<p>A burner comprising at least one burner tube (1) having a plurality of gas outlet orifices forming a burner bed. A plurality of plates (8) are extending upwards from the sides of the burner tube within the reach of the flames. These plates, which lower the flame temperature, and promote a staged combustion, are arranged parallel to and on opposite sides of the gas outlet orifices and are directly connected to the burner tube mainly through their lower ends. At least one of the upper ends of the plates is bent outwards, which leads to improved cooling, improved mixing of combustion gas and secondary air and hence to improved combustion. <IMAGE></p> |
