In the case of 50% bagasse humidity, the flame temperature of the burning bagasse may vary from 850 to 920 C and if the bagasse humidity is less than 35%, the flame temperature may reach 1000 C []. A high combustion temperature within the boiler can result in silica crystallization, which eventually leads to poor SCBA pozzolanic activity [ 39 ].

Contribution of cane bagasse used as a fuel in the sugar

1/1/1991 · It is reported (Paturau, 1969) that 1 t of bagasse (49% moisture), as a fuel, is equivalent to 0.18t fuel oil, 0.28t bituminous coal, 0.15t (or 0.209 m3) natural gas or 0.55 t air-dried wood. This reflects the great amounts of bagasse which must be burned in the boiler furnaces in the sugar factories to obtain equivalent amounts of energy.

Improve Your Boiler's Combustion Efficiency

From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300 F. The boiler combustion efficiency increases to 83.1% (E2). Assuming a fuel cost of $8.00

Boiler Combustion | CleanBoiler.org

A boiler's excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.
