Description
Obrotowe piece rurowe do wypalania cementu, magnezytu, wapna i podobnych materjalów, maja te wade, ze przez otwór wyladowczy dostaje sie do wnetrza pie¬ ca nadmiar powietrza, powodujacy spala¬ nie sie wiekszych ilosci wegla, niz potrzeba rzeczywiscie do procesu wypalania. Celem wynalazku niniejszego jest usuniecie tej wady przez uzycie urzadzenia, które jest szczelnie polaczone z piecem i umozliwia regulacje ilosci powietrza, doprowadzanego bez wyzyskania lub tylko z czesciowem wyzyskaniem ciepla spalin i w takiej ilosci, jaka jest potrzebna do procesu wypalania.Jezeli otwór wyladowczy pieca jest szczelnie zamkniety, to nawet bez wyzyski¬ wania ciepla spalin praca jest ekonomicz¬ niej sza, bo doprowadza sie tylko minimum powietrza, potrzebnego do spalania. Nowe urzadzenie moze byc zastosowane do kaz¬ dego pieca obrotowego, nawet w tych wy¬ padkach, gdy wskutek braku miejsca nie mozna wlaczyc chlodnicy. Rozwazanie tych okolicznosci doprowadzilo do wniosku, ze nawet przy czesciowem lub cfJkowitem po¬ minieciu spozytkowywania ciepla spalin, mozna osiagnac znaczna oszczednosc na pa¬ liwie, jezeli ilosc wprowadzanego powie¬ trza ogranicza sie do minimum potrzebnego do spalania.Obrotowy piec rurowy zaopatrzony jest w mysl wynalazku w szczelnie zamykajace go urzadzenie wyladowcze, które moze byc ewentualnie sztucznie chlodzone, nato-miast powietrze wprowadza sie powyzej tego urzadzenia i w ten sposób, ze ilosc je¬ go moze byc regulowana do minimalnej ilo¬ sci, jaka jest konieczna do spalania paliwa, wprowadzanego równiez w najmniejszej koniecznej ilosci.Piec obrotowy a wchodzi koncem wyla¬ dowczym do komory 6, która sluzy jako komora zamykajaca i do której dolaczone jest schematycznie przedstawione zamknie¬ te urzadzenie wyladowcze c, chlodzone woda lub powietrzem. Woda lub powietrze chlodzace moze byc uzyte pózniej do in¬ nych celów. Powietrze spalania zostaje do¬ prowadzane do pieca obrotowego ponad u- rzadzeniem wyladowczem razem z paliwem rura d, a nastepnie rura e w najmniejszej potrzebnej ilosci. PLRotary tube furnaces for the firing of cement, magnesite, lime and similar materials also have the disadvantage that excess air enters the furnace through the discharge opening, causing the combustion of more coal than is actually required for the firing process. The object of the present invention is to remedy this disadvantage by using a device which is tightly connected to the furnace and allows to regulate the amount of air supplied without or only partially using the heat of the exhaust gases and in the amount needed for the firing process. closed, so even without exploiting the heat of the exhaust gases, the work is more economical, because only a minimum of air is supplied for combustion. The new device can be applied to any rotary kiln, even in those cases where the radiator cannot be turned on due to lack of space. Consideration of these circumstances has led to the conclusion that even if the exhaust heat is partially or completely omitted, a significant saving in fuel can be achieved if the amount of air introduced is kept to the minimum necessary for combustion. The rotary tube furnace is provided in mind. of the invention in a sealing discharge device which may possibly be artificially cooled, while air is introduced above the device and so that the amount of it can be regulated to the minimum amount necessary to burn the fuel fed Also in the smallest quantity necessary. The rotary kiln enters at the end of its discharge chamber 6, which serves as a closing chamber and to which is connected schematically a closed discharge device c, cooled by water or air. The water or cooling air can be used later for other purposes. Combustion air is led to the rotary kiln above the discharge device together with the fuel pipe d, and then pipe e in the smallest quantity needed. PL
