3. Why LPG ?
.1-Clean Burn
2-No Spillage/ No Fumes .
.3-No Pilferage
.4- Higher Efficiency

4. Redesigned system

5. Calculate the amount of heat generated
Q = ṁ * HCV
Q = 3.5/3600 * 43.3 = 42 KW
Q = ṁ * HCV
Q = 10/3600 * 46.6= 129.4 KW
For diesel
For LPG
API

6. Results(Stability or operation window )

7. Flame front lift .
15 CM 10 CM 5CM

8. Conclusion
1- The use of LPG instead of diesel achieved
good economic results.
2- In the issue of stability, increasing the
length of the neck of the burner is useful at
low operating load.
