Description
Przy znainych sposobach zapobiegaja¬ cych osadzaniu sie sitalego kaimieinia ko¬ tlowego, oraz nadgryzaniu blach kotlo¬ wych i rur, stosuje sie prad staly niewiel¬ kiego napiecia w ten sposób, ze biegun u- jemny zródla pradu polaczony jest z kor¬ pusem kotla, biegun dodatni natomiast po¬ laczony jest z elektroda, umieszczona albo wewnatrz kotla w wiodzie lub naze- wnatrz kotla w zbiorniku do wody zasila¬ jacej- W pierwszym wypadku osiaga sie zamkniecie obwodu przez wode, w drugim natomiast czesciowo przez przewód zasi¬ laj jacy, W obydwóch wypajdlkajch zuzywa sie elektroda dodatnia, zwykle zrobiona z zelaiza stosownie do przeplywania pradu i nalezy ja odnawiac od czasu do czasu.In the case of known methods to prevent the deposition of the solid boiler lining and the nibbling of boiler plates and pipes, a low voltage constant current is used in such a way that the negative pole of the current source is connected to the boiler body, the positive pole, on the other hand, is connected to the electrode, placed either inside the boiler in the water or outside the boiler in the feed water tank - in the first case it is achieved that the circuit is closed by the water, and in the second case it is partially through the supply line, In both calves, the positive electrode, usually made of iron according to the flow of current, is worn out and should be renewed from time to time.
Nowy sposób polega na tern, ze wo- góle niema zastosowania zasada przeply¬ wu pradu elektrycznego, natomiast kociol lub podobne urzadzenie laczymy tylko z biegunem ujemnym zródla pradu stalego odpowiedniego napiecia, przyczem zródlo pradu stalego jest dobrze odiizolowiatne, aze¬ by zapobiec obiegowi) pradu przez zamknie¬ cie obwodu przez ziemie. W tym wy¬ padku w przeciwienstwie do sposobów znanych niema miejsca, ani zuzycie ener- gji elektrycznej (za wyjatkiem pracy zró¬ dla pradu przy biegu jalowym) ani1 zuzy¬ cie elektrody, wobec czego koszty pracy urzadzenia w mysl wynalazku obnizone sa do stopnia najwyzszego, obsluga przytem jest uproszczona, poniewaz usunietem zo-staje dozorowanie, miarkowanie zródla pradu i odnawianie elektrod.The new method is based on the fact that the principle of the flow of electric current does not apply at all, while the boiler or similar device is connected only to the negative pole of the DC source of the appropriate voltage, because the DC source is well de-insulated to prevent the circulation of the current by closing the circuit through the ground. In this case, in contrast to the known methods, neither the consumption of electric energy (except for idle current operation) nor the consumption of the electrode takes place, so that the operating costs of the device according to the invention are reduced to the highest degree. the maintenance is simplified because the supervision, the measure of the current source and the renewal of the electrodes are removed.
