In the sugar cane sugar production process, the plant produces approximately 2 tons of bagasse per ton of white sugar produced. The cane sugar plant can use these bagasse as fuel for boilers, and generate steam for production as a source of energy for sugar production.
Previously, bagasse was burned as a means of solid waste disposal. However, as the cost of fuel oil, natural gas, and electricity has increased, bagasse has come to be pursue as a fuel rather than refuse. In general, bagasse has a heating Value between 3,000 and 4,000 British thermal units per pound (Btu/lb). Most bagasse has a moisture content between 45 and 55 percent by weight.
If bagasse is not ideal during the combustion process, it will generate a lot of smoke and pollute the environment. According to the burning characteristics of bagasse fuel, ZBG specializes in designing boiler structure parameters and combustion methods to achieve environmental protection, improve resource utilization and reduce production costs.
ZBG Distillers Bagasse Biomass Boiler is a professional boiler designed for this kind of fuel. It has the advantages of reliable water circulation, high efficiency combustion and low pollution discharge. The boiler downcomer is arranged at the four corners of the boiler, not only as a water circulation channel, but also as a support frame for the boiler. The drum is external, the furnace is a fully enclosed membrane wall structure, the convective heating surface adopts a gas tube structure, no steel frame, the water cycle is unique and safe, and the startup is rapid.
The boiler adopts a secondary air double-layer grading arrangement with low resistance, high momentum and strong penetrating force to further suppress NOx formation while ensuring combustion and desulfurization effects. At the same time, the boiler overcomes the defects of wear, clogging of the returning device, high concentration of the original dust, and difficulty in slagging. The boiler has reasonable structure, excellent performance and safe and reliable operation.
