Abstract

PROCESSO E APARELHO PARA COMBUSTãO COM BAIXO TEOR DE -NO~x~. A invenção refere-se a um processo e a um aparelho para a combustão com baixo teor de NOx, com, pelo menos, um queimador (5) que utiliza combustível e agente oxidante e/ou gases de queima do forno e/ou diáxido de carbono e/ou vapor. A combustão com baixo teor de NOx, de acordo com a invenção, pode ser utilizada em fornos convencionais de fusão e/ou de espera, em particular em fornos de espera em alumínio ou fornos de tambor giratório e fornos de fusão de vidro,com potencial para que sejam feitas economiasconsideráveis.LOW FUEL PROCESS AND APPARATUS -NO ~ x ~. The invention relates to a process and apparatus for low NOx combustion with at least one burner (5) using fuel and oxidizing agent and / or furnace and / or dioxide burning gases. carbon and / or steam. Low NOx combustion according to the invention may be used in conventional melting and / or holding furnaces, in particular in aluminum holding furnaces or rotary drum furnaces and glass melting furnaces with potential so that considerable savings are made.
