The objective of the study was to develop a concept design for a test non-recovery coke oven, which was required to be relocatable.
The report summarises available knowledge on full scale ovens, the development of estimates for missing information, and the development of final design requirements.
After considering all of the design requirements, it was decided that only a hybrid test oven (with combustion heating above the bed, and electric floor heating) is capable of simulating the unique heating conditions in NRCOs. The hybrid oven also provides the most reproducible heating conditions for research purposes.
Two configurations were studied: C2 with warm gas velocity measurement using precision commercial instruments, and C3 with hot gas velocity measurement using a refractory venturi. Both configurations are capable of simulating the wide range of conditions occurring in current and future ovens. Also, both designs are capable of producing data for predicting the effect of blends and coking conditions on heat recovery (for power generation) from any oven-battery heat recovery configuration.
Designs for both concepts are presented, including general arrangement drawings, equipment list and costs, and control strategies. The drawings are of insufficient detail to enable construction without detailed fabrication drawings and P&ID for the preferred design. The cost of this work is included in the total construction cost estimates.
Estimated overall construction costs, will allowances for the final detailed work, is $418,000 for C2 and $403,000 for C3.
Overall, Concept-3 is recommended as the preferred arrangement due to a number of advantages.
It is recommended that the skid configuration of the design be used to facilitate fabrication, should significantly reduce construction costs and commissioning time, and the cost of producing a duplicate facility.
