All Ecomax burners have an integrated heat exchanger using the exhaust heat to preheat the combustion air to a maximum of 700° C. Fields of application for the self-recuperative burners are indirect heating systems with radiant tubes or direct heating systems in conjunction with an eductor for reabsorbing the flue gases by suction. The Ecomax series consists of a total of seven sizes and covers a capacity range from 25 to 500 kW. The self-recuperative burners are available in metallic, all-ceramic or flat tube versions (M, C or FTR). Thus, Ecomax.C has a ceramic recuperator made of SiSiC for a maximum application temperature up to 1 300° C. The cast steel ribbed tube recuperator of the Ecomax.M ensures a maximum efficiency up to 1 150° C. All Ecomax burners feature direct electrical ignition and, depending on the application, are directly ionization-controlled or monitored by a UV sensor. The extremely high flame outlet velocity and On/Off control ensure precise temperature control and accuracy in the furnace.
Elster Kromschröder is filling a gap in the series of Ecomax ceramic self recuperative burners produced by the LBE business segment. With the new Ecomax 4C, which has a burner capacity of 180 kW, the company is supplementing its range. With its SiSiC recuperator, Ecomax 4C is suitable for directly heated heat treatment processes in which metallic self-recuperative burners either cannot be used or can only be used on a restricted basis. Since the self-recuperative burner utilizes the heat of the furnace flue gases to preheat the combustion air, as do all members of the Ecomax series, it significantly lowers the gas consumption. Energy savings of up to 30% can be made by using an Ecomax, depending on burner model and mode of operation. The systems‘ efficiency is thus increased considerably.
