The objective of this work is to identify the thermal efficiency of the Glendon reactor from a steel company in Minas Gerais, Brazil. The more efficient the equipment, the greater the exploitation of supplied energy and also the smaller the consumption of vegetable coal in a blast furnace, reducing OPEX. This work was a case study based on the analysis of different bibliographical references and by previous studies and real data. The Glendon studied presented a thermal efficiency of 53.1%. More recent studies showed an efficiency of 67.4% using baffles inside the Glendon by changing the gas flow. The fuel used in the Glendon is top-recovered gas from a blast furnace. The energy from the combustion represents 89% of the power input in the regenerator. It was observed that 45.5% of the energy escapes via combustion gases at the chimney.
