Abstract

<B>"DISPOSITIVO PARA IMPEDIR A COMBUSTãO INCOMPLETA EM UM AQUECEDOR DE áGUA A GáS"<D>. A presente invenção trata de um dispositivo a combustão incompleta em um aquecedor de água a gás, quando o trocador tanto após a ativação, como em estado contínuo, mediante uma resposta apropriada à anormalidade. Um controlador de queimador (30), aplica uma voltagem a uma haste de chama (38), que é posicionada acima dos orifícios de chama (22) e nas chamas produzidas pelo orifícios de chama (22), sob condições normais de combustão. Após detectar que a chama presente não apresenta um valor maior que um valor inicial predeterminado, o controlador de queimador (30) fecha uma válvula solenóide de gás (26), destinada ao suprimento de gás combustível ao queimador. Um tubo de refluxo (13) é fornecido em uma saia interna (10) que inclui uma seção principal (13a), tendo uma extremidade superior aberta para uma câmara de combustão, abaixo de um trocador de calor (12), que se estende de forma vertical descendente da extremidade superior. O tubo de fluxo (13) é também proporcionado com uma seção de maior diâmetro (13c), conectada à extremidade inferior da seção principal (13a) e aberta na sua base para a atmosfera, fora da saia interna. O tubo de refluxo (13) inclui adicionalmente um tubo de retorno (13b), desviado da conexão entre a seção principal (13a) e a seção de maior diâmetro (13c). O tubo de retorno (13b) se apresenta estendido e aberto na direção dos orifícios de chama, abaixo da haste de chama. Essa configuração minimiza a quantidade de descarga de combustão retornada aos orifícios de chama, por meio do tubo de retorno, após a ignição do queimador.<B> "DEVICE TO PREVENT INCOMPLETE COMBUSTION IN A GAS WATER HEATER" <D>. The present invention deals with an incomplete combustion device in a gas water heater, when the exchanger both after activation and in a continuous state, by means of an appropriate response to the abnormality. A burner controller (30) applies a voltage to a flame rod (38), which is positioned above the flame holes (22) and in the flames produced by the flame holes (22), under normal combustion conditions. After detecting that the present flame does not present a value greater than a predetermined initial value, the burner controller (30) closes a gas solenoid valve (26), destined to supply combustible gas to the burner. A reflux tube (13) is provided in an inner skirt (10) that includes a main section (13a), having an upper end open to a combustion chamber, below a heat exchanger (12), which extends from vertical shape descending from the upper end. The flow tube (13) is also provided with a larger diameter section (13c), connected to the lower end of the main section (13a) and opened at its base to the atmosphere, outside the inner skirt. The reflux tube (13) additionally includes a return tube (13b), deflected from the connection between the main section (13a) and the larger diameter section (13c). The return tube (13b) is extended and open towards the flame holes, below the flame rod. This configuration minimizes the amount of combustion discharge returned to the flame orifices, through the return pipe, after ignition of the burner.
