Description

Wynalazek dotyczy urzadzenia do wy¬ muszania przyspieszonego i odpowiednio skierowanego krazenia wody w kotlach pa¬ rowych dowolnej konstrukcji.Dotychczas próbowano opanowac kra¬ zenia wody w kotlach parowych przez od¬ powiedni uklad rur wznosnych i rur opa¬ dowych, oraz zbiorników dolnych i gór¬ nych, przyezem rury wznosne i opadowe ze¬ stawiano nieraz injektorowo. Jednakowoz doswiadczenia wykazaly, ze w ten sposób nie mozna osiagnac pozadanego wyniku, zwlaszcza, gdy istnieja wahania w odbio¬ rze pary i natezenia w opalaniu.Niniejszy wynalazek rozwiazuje ten problem w ten sposób, ze zasalanie rur wznosnych ciecza odbywa sie za posred¬ nictwem urzadzen zaworowych, które nie- dopuszczaja do niepozadanego cofania sie cieczy, gdyz urzadzenia te zamykaja sie w takich wypadkach mniej lub wiecej, albo tez przeciwstawiaja wstecznemu pradowiwody mniejszy lub wiekszy opór. Przez u- rzadzenia zaworowe nalezy rozumiec za¬ wory lub klapy zaporowe.Zawory te moga byc umieszczone w do¬ wolnej czesci rur wznosnych lub opado¬ wych, wzglednie w dowolnem miejscu w stosunku do walczaka kotla.Zalaczone rysunki uwidaczniaja istote wynalazku.Fig, 1 uwidacznia kociol Mass'a, posia¬ dajacy 10 rur wznosnych a, zasilanych z rury opadowej 6, za posrednictwem zawo¬ ru wstecznego d.Po lewej stronie fig, 1 znajduje sie za¬ wór wsteczny na dolnym koncu rury opa¬ dowej 6, a po prawej stronie fig, 1 taki za¬ wór znajduje sie na górnym koncu drugiej rury opadowej 6.Mieszanine parowo-wodna mozna wpro¬ wadzic rura e wprost do przestrzeni paro¬ wej górnego kotla / tak, ze ciecz moze przejsc z górnego kotla do rur wznosnych tylko przez rury opadowe 6.Fig. 2 przedstawia kociol wodno-rar- kowy dowolnego typu, zaopatrzony w rury wznosne a oraz w rury opadowe 6. Zawo¬ ry wsteczne d znajduja sie tu np, w dol¬ nym kotle g. Takzei tu mozna rury wzno¬ sne a wprowadzic ewentualnie wprost do przestrzeni parowej górnego kotla /.Szybkosc krazenia wody wzrasta bardzo znacznie, gdyz woda nie moze sie coifac, a mniej lub wiecej zupelne zamykanie sie, np, zaworu wstecznego, powoduje wzrost cisnienia i przyspieszone opróznianie sie rur wznosnych.Wynalazek moze miec równiez zastoso¬ wanie gdy niema dolnego walczaka, tak ze rury wodne ida od górnego kotla do pale¬ niska i wracaja znowu do walczaka, przy- czem zawór wsteczny moze sie znajdowac w dowolnem miejscu a rury te moga posia¬ dac srednice rozmaite. PLThe invention relates to a device for imposing an accelerated and properly directed circulation of water in steam boilers of any construction. Until now, attempts have been made to master the circulation of water in steam boilers through the appropriate arrangement of riser pipes and downpipes, and of lower and upper tanks. At the same time, the riser and downfall pipes were often set up by injectors. However, experience has shown that it is not possible to achieve the desired result in this way, especially when there are fluctuations in the vapor reception and the firing intensity. The present invention solves this problem in that the plating of the liquid riser pipes is carried out by means of devices. valves, which prevent undesirable backflow of liquids, because these devices close more or less in such cases, or oppose the reverse current to the water by a greater or lesser resistance. By valve devices is to be understood stop valves or dampers. These valves can be placed anywhere on the riser or downpipes or anywhere in relation to the boiler drum. The attached drawings show the essence of the invention. shows a Mass boiler having 10 risers a fed from a downpipe 6 via a backflow valve d. On the left side of FIG. 1 is a backflow valve at the lower end of the downpipe 6, and on the right side of Fig. 1 such a valve is located on the upper end of the second downpipe 6. The steam-water mixture can be introduced directly into the steam space of the upper boiler / so that the liquid can pass from the upper boiler to the pipes risers only through downpipes 6.Fig. 2 shows a water-boiler of any type, provided with riser pipes a and with downpipes 6. The back valves d are located here, for example, in the lower boiler g. Here too, riser pipes can be inserted directly to the steam space of the upper boiler /. The speed of water circulation increases very significantly, because the water cannot flow, and more or less complete closing of, for example, the back valve, causes an increase in pressure and accelerated emptying of the riser pipes. The invention can also be applied to It is precisely when there is no lower drum so that the water pipes go from the upper boiler to the burner and return to the drum again, whereby the back-valve may be anywhere, and these pipes may have various diameters.
