bore Hole Coal Core Analysis Projects)




CSIR-Integrated Energy Audit and Management Collaborative Project (Under Sub-Vertical VI of the energy theme directorate of CSIR; As part of the CSIR-IEAM program). (Energy Management Project)




  1. Strategies to ash fusion temperature (AFT) of foreign-origin coal for optimal use in Indian Thermal power plants
  2. Experiments on the determination of equilibrated moisture (EM) of WCL, SECL, and SCCL Coals to reduce conditioning time from 72 hours to the lowest possible up to 24 hours
  3. To develop and implement RFID based security system for the safety of samples.
  4. Study of the effect of oxidation on chemical properties of coal
