First hot coke charged in Jamshedpur coke dry quenching unit, says Paul Wurth

Paul Wurth has announced that the first hot coke charged into Tata Steel’s CDQ#11 coke dry quenching unit at the Indian steelmaker’s integrated steel plant in Jamshedpur, India, took place in the spring of this year (2018).

The contract for the work was signed in March 2015 and awarded to Paul Wurth as part of a consortium set up with Larsen & Toubro as construction partner.

Paul’s Wurth’s involvement concerned engineering, supply of technological equipment, training and supervision of erection and commissioning for two new coke dry quenching (CDQ) systems.

According to the Luxembourg-headquartered Paul Wurth, while the biggest part of supply volumes and the overall project management was handled by the company, it’s Japan-based JV Paul Wurth IHI provided ‘key technological items and the related expertise’.

After the successful heating-up phase, activities proceeded smoothly, as per project schedule until the first quenching operation on coke coming from coke oven battery (COB) No.11. The second CDQ system is likely to handle coke from COB10 and shall be put in operation during H2 2018. Hot coke throughput capacity will then be 2 x 100 tons per hour. At both CDQ systems, the volume of the main chamber is 500 m3while the pre-chamber capacity is 300 m3
