The generation of sulfur dioxide from burning elemental sulfur has a wide range of applications not only in the pulping industry but also in diversified industries from wet corn milling to soap manufacturing. The A. H. Lundberg Associates, Inc. system is suitable for all of these applications. The size of the system is suited to the mill application, and the range of sizes offered is from 1 ton per day sulfur dioxide to above 60 tons per day.

The Lundberg Associates system can melt solid sulfur or utilize molten sulfur.

The molten sulfur is combusted in a pressurized chamber using atomizing air. This results in a high combustion temperature as well as a high sulfur dioxide concentration, thus minimizing sulfur trioxide generation. The combustion products may be cooled for absorption into water or a caustic solution. Furthermore the hot sulfur dioxide gas may be air quenched and sent to a sulfuric acid plant.

The system is designed for complete automation so that changes in the sulfur dioxide demand are compensated for directly in the amount of sulfur burned. The system is operated under pressure so that an induced draft fan is not required in most applications.
