The VEINAIRFLAM burners are raw gas burners designed for direct-fired fresh air or partially mixed air heating. They are the basic standard for low, middle or semi high temperature (up to 850 °C) make-up applications in many industrial fields. The VEINAIRFLAM burners produce a uniform, odorless, and smokeless flame ideal for heating fresh air in make-up and process air heating applications. VEINAIRFLAM burners design provides stable operation over a wide range of velocities, inputs, and fuels. The VEINAIRFLAM burners design make possible to operate the burner without a combustion air blower. The burner with no moving parts depends on the air speed across the burner from the airflow in the duct. The turbulence effect created by the mixing plates is heightened by provision of a diaphragm air plates accelerating the air speed all around the burner's location. This results in a slight pressure drop in the air to be heated. The pressure drop or pressure loss practically does not exist with the VEINAIRFLAM-V series who is designed with a air combustion blower integrated wich doesn't require diaphragm or profiles plates. The VEINAIRFLAM burners are directly mounted in the airstream to be heated and a specific air velocity is created all around the burner to provide progressive aeration of the space between the burner air/gas mixing plates. The oxygen necessary for combustion is taken directly from the air witch enters through the mixing plates hole's and mixes gradually with the gas. The burner is therefore a burner with a very large excess air for complete gas combustion. 100 % efficiency (on gas Pci). Each component of a VEINAIRFLAM burner consist of a cast iron feed pipe and very high quality stainless steel for high temperature perforated mixing plates. V2 feet & 1 feet linear straight sections, Tee sections and H sections (3 ft) are designed for a mechanical tailor made burner without power limitation. VEINAIRFLAM burners are made from modular components allowing a large number of configurations and make it possible to obtain any desired power rating. VEINAIRFLAM burners up to 50 MW and more over are not impossible. VEINAIRFLAM burners are working with gas at low pressure (only gas, no liquid).
