COMPARISON CHART Of FURNACE OIL VS COAL GASIFICATION

Basis of Calculations
qF.O. Consumption/Hr   : 100 Liters
qDaily running Hours   : 24 Hrs
qTotal F.O. consumption/day   : 2400 Liters(100 Liters X 24 Hr)
qRate of F. O.   : Rs. 24.00 / Liter
qMax. Temperature in  rotary  Kiln        : 750 – 900 deg C
qC.V. of  Wood ( Avg )      : 3000 K.cal/kg
qRate of coal (Approx.)   : Rs. 2.5/ Kg   (Including Transportation)
qRate of Electricity   : Rs. 5/KW
qRate of trained Operator on daily wages   : Rs. 300/day
qRate of un-skilled labor on daily wages   : Rs. 150/dayAnalysis of proposed project against Oil firing
1.   Total F.O. consumption/day   :  2,400 Lit/Day
2.   Cost of  FO requirement/day   : Rs. 57,600/-:: 2400 Liter X Rs. 24
3.   Requirement of wood  to replace 1 lit FO              : Max.3.5 Kg/Lit FO
4.   Total wood requirement/day   : 8400 Kg/Day:: 2400 Liter X 3.5 Kg
5.   Cost of  wood /Kg      : Re.2.5/Kg
6.   Total cost of Wood            : Rs. 21000 /day:: 8400 Kg X Re.2.5/-
7.   Gasifier operating cost/day/plant
a) Power…………………   : 50 KW:: 35 KW X 24 Hr X Rs. 5    = Rs. 4,200/day   b) Labor …………………   : 6/Shift, total 18::Total 18 X Rs. 150   = Rs. 2,700/day   c) Operator …………….   : 1/Shift, Total 3::Total 3 X Rs. 300    = Rs.   900/day   d) Maintenance   There is no daily maintenance but annually we take    approx. Rs. 2,00,000/annum, so      Rs. 2,00,000/300 days   = Rs.  666/day,  or say Rs. 700/-   Gasifier operating cost/day/plant= Rs. 8,500/- day   (a+b+c+d)
Gasifier operating cost/day       : Rs.8,500/day  
8.   Total replacement cost/day   : Rs. 29,500/-:: 6 + 7 = 8
9.   Gross benefits /day   : Rs. 28,100/-:: 2 – 8
10.Gross benefits/months   : Rs. 7,02,500/-:: Rs. 28,100/- x 25 days in month
11. Annually Gross Benefits            : Rs. 84,30,000/- :: Rs.  7,02,500/- x 12 Months
12. Total Project cost (approx.)   : Rs. 53,00,000/-   ::   Capital cost of Gasifier + other expenses of pipeline, burners,   Civil, electrical & plumbing works, Lab, cooling tower,    transportation, crane charges etc.  
13. Interest @ 12% pa on total Project cost   : Rs. 6,36,000/-
14. R.O.I.    :  8 ^1/2 MONTHS
