How to deal with scientific boiler water? First, at this stage, there is the problem of boiler water treatment boiler water treatment 1. The lack of attention to work industrial boilers can not do without, but there are a lot of staff do not pay attention to boiler water treatment, and also from time to time to carry out boiler water treatment. The main reason for this phenomenon is that the enterprise management and staff did not recognize the dangers of not treating boiler water, over time, will produce boiler scaling, corrosion and other problems. 2. A boiler water treatment method is not correct in the actual production, the boiler is used to contain various liquids. But some staff do not know that for different kinds of liquids what action should be taken. In addition, some companies use a simple boiler water treatment equipment. These factors can pose a security risk to the boiler, resulting in security incidents. 3. Staff overall quality is not high and some staff members did not follow the rules and regulations of the boiler water for testing. In addition, some of the work of professional quality is not high, so that work is not high efficiency boiler water treatment, resulting in the deviation of the test results. There are even some staff members will laboratory data on fraud to fool the upper management.

How to deal with a hot water heating system, a hot water heating system dirt long run, the system will gather a lot of dirt and water stains, if not addressed, will affect the operating results and boiler heating effect. How to deal with these stains and scale? 1, the water is softened salt water against calcium and magnesium scale these major induced species, the effective use of long soft water treatment method, i.e. sodium ions to soften. This caused the water in the boiler will scale method to dispose of the material and not into the circulatory system is and should be in the affirmative. If the raw water is injected and the whole heating system are replenishment of demineralized water, then the residue under high hardness standard soften water, water will not fully described actuation handle clean dirt substances, also in the raw water and softened water replenishment systems are state will produce a certain amount of water residue. Thereby associate the water treatment device to the magnetic field in recent years, which is manufactured in accordance with the water after a certain strength of the magnetic field into the boiler, causing crystallization of salt water scale is changed such that the new scale not generated, prompting the old dirt shedding It becomes sludge. I would like to note that, even when used in combination, the residual hardness of the water because the system will generate a certain amount of water residue. 2, decontamination decontamination disposed in the boiler room and the indoor inlet duct system, so as to effectively separate the water residue. But practice shows that separation effect is limited. In particular inlet disposed in the boiler room decontamination, it can be said that almost no separation. Regardless of which design is a vertical or horizontal filter and is used in larger volume to achieve the purpose of precipitating impurities separated from the water. Can imagine, however, the speed of water flow in the pipe nearly 2 meters / second metal filter unbearable flow impact force, coupled with the effects of corrosion life of the filter is difficult to maintain more than one month. And the volume of decontamination of how limited it can produce precipitation. Cyclone decontamination emerged in recent years is also problematic, this method often used in the separation of the gas particles. Water is different, the proportion of slag sand and clay in the composition with water in a large difference is only large particles, fine particles can not be separated, so decontamination cyclone separation effect is limited. So I did not have a good practice of separating the role of decontamination do? Yes, a large volume of decontamination tanks can play a good role separation. 3, in the boiler blowdown general instruction of steam boilers blowdown is very important, and the effect is very clear, whether periodic or continuous blowdown discharge can effectively expel excess boiler water salinity. But in hot water boiler blowdown effect is not very obvious. The difference is that: first steam boiler feed water per hour only 10T, while the hot water boiler with capacity for 240T. It can be seen in the water flow of the hot water boiler is particularly large, as compared with more than 20 times the capacity of a steam boiler. The most commonly used method is to discharge, the circulation pump outage for 2 hours and then precipitated impurities in the water to be seen until the water drain valve is opened. However, this method has limited effect discharge, and the drum is provided as outfall lower header tank can not be drained away precipitate. 4, for cleaning stains proved that treatment by chemical and mechanical methods of combining the most effective cleaning slag. Some people think that after you configure a valid demineralized water facilities in the heating system and no more effort to clean. This concept is not realistic, it should be said, that there must be softened water treatment, but also combined with the cleaning method is the most effective and thorough approach. (1) inside the boiler cleaning winter operation after opening the boiler we can see a lot of red fluffy black slag deposited on the bottom of the drum and the collection box, also seen in the sheet-like water residue adhered drum, a water-cooled wall, the inner wall of the smoke pipe and collection tank. The water wash residue can be chemically or mechanically. Conventional mechanical means is prepurge; a better cleaning effect, but the pot is limited space, especially for pyrotechnic impossible to use the boiler tubes. Methods of chemical cleaning with high pressure water boiling out mechanical grab combination is effective, to the extent that can meet heating surface qualities of the composition. (2) After cleaning the winter run outside the network and indoor facilities outside the network and indoor facilities in the slag should also be cleaned, clean room facilities often simple people start cleaning, extranet cleaning slag recycling can be used under the functioning of the pump system in the room to deal with the sewage entrance decontamination method.
Proper Cleaning of Steam Boiler. One of the oldest ways is to dissolve a pound of tri-sodium phosphate (TSP) and a pound of caustic soda (lye) in water and pour it into the boiler.
