ALGLASS FC VM 500 BURNER

The ALGLASS FC VM burner is a non-water-cooled oxy-fuel burner especially designed for continuous melting furnaces. This burner is particularly appropriate for most glass-type applications. The ALGLASS FC VM burner uses a design (Patent pending) where fuel and oxygen mix outside the burner block. Fuel and oxygen are introduced into the furnace through a unique configuration of injectors that produces a highly luminous flame up to three times wider than conventional oxy-fuel burners. The fuel is distributed, at the bottom of refractory burner block, among three double concentric injectors arranged in a fan-shaped configuration, so that the streams of fuel form a wide sheet of gas in the furnace. Oxygen is injected at lower velocity from two injectors located at the top of the block, that direct the oxygen flow towards the jets of fuel. The use of double concentric injectors with inner injection (high momentum) and outer injection (low momentum) and a built-in valve positioned upstream of the natural gas lance allow to tune the momentum of the gas stream between low momentum (outer injection) and high momentum (inner injection). This design is used to adjust flame shape and more generally combustion characteristics.
