Taking the challenge

John Zink Hamworthy Combustion, is a global supplier for customer orientated solutions. For the IMPROOF project JZHC has taken on the challenge to perform full scale testing of the burners for this project that are to be installed in the cracking furnace. JZHC is responsible for the design of the burners, which shall be capable to operate safely and highly efficient on biofuel gas. In addition, full scale testing with Biogas and under oxyfiring conditions shall be performed at the John Zink Research and development test venter located in Tulsa, Oklahoma.

JZHC is in the possession of a full-scale model test furnace of an ethylene cracking furnace. The test facility allows to test the burners up to full load conditions, and to perfectly judge burner performance at various operating conditions. During testing activities valuable test data like emission performance as well as heat flux of the combustion system will be recorded. This data obtained from the full scale testing will be used to calibrate large CFD models,. These will be developed by other partners, to allow simulating complete cracking furnace accurately under the new combustion situation.
