BJCEEE has been providing CDQ equipment adopted from Nippon Steel Engineering with a number of independent intellectual property rights, with all-round service ability on design, equipment supply, construction quality management, commissioning and operation & maintenance guidance. The reliable equipment and engineering technology management ability has been highly praised by customers.

They are suitable for various types of general layout of coke ovens (single or double arrangement). In the past, it is difficult to build CDQ for some coke ovens due to limited space, but now, such difficulties have been solved by using the translational typed rotary and rectangular buckets independently developed by us.
