(A), the necessity of cleaning the boiler after a long-running water boiler detergents, the inevitable emergence of scale, corrosion problems slag remover, boiler scale formation is mainly due to the hardness of the water with the ingredients, after temperature, concentrated by evaporation after the continuous pressure, occurs in the furnace a series of physical, chemical reactions, culminating in the heating surface to form a hard, dense scale. Scale is "harm the song" boiler, the boiler is the main cause of accidents, the danger is mainly manifested in: waste a lot of fuel: Because the thermal conductivity of the scale of only a few tenths of detergents steel, so when the heating surface After fouling causes heat blocked, in order to maintain a certain boiler output, it is necessary to raise the temperature of the fire-side, so that the external radiation and exhaust heat loss. Due to different working pressure of the boiler, the type and thickness of different scale, different amount of fuel wasted, for the hot plate test and calculation based on detergents, scale thickness and loss of fuel has the following proportions: When the scale thickness (S) ≥ When 1mm, waste fuel from 5 to 13%; when ≥2mm, waste of fuel 13 to 18%; when ≥3mm, 18 to 26% waste fuel. (Two), easy to make steel pipe was burning due to overheating because the boiler fouling, but also to maintain a certain amount of work pressure and evaporation, only to raise the temperature of the fire side, but the thicker the scale, the lower the thermal conductivity, thermal have higher temperature side. Generally boiler fire-side temperature of about 900 ℃, and the temperature of the water side at about 190 ℃. The temperature of the steel plate at about 230 ℃, once fouling around 1mm, when the temperature of the steel plate than Paradise increased about 140 ℃ when there is no scale. 20 # steel when the temperature reaches 315 ℃, the plasticity index of metal began to decline when it reaches 450 ℃, metal creep deformation due to overheating. So boiler fouling is very easy to make the metal is burning. (Three), increasing maintenance costs and reduce the life of the main component is a weak acid descaling the kettle. Want kettle descaling actually have a pretty good method is to use white vinegar to soak, good results, and safe. Our company is the exclusive introduction of the Ministry of Chemical Machinery Institute research new products, the State Science and Technology Commission recognized national new products, has been included in the national focus on promoting scientific and technological achievements. This product can quickly and completely remove the scale attached to the inner wall of the boiler is suitable for all kinds of boilers, electric boilers, main ingredients include food acids, penetrating, accelerators, metal materials protective agent. 1, chemical cleaning process: water erosion → acid cleaning → water washing → passivation treatment; 2, disconnect the boiler other system-independent, tank cleaning, clean the pump with a clean boiler connected into a closed loop; 3, By imitating a clean state to leak check the status of the cleaning system, along with the boiler remove loose dirt, when erosion at the outlet of the water when there is no visual presence of large particles of impurities, water erosion is completed; 4, after the completion of water erosion, clean the tank increase circulation boiler cleaning agents ", the main control agent concentration in the cleaning 3-6%, temperature in the range of 50-60 ℃, the inner loop in the system were clean decontamination, cleaning time 2-3 hours or so. punctuality with pH paper measure the acid pH (1/20 minutes), to keep them in a less stable when the pH value within half an hour without a clean gas release system, the completion of the pickling process; available detergents _ _ detergents Dongguan Ferrer Ferrer trade provided by the Dongguan City Trading Co., Ltd. of Dongguan City Ferrer (www.furui-china.com) strong, credible, industry in Dongguan, Guangdong with a cleaning agent industry has accumulated a large number of loyal customers. The company better work attitude and constantly improve the innovative ideas will lead Dongguan Ferrer trade and you hand into the brilliant, for a better future!
