The Union Minister of Science and Technology and Earth Sciences, Dr. Harsh Vardhan inaugurated the DME fired “Aditi Urja Sanch” unit along with the DME-LPG blended fuel cylinders and handed them over for common public and CSIR-NCL (National Chemical Laboratory) canteen use on a trial basis at CSIR-NCL premises virtually through video-conferencing.

Key-Points
Dimethyl ether (DME) is an ultra-clean fuel.
CSIR-NCL has developed nation’s first kind of DME pilot plant with 20-24Kg/day capacity.
The conventional LPG burner is not suitable for DME combustion as DME density is different than LPG. To address this issue, CSIR- NCL’s “ADITI URJA SANCH” has come up with a helpful, innovative setup. The new Burner is fully designed and fabricated by NCL for DME, DME -LPG blended mixtures and LPG combustion.
Salient features of newly designed Burner are:
- The new design is efficient for both DME and the blend of DME and LPG.
- Novel design and flexible air ingress.
- The new nozzle design allows optimum oxygen ingress for combustion
- The angles at which nozzles are placed maximize the heat transfer area across the utensils.
- Optimum flame velocity can be obtained.
- The length of the flame (high, low, and medium) can be adjusted by altering the oxygen ingress.
- The experiment shows that it increases the heat transfer rate as well.
