Energy Saving Opportunities in Thermal Energy:

1. Thermic Fluid heating system consumes app. 11000 Liters of HSD per month which is

equivalent to 114, 015, 000 Kcal of heat equivalent to 132,575 KWH per month.

2. Thermal Efficiency the TFH-3 is measured as 78.27%. Overall combustion Efficiency observed
as 82.27%. which is lesser than standard combustion efficiency (Range should be 90-93% in
case of liquid fuels).

1. Major reasons found for the lowered efficiencies are,
a. Improper air to fuel ratio. Observed to 11.4% and should be near to 14%.
b. Carbonization inside thermic fluid pipe line which calls for excess running of

pumps & creates excess pressure drops.
c. Suit formation (Stack temperature is very high in the range of 280-290°C) due to
incomplete combustion of fuel.
2. Opportunities for conservation :
a. By improvement in thermal efficiency within the range of 85-90%, overall saving of
possible App. 150,000 AED Per annum (Data needs to be validated since monthly
consumption data is not clear to us, we have measured the data online and have
concluded).
b. Optimization of Output temperature of process side which will directly give saving.
For further steps for improvement, refer the detailed report and action plan.

(If management agrees to work on the thermal energy conservation, detailed study /
audit is required).

Other Observations

1. During audit we did not find earthing. We have round around the plant. No.of existing
earth pit are not addiquate for the total no. machines.
2. We recommended that detail study is requiring for assessment of actual no. of earth pit.
3. It also observed that existing earth pit not connected in grid, for safety of human &
company
4. Properly all earth pit should be connect in grid (Existing + Proposed).
5. It’s recommended that there should be two fit empty space around panel is needed for
proper preventive maintain work, presently panels only approachable from front side.
