We have the experience, people, and technology to best meet the increasingly demanding needs of the air heating industry. Fives North American Combustion, Inc. is a world leader in process heating and combustion technology with a long history of providing high quality Hot Gas Generators. Our experience in heating and drying spans a vast array of products including coal, gypsum board, paper, grain, and minerals. Higher temperature applications include calcining and thermal oxidation. Overall we have produced hundreds of hot gas generators in a very wide range of capacities for once through and recirculated process streams. In order to properly integrate the HGG into your system, we analyze the unique and complex relationship between the heated air and the rest of the process in order to understand the requirements for temperature uniformity, heat transfer, efficiency, and emissions. All North American systems are custom engineered to be compact and efficient to meet the specific process needs identified. We welcome the opportunity to provide a cost effective system for you.
• Footprint and capital costs. Many HGG’s builders use very large heaters with long residence time to achieve a moderate level of temperature uniformity. North American's technology allows the most compact designs available – saving factory floor space and capital. • Greenhouse gas. Poor energy efficiency yields unnecessary CO 2 . North American’s improved controls and temperature uniformity provides for a reduction in both .

• Production and energy efficiency. Uneven heat distribution of the process air stream reduces production, produces harmful mechanical stresses and wastes energy. North American’s unique injection mixing method produces exceptional uniformity, in many cases +/- 5% of the target temperature, positively impacting efficiency. Recirculated product gases, as part of the air supply, can improve efficiency and lower emissions. • Emissions. Excessively high NOx, and CO emissions can restrict production. Our Best Available Control Technology (BACT) can reduce emissions to as low as 8 ppm (at 3% oxygen) with no FGR, even with preheated or vitiated combustion air.
