Getting to the right solution for a rotary hearth furnace
With a thorough understanding of the furnace operations, Air Products engineers identify bottlenecks and develop a customized solution to deliver results.
Issue: A company with a large rotary hearth furnace approached Air Products wanting to buy two oxy-fuel burners.
Solution: Wanting to deliver the best solution, not just make a quick sale, Air Products applications engineers engaged the customer’s operations and plant personnel to better understand the challenges they were trying to solve and to determine if they were using oxygen safely and efficiently. With a combination of our combustion experience, time at the customer facility, computer modeling, testing in our combustion lab, and mass and energy balances, we were able to understand the bottlenecks in the customer’s process. Our solution involved a combination of burners, oxygen enrichment and direct oxygen injection in different zones of the furnace. We installed temporary flow controls, burners and injectors, and demonstrated the benefits of our solution—allowing the customer to quantify the significant productivity and product quality benefits and cost savings. Based on these results, the customer decided to implement oxygen on a permanent basis.
