For Bangladesh brick size of 10*5*3 inches, the total coal needed for firing per pcs brick is about 200-250 g (including adding coal inside of the green brick). That is, you will need 20-25 Tons coal for firing 100000 bricks, 40-45 tons for firing 200000 bricks and 10-12tons for firing 50000 bricks. You can also take biomass briquette (sawdust, rice husk, straw, etc.) as the fuel of Hoffman kiln.
