COMPARISON CHART Of FURNACE OIL VS COAL GASIFICATION

Basis of Calculations



q  F.O. Consumption/Hr                                                          : 100 Liters

q  Daily running Hours                                                            : 24 Hrs

q  Total F.O. consumption/day                                                 : 2400 Liters
(100 Liters X 24 Hr)

q  Rate of F. O.                                                                         : Rs. 24.00 / Liter

q  Max. Temperature in  rotary  Kiln                                        : 750 – 900 deg C

q  C.V. of  Wood ( Avg )                                                              : 3000 K.cal/kg

q  Rate of coal (Approx.)                                                            : Rs. 2.5/ Kg
     (Including Transportation)

q  Rate of Electricity                                                                : Rs. 5/KW

q  Rate of trained Operator on daily wages                                : Rs. 300/day


q  Rate of un-skilled labor on daily wages                                 : Rs. 150/day




Analysis 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
