TSI Inc. products

TSI supplies a variety of burners for their dryers. This includes Gas Burners, Fines Burners and Reciprocating Grate Furnaces. These are usually directly connected to the dryer & controlled as part of one integrated system. A Fines Burner will burn wood dust in a cyclonic cloud and can be supplied in single or staged combustion iterations. The furnaces burn wet bark on a stepped grate that moves the fuel across the grate area as it burns, then automatically de-ashes the grate. For the furnaces TSI has partnered with Sigma Thermal Inc. The Sigma Thermal engineers have a long track record of designing and building some of the largest furnaces seen in our industry. They bring that technical expertise to TSI projects and share in the manufacturing and installation of the systems to ensure seamless performance.

Torrefaction is a new twist on an old process that roasts wood chips (or other biomass) in a low oxygen environment. This boils off volatiles and low energy density elements such as hemicellulose to leave a visually darker wood chip that has a higher energy density than regular wood and a natural resistance to moisture. Applications for this product are still developing, but include High Energy Pellets, Gasification, Biofuel Feedstock and Advanced Materials. The TSI process is a patented system based on a rotary drum. The heat energy is produced by indirectly heating the gas that circulates through the system. The process produces a form of Syngas that is ducted back to the burner and can make the process auto-thermal.
