Steam Produced = 10000 Kg/hr
No.of days of operation = 350 days
No.of hours of operation = 350*24 = 8400 hrs
Total steam produced = 8400*10000 = 84*106 Kg
Pressure of steam = 15 bar
Boiler efficiency = 80%
1 MMBtu = 28.2636 m3 = 28263.6 Kg;
84*106 Kg = 84000 m3
Fuel (natural gas) required = 84000/(28.2636*0.8) = 3715 MMBtu required per year
Fuel (natural gas) cost = 3715*4 = $ 14860.1 / year
Fixed cost = $ 73000 / year
Raw water cost = Total raw water required * 10-3 * 0.5 =( (84*106) / 0.8) * 10-3 * 0.5 = $ 53750
Maintenance cost = %1 of FCI = $ 730
a)
Total cost per year
= FCI + Fuel cost + Maintenace cost + Water cost = $ (73000 + 14860.1 + 730 + 53750 )
= $ 142,340.1
b)
%Capital cost to total cost = (73000/142,340.1) * 100 = 51.28 %
%Fuel cost to total cost = ( 14860.1/142,340.1) * 100 = 10.44 %
% Water cost to total cost = ( 53750/142,340.1) * 100 = 37.76 %
% Maintenance to total cost = (730/142340.1) * 100 = 0.512 %
