In a sugar mill, steam is used primarily for generating power, concentrating sugar juices, and drying sugars. The economic viability of the cane sugar mill largely depends upon the use of bagasse as a fuel to generate power and process steam. Otherwise, the other biomass fuels (wood, straw, etc.) could also be used to decrease the cost on boiler fuel. Oil and gas fuel could also be used in sugar mill, it has the advantages of no pre-treatment, burnt constantly, high combustion efficiency, etc. Sitong Boiler designs different types boilers that could burn different fuels, and also could customize the specific boiler based on the users’ requirement.
Uses of Boiler & Steam in Sugar Mill
Types and Specifications of Boiler Suitable for Sugar Mill
SZL Biomass Fired Chain Grate Steam Boiler
Capacity: 0.5~25t/h
SZL double drum boiler adopts membrane wall and automatic feeding system, has the advantages of high thermal efficiency (97%), sufficient output, high steam quality, and low pollution. During the paper processing, there are large amounts of waste materials, biomass fired boiler could use these wastes as fuel, save cost.
WNS Horizontal Type Oil Gas Fire Tube Steam Boiler
Capacity: 1~30 t/h
Fuel: heavy oil, diesel, natural gas, LPG, city gas, coke gas, etc.
WNS series steam boiler smoke gas three pass and wet back structure, achieve high thermal efficiency (98%) . This is fire tube boiler, low water quality requirement, the failure rate is lower than 0.1. Adopts international excellent burner, PLC automatic control cabinet, and safety interlock device, operate safely and conveniently.
Coal/Biomass Fired Circulating Fluid Bed Boiler
Capacity: 6~220t/h
Fuel: coal, wood, bagasse, straw, rice husk, and other biomass fuels.
Circulating fluid bed boiler is a large capacity boiler, the new type boiler makes big breakthrough on the technology of cyclone fluid combustion, cyclone separation structure & parametric design, and loop seal device. This series boiler has the advantages of energy saving, high thermal efficiency, sufficient output, and high steam quality.
Price of Sugar Mill Boilers
The price of sugar mill boilers is based on the capacity and accessories. Generally, the accessories of boiler include burner/grate, electric controller, steam header, water softener, BFW pump, platform ladder, and chimney, etc. If you would like to use the specific devices (brand, materials, quantity, etc.) or the additional equipment (air preheater, economizer, condenser, etc.), the prices are quite different. So, if you would like to get the exact price, please inquire for the details.
How to Select a Proper Boiler for Sugar Mill
1. Determine the capacity of the boiler. The boiler capacity should based on the Heating Load Curve or Heat Balance Diagram, and includes the heat loss in pipelines, self-used heat of boiler room, available used waste heat. While, usually, it is difficult to get the Heating Load Curve, the heating load could get based on the max thermal consumption per hour within production/heating/domestic, and then determine by using the coefficient.
2. Determine the boiler heating parameters, including pressure, temperature, etc.
3. Determine the boiler efficiency. In order to benefit for economic management, the boilers should have high thermal efficiency, and the boiler output, quantity and other performances have to adapt to the change of heat loading.
4. It is better to select the boilers with same capacity or combustion equipment. If different, the max limitation is two models, to decrease the problems of equipment layout and management.
