Almost every day, from different information source, we can hear about problems dealing with CO2 emission and its impact on environment and us - people. A few sources from which CO2 is emitted can be pointed out but this paper focuses on metallurgical industry. The main areas of interest are furnace process technologies where the gas burners are used. The main product of gas combustion in those burners is CO2, so that in non-optimized combustion processes that emission is very high.Therefore the world-metallurgical industry keeps looking for some solutions for fuel saving and thus CO2 reduction. One of the methods which are used to solve this problem is applying high combustion air temperature. What is more and more attractive is the High Regenerative System (HRS). It can achieve an air temperature of more than 1000 °C. It saves more fuel and it is more environmental friendly. The HRS makes use of the regenerators as heat exchangers. This system has become increasingly popular in the aspect of reducing CO2 emission.Based on research results the paper presents the selected data, dealing with the combustion air temperature obtained for the honeycomb type of regenerator filling. The reduction of both fuel consumption and CO2 emission has been presented finally as an economic and environmental aspect according to the air preheated.Keywords: heat regenerator, regenerative burner, high air temperature, CO2 reduction, environment protection
