Updating cupola technology pays for itself in savings

Air Products' oxygen tuyere injection system dramatically reduces coke costs for company with large iron cupola.

Issue: Air Products approached a company with a large iron cupola and found out their coke rate was well above the industry average and that they were utilizing some outdated operating techniques.

Solution: Traveling to their plant to better understand their operation, Air Products applications engineers were able to confirm that the facility could realize significant savings by upgrading to an Air Products oxygen tuyere injection system. Our equipment engineering team worked with the on-site maintenance and project team to design a system to fit their cupola and operating conditions. Once installed, we performed a full-service startup and worked with the cupola operators to optimize the system. The result was more than enough savings on coke costs to cover their entire oxygen bill, as well as optimization and productivity improvements.
