High Efficiency Biomass Boiler Bagasse Fired Boilers For Sugar Mill Cogeneration

High-Efficiency Bagasse Fired Boilers for Sugar Mill Cogeneration

Usage and Application

The bagasse-fired boiler is a highly specialized thermal solution engineered primarily for the sugar and paper industries. Bagasse, the fibrous residue remaining after sugarcane stalks are crushed, is a phenomenal renewable fuel source, but its extremely high moisture content requires purpose-built combustion dynamics. By efficiently burning bagasse, sugar mills can achieve complete energy self-sufficiency—powering the crushing equipment via steam turbines and exporting excess megawatt-hours to the local grid. For international EPC contractors developing captive power plants or large-scale cogeneration facilities in major sugar-producing regions, integrating a high-reliability bagasse boiler is the most critical step in maximizing the plant's overall commercial return.

Technical Advantages Our bagasse boilers are engineered to handle high-moisture fuels while maintaining exceptional thermal efficiency. They are designed as high-temperature, high-pressure, natural circulation units with a single steam drum. Depending on your spatial requirements, we provide both indoor and outdoor layout configurations.

To ensure continuous, uninterrupted combustion, the furnace utilizes a full-suspension film water-cooled wall structure. The lower firing area can be equipped with either highly reliable fixed grates or advanced water-cooled vibrating grates, supported by a balanced ventilation system. For our heavy-duty 170 t/h models, the boiler features a unique II-type structure consisting of two vertical wall flues. The front shaft houses the fully suspended membrane water wall, while the tail shaft acts as a bearing structure arranging the crossed economizer and tubular air preheater. This strategic arrangement prevents the severe ash fouling typically associated with fibrous agricultural waste.

Frequently Asked Questions (FAQ)

• How does the boiler handle the high moisture content of bagasse? Bagasse often contains up to 50% moisture. We counteract this by utilizing advanced tubular air preheaters to significantly raise the temperature of the primary combustion air. This highly heated air rapidly dries the bagasse as it enters the furnace, ensuring rapid ignition and stable burning on the grate.

• Why use a full-suspension film water-cooled wall? A membrane (film) water wall ensures a completely gas-tight furnace seal, preventing cold air leakage into the combustion zone. The full-suspension design allows the entire boiler structure to expand downward safely as it heats up to extreme operating temperatures, preventing structural warping and cracking over decades of use.
