Sinter Shaft Cooler

The sinter shaft cooler by Primetals Technologies is a revolutionary solution for shaft-based sinter cooling, designed to address the challenge of cooling in the steel industry. This system focuses on enhancing efficiency, reducing emissions, and optimizing energy recovery.

The sinter shaft cooler by Primetals Technologies is engineered to minimize environmental impact while maximizing operational efficiency. A standout feature of this system is its ability to achieve significant emission reduction and up to 100% energy recovery. By employing a counter-flow cooling principle, the system ensures that cooling air passes through the sinter bed in a counter-flow direction, enabling direct heat transfer from the hot sinter to the air. This process maximizes thermal energy utilization, such as steam and electricity generation or preheating and drying operating mediums in the iron and steel plant.

The shaft-based sinter cooling system incorporates advanced dust control measures, minimizing air leakage and effectively reducing dust emissions. This ensures compliance with stringent environmental regulations and contributes to a cleaner, safer working environment. The design of the sinter shaft cooler ensures uniform cooling, maintaining the desired physical and chemical properties of the sinter, which are crucial for efficient blast furnace operation.

Additionally, the system is designed for ease of maintenance and operation. Its robust construction and high-quality materials ensure long-term reliability and minimal downtime, making it an ideal choice for steel producers aiming to optimize production processes and reduce operational costs. The sinter shaft cooler also offers the possibility of replacing circular sinter coolers, contributing to significant CO₂ reduction.
