In the boiler supplier 10t latvia production, daily use and installation process must be through welding treatment, then in the boiler welding problem what needs to be paid attention to? Next, we will ask the technicians of Fangkuai Boiler Factory to give us a special introduction: the boiler's furnace tube and boiler's oven box and pipe should be connected by means of welding. Only the boiler tube and the furnace box pipe welding can make it more firm. It is important to note that the heating part of the boiler should be linked by butt welding and bottomed by arc, so as to conform to the overall structure of the boiler. When welding parts of the boiler's edges and corners, it should be maintained. The roundness of the welding joint can not appear some small defects, otherwise, these are very easy to cause the operation failure and safety hidden trouble in the process of use.
Fast boiler supplier 10t latvia in gas boiler industry has been at the leading level for low nitrogen environmental aspects of deep research. Dingzhou Yili Dairy determined after reaching cooperation with our company, launched a work plan for the boiler low-nitrogen transformation. Yili Dairy Dingzhou three original boiler 15t / h gas steam boiler, NOx emissions have reached 150mg / Nm3, belonging to the boiler equipment far exceeded. After the party fast professional and technical engineers, boiler and boiler model parameters to fully understand the components, rapidly developed a specific rehabilitation programs, start from the combustion system to achieve NOx emissions of 30mg / Nm3 to meet the most stringent environmental standards of the atmosphere.
In such an ever-changing era, it is an opportunity and a challenge for enterprises. Many of the former big companies were left ruthlessly by time because they could not keep up with the times. ZG boiler has been in existence for more than 70 years and is moving towards becoming a century-old company that is most trusted by customers in the boiler industry. In the past 70 years, ZG boiler has been advancing more and more, and it has become increasingly powerful under the polishing of time.
In production, there are often some thorny problems in boiler supplier 10t latvia operation. Needless to say, the editor for you to sort out the boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. In the process of manufacture, transportation, installation and maintenance of boiler, it is inevitable that some impurities such as dirt, iron chips, welding slag, iron oxide and so on will be produced and glued to the pressure parts of the steam and water system in the process of manufacture, transportation, installation and maintenance. As soon as these impurities enter the steam-water system in operation, they will do great harm to the boilers and steam turbines. Therefore, the boilers before they are installed and overhauled must be chemically cleaned to remove them. Feed-in speed of boiler before start-up Degrees should not be too fast, generally no less than 4 hours in winter, other seasons 2 to 3 hours, especially in the initial stage of water should be slow. The inlet water temperature of a cold boiler is generally at 50 ℃ 90 ℃, so that the difference between the feed water temperature entering the drum and the wall temperature of the drum is less than 40 ℃. If the boiler is not fully cooled, the inlet water temperature can be compared with the drum wall temperature, otherwise, the inlet water speed should be slowed down. The reason is! (1) because the drum wall is thicker and the expansion is slow, the tube wall connected to the drum wall is thinner and the expansion is faster. If the inlet temperature is too high or the inlet speed is too fast, it will cause unevenness of expansion, crack of welding joint and damage of equipment. (2) when water supply enters When the drum is in contact with the lower wall of the drum, if the difference between the feed temperature and the wall temperature of the drum is too large, the speed of entering the water is fast, the upper and lower walls of the drum, the inner and outer walls of the drum will produce a larger expansion difference, resulting in a larger additional stress to the drum. Causes the steam drum to deform, produces the crack when serious. When the temperature of the heated surface is lower than the dew point of the flue gas, when the temperature of the heating surface is lower than the dew point of the flue gas, the steam in the flue gas is combined with the SO2,SO2 to form the sulphuric acid steam, which condenses on the heated surface. The boiler always causes low temperature corrosion of the heating surface first. The cold end of air preheater is prone to low temperature corrosion.
