Product category: Combustion technology for oil and gas fired melting furnaces
Lambda Control based on Oxygen sensors
STG Oxygen sensors today are representing a wide spread standard in German and European glass industry. Already several melting furnaces are operating more energy efficient with lowered air pollution, using Lambda-Control based on STG sensors.
While ratio control of air and fuel controls only the input, but uncontrolled input of Parasitic air as about 5…10% of total air really decides about efficiency and NOx emission. Only Lambda control may provide you real control of optimum combustion, taking in account the feedback of combustion products.

STG Air Curtain to ensure an optimized distribution of combustion air for block type regenerators without partition walls
If you operate a cross fired furnace controlling the optimum ratio of combustion air for the furnace “in average” it is not enough – you must be able to do it individually port by port. Even if the separating walls between the regenerator chambers are missing, STGs Air Curtain system, using compressed air baffles, is able to provide individual control to optimize the combustion air distribution. By creating an adjustable barrier of compressed air, parts of the preheated air from the port having excess air will be redirected to the neighbouring ports.
