The chimney gate valve is widely used in the metallurgical industry as a control element in fume extraction systems of the furnace chamber. However, its flow characteristics are not appropriate for controlling this flow. Linear characteristics would be the most appropriate.The aim of this study is to present the problems of control technology in the metallurgical industry – conducted improperly due to many difficulties or lack of knowledge of controlled installation. The chimney gate valve (as an element of control), installed in the heating pusher furnace, is presented in the paper. The proposal to address the identified problems is also presented. The solution is to use a digital control linear setting element which significantly reduces the negative environmental and economic consequences.As a result of the chimney gate valve digital control and the measurement of the exhaust gas pressure in the furnace chamber, a significant reduction in gas fuel consumption and reduction of CO2 emissions have been achieved. The reduction of fuel did not change the technological temperature of the metallurgical process.Keywords: chimney gate valve, heating furnace, CO2 reduction, environmental protection, energy savings
