Розробка перспективних систем утилізації теплових вторинних енергоресурсів доменного виробництва

Abstract

The application of the metal hydride systems of the low potential waste heat recovery of the blast furnaces regenerative heat exchangers for the further increase of the efficiency of fuel use in the blast furnace technological processes is suggested. The models of the waste heat recovery power and technological plants for the production of thermal and electric power and refrigeration at the cost of flow gases waste heat are developed. The analysis of the suggested hydrogen energy conversion plants using the research methods based on the exergy functions is carried out. The main characteristics of the power plants hydrogen circuit in the range of flue gas temperatures 523–723 K are determined.
