fuel fired vertical boiler
Industrial fuel fired vertical boiler water quality testing process in the presence of the presence of water testing boiler problem during industrial Question 1, water scaling problems of industrial boiler during operation, the key indicators are mainly water alkalinity and water hardness. Boiler water alkalinity is scale. Industrial boiler water quality testing process in the presence of water scaling problems for the efficiency of the boiler operation has an important influence. The reason scale problems mainly due during boiler operation, some units and related personnel for the importance of the work of inadequate water treatment, water treatment work thus relatively neglected. At the same time, understanding industrial boilers is also one of the important reasons of scale problems. 2, boiler industrial boiler corrosion problems during operation, that the environment is very bad, there are a lot of alkaline substances and acids. The presence of these substances are boiler would cause adverse effects. Currently, some chemical companies into the production process, the materials that are used in a certain corrosive, which would cause corrosion of the boiler to a large extent, thus affecting the results of its operations. In addition, industrial processes, the agents used, the ratio unreasonable or arbitrary ratio is also an important reason leading to the boiler corrosion. In addition, improper cleaning and protection of the boiler is also an important cause of corrosion problems. 3, water treatment equipment problems With the rapid development of modern industry, water treatment devices have gradually been widely introduced into the market. Currently, in the market, the quality of the water treatment plant equipment is uneven, and thus difficult to play a role in the application. At the same time, water treatment equipment in the application process, some enterprises failed to give due importance to its relationship with water quality requirements, leading to difficult to play effective in actual operation. In addition, when using the water treatment plant, did not do the appropriate acceptance and implementation of the appropriate software is not enough and so on, also contributed to the water treatment plant is difficult to play important pragmatic reasons. 4, boiler maintenance problems in the field of modern industry, industrial boilers industrial production is an important key device, thereby enhancing the maintenance of the boiler also very necessary. However, industrial boilers in actual use, maintenance has been neglected status. This is mainly due to the seasonal nature boiler will exist in the application process, and thus in the maintenance process, should be maintained in accordance with the actual situation. But in the actual work, this work due to human factors and institutional factors and many other factors, it is difficult to smoothly, thereby affecting the operation of the boiler. In summer, for example, due to the presence of water vapor and oxygen gas, which is more prone to water film, not subjected to treatment once bound to increase the corrosion rate of the boiler.
Dry maintenance method should be adopted to stop oil-fired fuel fired vertical boiler for more than one month, wet maintenance method should be adopted for less than one month after shutdown. During the maintenance period should be micro-fire oven, according to the cycle of water, so that the concentration of alkaline solutions are the same. Every five days also take alkaline solution test, such as alkalinity less than 5-12mmol/1 should be added to the solution.
Food factory fuel fired vertical boiler cleaning technology which is currently the main food plant boiler cleaning technology is mainly what? The main existing removal techniques of physical and chemical cleaning descaling, wherein the chemical cleaning was divided: Sin alkali cleaning, descaling pickling, cleaning operation. 1. Physical descaling header mainly taken Xian, flat shovel, wire brushes, hand hammer, water cannons and other artificial mechanical descaling. This method is simple, low cost of labor, poor cleaning, easy to damage the metal surface, mainly used in industrial boiler fouling simpler. 2. The cleaning mechanism base Xian, mainly in certain alkalinity (PH between 10 and 12), which causes the fall off under the action of the drug, and transformed into a scale of good fluidity dirt. To insecticides has trisodium phosphate, disodium hydrogen phosphate, sodium alkyl sulfonate. Sin mainly alkali sulphates for rust and oil-based scale, carbonate scale the effect of bad. Alkaline descaling Xian long time, multi-drug consumption. Such bases typically complex mechanical descaling Sin together, or as a pre-pickling for descaling. Usually put into operation before the new boiler first base Xian boiling out process.
The competition, the segment is slowly 45 contestants only a female welder, most of the other competitors from China Electric Power Construction, veteran welders in the petroleum, petrochemical, and other large number of country prefix units, with a very rich practical operation of work experience. Faced with numerous welding expert, slowly segment did not flinch and fear, but to actively exercise their welding ability, the old master who humbly ask to try a variety of different welding methods, and repeat the training to do practice makes perfect. By her welded fuel fired vertical boiler parts forming the United States, no weld defects neat; in her station, welding clean, neatly stacked tools, work order. It is because of her usual work down to earth, hard work and practice, lay a solid foundation for the success obtained.
