Thyssenkrupp to supply handling systems for power plants

(Posted on 26/07/18)

Thyssenkrupp has won a contract from Doosan Power Systems India (DPSI) to supply material handling plants for two thermal power projects in Uttar Pradesh, India. The order is worth a total of around USD 115 million and includes engineering, delivery and installation of two complete coal handling systems, including associated structural and electrical works. The plants will be part of the Obra C and Jawaharpur coal-fired power stations in Northern India, both to be operated by Uttar Pradesh Rajya Vidyut Utpadan Nigam Ltd. (UPRVUNL) and executed by DPSI. Once operational, they together will produce 2,640 MW of power – enough to supply roughly 16 million Indian homes.

With the rapid social, economic and industrial development of the country, demand for electricity in India is increasing continuously. The state of Uttar Pradesh is India’s largest province with a population of nearly 200 million. The new thermal power plants will not only help electrify the surrounding area but also contribute to the central electricity grid and therefore help keep up with the ongoing pace of development in the country.

Malay Das, Managing Director and CEO of thyssenkrupp Industries India: “In India, thyssenkrupp has more than 40 years of experience in material handling technology and the execution of coal handling plants. We are very proud to put this experience to work with DPSI for the Jawaharpur and Obra C power projects. Our innovative and reliable technologies combined with a strong local setup that provides engineering excellence as well as commissioning expertise were key factors in winning this contract.”

Integrated solution for efficient material handling

Effective material handling systems must be individually designed and fully integrated so as to achieve a smooth flow of material from one section of a plant to the next. To meet these requirements, thyssenkrupp will take care of the whole value chain from engineering to procurement and construction for the complete material handling system. From coal unloading and conveying to crushing and storage all key equipment will be manufactured in the company’s own facilities in Pune and Hyderabad.

The scope of supply includes numerous belt conveyors with an overall length of 17 kilometers, four twin wagon tipplers, screens and crushers as well as four combined bucket wheel stackers/reclaimers and one bucket wheel reclaimer. Both systems with an overall coal handling capacity of 3,000 tons per hour each will be fully operational by the first half of 2021.

Coal will be delivered to the site by rail either to a track hopper area or a rail car unloading station which will be equipped with two twin wagon tipplers each. A belt conveyor system with a capacity of 3,000 tons per hour and two meters belt width transports the coal to the crushing and screening complex equipped with a total of four ring granulators and four vibrating screens each. Two combined bucket wheel machines stack the processed coal to the stockpile. When needed the material is reclaimed and transported to the boiler plant on belt conveyors. The stockyard machines will be capable of handling 3,000 tons of coal per hour both in stacking and reclaiming modes.
