Abstract
China has already put forward one of the important targets for saving energy and reducing emissions in the iron and steel industry, then the efficient recovery and the full use of the waste heat can become the breakthrough of the further energy-saving iron and steel production. According to the difference between characteristics and quality of the waste heat in the Sintering process, the paper firstly puts forward the technical schemes which include the integrate recovery and steps utilize of the sintering hot gas and waste heat to power generation, then studies the foundation which involved the gas-soild heat exchange and the steam parameters optimize and so on, and also develops the key technology. The results provide a theoretical basis for the improvement of the waste heat power generation device, and also give technical assurance for saving energy and reducing emissions in the iron and steel industry.
