Unburnt Bagasse In Boilers

Trouble Shooting Boilers | Deepankar Mukherjee - …

Unburnt in the ash is less. Where less unburnt is demanded for other uses, Underbed is the only choice. Unburnt is a function of fines in the fuel. The ash will have more unburnt. Excess air required for underbed is less. Usually 20 – 25 % is sufficient to bring

Steam Boiler: Bagasse Ash

From the combustion process will be generated bagasse ash that has gray-black color. If a sugar plant operates 3 boilers need about 51 tons of bagasse per hour, so one day it takes about 1224 tons of bagasse which is used as fuel for these boilers. Assuming bagasse ash has proportion of about 2% of the bagasse…
