In May 2022, Metso Outotec launched the new generation Converter hood system. The product launch was the first step in marketing of the new Converter hood system. After the product launch, the market has shown a big interest in our new system.

Here at Metso Outotec, we understand our customer’s world and the daily challenges they face. To resolve these issues, our new system addresses the three main challenges that customers are facing today, which include:

  • Environmental performance
  • Installation and maintenance
  • Lifecycle cost

A reliable and properly designed Converter Hood System is essential for maximum efficiency of capturing process gas and avoiding gas emissions during converter operations. The new Metso Outotec Converter hood system fulfils these requirements.

Our system optimizes the gas temperature for equipment downstream in the gas system, gives suitable off-gas composition to the sulphuric acid plant and ensures that no excess gas volume needs to be handled by the gas cleaning system. This gives a maximized gas capturing efficiency during the whole converter cycle, as well as excellent environmental performance. This is also essential in establishing good occupational safety and health.

The new Metso Outotec Converter Hood System is a modular system, designed and manufactured to minimize down time during installation, and with minimum need for maintenance. The modules in the system are manufactured, assembled and tested in factory before shipment to the customer. All manufacturing steps are performed in a controlled environment in the factory, minimizing the need for site activities, such as assembly welding of critical parts and performing FAT tests. This ensures a high-quality product with minimal installation time.

The design and control of the new Metso Outotec Hood cooling system maximizes energy saving and optimizes the operational conditions for the Primary converter hood during the whole converter cycle. This ensures a long lifetime for the equipment, and will - together with the short installation time – result in a low lifecycle cost.

Metso Outotec are constantly seeking to develop our products and technologies. With our new generation Converter hood system, we have taken a step in developing the Converter aisle performance and environment. Our next step will be to ensure that our system continues to develop, especially in line with the Metso Outotec overall digitalization strategy. With our strong R&D and innovation power, we are continuously looking for new ways to introduce innovations for our customers’ benefit. That’s why, together, we are the partner for positive change.
