Gas boiler Selection Method: Compared to coal-fired boilers, gas boilers with a cleaner, more environmentally friendly, energy efficient properties. Has been applied to the food, chemical, pharmaceutical, paper, printing and dyeing and other industrial production, it can also be used in terms of hotels, hospitals, schools, military units, residential district heating and sanitary hot water. But many users there is a demand for the selection of a gas boiler still confused, fast Boiler summed up the points the following method, for your reference.
Low temperature hot water boiler economizer regular cleaning to water causes and explanation: A boiler for hot water boiler which, I believe we will not feel it is strange, but should also have a certain degree of knowledge and understanding, because the site He has been engaged in the study of their work. And here, will continue, so that we become more familiar with hot water boiler, at the same time, can also complement and expand their expertise in this area, so a lot of their own benefit. 1. The low temperature hot water boiler economizer, why should be cleaned on a regular basis? This is because the low-temperature hot water boiler economizer this means that after a long time use, the efficiency of heat transfer to the heat receiving surface, due to various factors, would decline, then, will increase boiler fan output, as well as increased power consumption. In addition, there may, and will bring some security risks and other risks. Therefore, to be cleaned regularly to avoid these problems, so as to ensure the efficiency of hot water boilers. 2. pressure hot water boiler, which valves should it use? And, the need for the user's own option? Pressure hot water boiler, a valve that should be used, in general, most are disposable valve instrument, because it is more appropriate, but can also have a good effect. These valves, usually without the user's own option, when the boiler factory, the factory will be configured.
Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
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 1000kw h diesel steam boiler for price 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.Free Chat
