Abstract

GRELHAS SECADORAS DE INCINERADORES COM CONTROLE DE TEMPERATURA. Grelhas secadoras do incinerador, com controle de temperatura fornecido por um vapor bifásico. Refugo volumoso encharcado que entra em um incinerador e fica em uma grelha antes de cair em piso de forno, abaixo. Esse processo expele os hidrocarbonetos voláteis e conduz á secagem. A grelha pode também fornecer ar combustível. O processo de secagem faz com que o conteúdo úmido do refugo caia para menos de 50 por cento, onde a combustão pode ocorrer. O vapor bifásico passa através de canais separados na grelha para controle da temperatura. O gás contendo oxigênio, emanado da grelha na câmara de combustão contém produtos gasosos da combustão, ou gás de combustão com ou sem ar, para se utilizar o calor do primeiro e do conteúdo úmido. Quanto o gás de combustão contém cloro, a temperatura deve cair com a adição de ar fresco, em uma faixa entre (400<198>F e 750<198>F). Para se evitar a corrosão pelo cloro, caldeiras que empurruam o gás de combustão devem ficar inteiramente afastados do fluxo de gás, ou ter contado somente com o gás somente o gás de combustão, depois resfriado á faixa de temperatura acima citada. Para refugos em partículas ou triturados, uma segunda grelha desemparelhada , embaixo da primeira , deve haver uma pausa, tempo suficiente para que o material seque e os hidrocarbonetos voláteis se evaporem. Um carregador entre no incinerador para empurrar o refugo na grelha e limitar seu volume, de modo que o gás da grelha possa penetra-lo.TEMPERATURE CONTROLLED INCINERATOR DRYING GRILLS. Incinerator dryer grilles, with temperature control provided by a two-phase steam. Soaked bulky waste that enters an incinerator and sits on a grill before falling to the oven floor below. This process expels volatile hydrocarbons and leads to drying. The grill may also provide combustible air. The drying process causes the wet content of the waste to fall below 50 percent, where combustion may occur. Biphasic steam passes through separate channels in the grid for temperature control. Oxygen-containing gas emanating from the grate in the combustion chamber contains gaseous combustion products, or air or non-air flue gas, to use the heat of the former and the wet content. When flue gas contains chlorine, the temperature should fall with the addition of fresh air in a range between (400 <198> F and 750 <198> F). To avoid chlorine corrosion, boilers pushing the flue gas should be entirely away from the gas flow, or have only flue gas relied on the gas, then cooled to the above temperature range. For particulate or crushed scrap, a second unpaired grid under the first should be allowed to stand, long enough for the material to dry and volatile hydrocarbons to evaporate. A charger enters the incinerator to push the waste into the grate and limit its volume so that the grate gas can penetrate it.
