2010/1/1 · Controlling excess combustion air and unburned carbon losses is the key to finding the sweet spot in this biomass boiler approach. Bagasse, a renewable biomass fuel, is the fibrous residue remaining after sugarcane stalks are crushed to extract their juice. Bagasse typically generates 3,000 to 8,000 Btuh/lb of fuel, depending on moisture content.

Bagasse leaving the mills with 50% moisture is fed directly into the boiler as fuel. Maximum energy loss (23.021%) as well as maximum exergy destruction (68.219%) is found in the boiler furnace. The fuel moisture alone accounts for 11.89% energy loss due to the absorption of huge portion of combustion heat for its vapourization.

2021/9/27 · The work presents a theoretical analysis of power generation based on supercritical steam generated by a boiler operating with high-pressure combustion chamber and consuming biomass-water slurry. Steam generated at 30 MPa is injected into turbines and reheated before proceeding to the second turbine stage. The high-pressure flue gas leaving the boiler is used to reheat that steam, and thus

A new 150 tph dual fuel (bagasse/coal) boiler was commis sioned in early 1984 at Tongaat-Hulett Sugar's Maidstone mill. Continuous operation for nine to ten months of the year and substantial energy exports (as bagasse, steam and electricity) from this factory led to the incorporation in the new boiler of a number of novel features likely to have application elsewhere.
