Description
Изобретение касаетс способа введени топлива в печь дл доменной возгонки фосфора.The invention relates to a method for introducing fuel into a furnace for blast sublimation of phosphorus.
Применение дл этой цели р да низкокачественных местных топлив при обычном способе подачи топлива в домну через колошник невозможно, в виду нарушени хода доменного процесса, спекани и зависани шихты , соединени фосфора с летучими част ми топлива и т. д.It is impossible to use low-quality local fuels for this purpose with the usual method of supplying fuel to the blast furnace through the throat, due to disruption of the blast furnace process, sintering and freezing of the charge, phosphorus compounds with volatile parts of fuel, etc.
Предлагаемый автором насто щего изобретени способ позвол ет заменить очень значительную часть кокса , примен емого при доменной возгонке фосфора, почти любым низкокачественным топливом (например, торфом, подмосковным углем, даже горючими сланцами и т. п.).The method proposed by the author of the present invention makes it possible to replace a very significant part of the coke used in the sublimation of phosphorus with almost any low-quality fuel (for example, peat, coal near Moscow, even combustible shale, etc.).
Предлагаемый способ состоит в том, что в колошник домны вводитс и смешиваетс с фосфатной шихтой лишь некотора часть всего расходуемого топлива (в виде подход щего дл домны топлива, например, кокса). Остальна часть топлива, в виде низкокачественного топлива, вводитс не через колошник домны, а через вспомогательную трубу непосредственно в нижнюю часть домны , над фурмами, в зону горени . Подача топлива по этой трубе может производитьс , например, щнеком или другим способом.The proposed method consists in introducing and mixing with the phosphate mixture into the top furnace of the furnace only some part of the total consumed fuel (in the form of suitable coke for coal, for example, coke). The rest of the fuel, in the form of low-quality fuel, is introduced not through the furnace top, but through the auxiliary pipe directly into the lower part of the blast furnace, over the tuyeres, into the combustion zone. The supply of fuel through this pipe can be effected, for example, by a jaw or other means.
Топливна труба может быть или вертикальной, проход щей через колошник домны по ее оси, или же наклонной сверху вниз, проход щей через боковую часть домны до ее центра, в зоне горени , над фурмами. В последнем случае топливную трубу можно, во избежание затора шихты над ней, делать вращающейс эллиптической или же придавать ей суженную и заостренную кверху форму.The fuel pipe can be either vertical, passing through the furnace top along its axis, or inclined from top to bottom, passing through the side of the furnace to its center, in the combustion zone, above the tuyeres. In the latter case, the fuel pipe can, in order to avoid mash of the charge over it, be made rotating elliptical or give it a narrowed and pointed upward shape.
Дл лучшего сжигани вводимого по топливной трубе добавочного низкосортного топлива можно подводить по концентрической с ней трубе гор чее воздушное дутье. Трубу дл воздушного дуть не следует доводить до самого конца топливной трубы или же ее нужно делать с боковыми отверсти ми дл выхода дуть . При указанном устройстве трубы лучше идет смешивание дуть с топливом.In order to better burn additional low-grade fuel introduced through the fuel pipe, a hot air blast can be supplied along the concentric pipe. A pipe for air blowing should not be brought to the very end of the fuel pipe, or it should be done with side openings for blowing out. With the specified pipe device, it is better to blend blowing with fuel.
