Babcock has provided a swift and well-engineered desuperheater solution for the Sappi Ngodwana Paper and Packaging Mill.

With more than 120 years’ experience in the steam generation business, Babcock is one of the most established and experienced suppliers in Africa. Supported by best in class technology, the company’s skilled workforce draws on decades of knowledge and experience, enabling Babcock to provide safe, effective solutions for the entire lifecycle of industrial plant, from design and build, through operation and maintenance, to decommissioning and remediation.

Babcock’s engineering business specialises in the front-end design of steam generation plant and associated equipment, construction concept generation and development of potential solutions in a business case environment, while focusing on feasibility of new build options, performance upgrades, efficiency improvements and emissions reductions.

The Sappi Ngodwana project required the replacement of an existing 1 100 kPa desuperheater in the steam plant at Sappi Ngodwana, a vital component in the production capacity of the plant as the majority of the mill processes requiring steam cannot operate if the desuperheater system is faulty or shut down. The desuperheater is a system that is used to reduce the temperature of superheated steam by injecting water into it. The water injection is controlled to reduce the steam temperature within close proximity of the saturation temperature of the steam.
