Overview of Sulfur Combustion Device (Sulfur Furnace) in Bromine Extraction Equipment
Technical Characteristics
Adopting a unique main and auxiliary combustion chamber structure separated by multiple flower walls, the furnace chamber is divided into 1 main combustion chamber and 2 auxiliary combustion chambers .
The flower walls are equipped with air vents, which make the sulfur particles flow in a curve, extend the combustion path and residence time, and ensure complete combustion of sulfur with a combustion rate of 100% . This completely avoids the generation of sublimed sulfur, prevents clogging of subsequent bromine extraction equipment, and maximizes the production of sulfur dioxide (SO₂) required for bromine extraction, realizing zero waste of raw materials and laying a foundation for cost reduction and efficiency increase.
3.Waste Heat Recycling, Significant Energy Saving
Sulfur combustion can generate high-temperature flue gas of about 800℃, and each kilogram of sulfur can release huge heat . We are equipped with an exclusive heat exchanger, which recycles the waste heat of high-temperature sulfur dioxide and directly uses it for chlorine gas vaporization, absorption liquid heating and bromine distillation . It can completely replace external steam, eliminating the need for additional heat sources such as coal, reducing coal consumption by 0.3 tons per ton of bromine, and truly achieving energy conservation and consumption reduction, which conforms to the global green production trend.
4.Equipped with a frequency conversion screw feeder, it can flexibly adjust the sulfur feeding amount according to the bromine extraction capacity and bromine content in brine . Combined with roots blower, it can accurately control the air-sulfur ratio, ensuring complete combustion of sulfur . It can stably output qualified sulfur dioxide without additional equipment modification, adapting to different brine conditions and production scales.
5.Corrosion Resistance & Durability, Stable Operation with Less Failure.The furnace body adopts a carbon steel shell, lined with high-strength refractory bricks and insulation layers .
