Hauck and LBE are jointly offering the Ecomax® direct-fired self-recuperative metallic gas burners for high temperature furnace applications in the US market. Equipped with an eductor system, the burner is capable of 100% exhaust gas removal.
The high temperature alloy recuperator is designed to allow for maximum combustion air preheat which results in efficiencies up to 70% for maximum fuel savings. Capable of firing any clean industrial fuel gas with a higher heating value of 500 Btu/scf (19.7 MJ/nm³) or greater, the Ecomax® is available in five sizes with capacities from 57,000 to 945,000 Btu/hr (15 to 250 kW) for process temperatures up to 2100°F (1150°C).
Higher temperature and low NOx emissions versions are available.

Advantages
The Ecomax® burner is widely used in the heat treating industry for direct heated roller hearth and batch furnaces. It utilizes preheated combustion air from the furnace exhaust gas allowing the burner to achieve a maximum combustion air temperature of 1490°F (810°C). The energy savings coupled with the burner's simple design and easy installation result in cost effective payback periods.
The burner is constructed with a multifunctional housing through which it is mounted, supplied with air, cooled and exhaust gas is discharged. This makes the burner easy to assemble and install. The housing is constructed of insulated cast aluminum and is double-walled for durability.
The Ecomax® is self-recuperative utilizing hot furnace exhaust gas for preheating the combustion air. The heat resistant alloy recuperator and silicon carbide combustor allow the burner to stand up to the high temperature environment.
The burner's eductor system allows up to 100% of exhaust gas removal. This eliminates the need for a complicated, costly centralized recuperator, insulated hot air piping and the inherent maintenance issues.
The burner is designed for process temperatures up to 2100°F (1150°C) with higher temperature versions available. High exit velocities up to 525 ft/sec (160 m/sec) are achieved resulting in excellent furnace temperature uniformity.
The Ecomax® is designed to operate on any clean industrial fuel gas with a higher heating value of 500 Btu/scf (19.7 MJ/nm�) or greater. The burner is available in five sizes with capacities from 57,000 to 945,000 Btu/hr (15 to 250 kW).
