Acme jumper pipe system for coke-oven charging
- Acme Steel Co., Chicago, IL (United States)
Acme Steel has operated larry cars with an attached jumper pipe since 1977 and had been able to meet the State Implementation Plan (SIP). With the advent of the Clean Air Act (CAA), Acme considered that it could not meet these new standards without modifications to the jumper pipe system. Several drop sleeve modifications, boot seal materials and configurations were tested that resulted in limited success in improving the boot seal life. These modifications showed that the Clean Air Act standards could be met, but it would be cost prohibitive to continue to operate in this manner. The company decided to install an off-car jumper pipe system which uses a traveling U-tube for connection to the assist oven through an additional hole in the roof of each oven. Temperature related failures of drop sleeve seals were eliminated. The off-car jumper pipe is a more efficient gas connection to the assist oven and enables the company to meet the Clean Air Act charging requirements in a cost effective manner.
