heating surfaces of water tube boilers

Installation qualification a range of heating surfaces of water tube boilers installation and boiler soda processes: boiler manufacturing factory site in the box, there are different types of boilers and boiler products, however, we want to have a comprehensive knowledge and understanding of these boiler products, then, not only to learn more about these types of boilers, in addition, on the whole boiler, it should also be in-depth, so the job. So below, from the whole boiler, to carry out work related learning, so that we all get something from the new knowledge. 1. Install the boiler installation qualification Qualification boiler, Is there a limit on the scope of the boiler installation? A boiler installation qualification boiler installation qualification, which is mounted in the area of ​​the boiler, the boiler according to the manufacturer block describes the production, there is no limit, i.e., may be all kinds of boiler installation. And, at this point, we should have a correct understanding, you can not go wrong. 2. The temperature of the heating boiler, whether the size of the furnace? Its return water temperature, is generally much? Heating temperature of the boiler, from a professional point of view, is the size of the furnace, and a great relationship between the two. However, in general, the heating temperature of the boiler, is in this range 90-110 degrees. The return temperature of the boiler, boiler manufacturers produce a block that is generally 50 to 70 degrees.

We all know that the heating surfaces of water tube boilers and have a large, dangerous equipment, so the transformation process we need to pay attention to some problems to be able to make it to transform all aspects of security smoothly, here to explain to the transformation of content that need attention. 1, note that prior to the step of performing the transformation of the boiler torn down to be demolished for main and auxiliary engines; but how demolition, require the operator to advance the development of a detailed demolition plan based on the boiler situation, and then based on the removal step, step by step removal, not indiscriminate demolition, or is likely to cause accidents. 2, pay attention to the transformation of the transformation of the boiler furnace, many steps are focused around the hearth to transform the general professional boiler when the company will be re-engineered to the furnace pouring new furnace, replacing the old hearth; Also note that, after the original boiler burning arch tube can not have been affected by high temperatures, leaving the center point of the flame, this will allow the furnace to become more durable. 3, do not forget to test a lot of people working in the boiler after the completion of renovation work will feel all is well, it is not true, but also to perform a comprehensive test work after the transformation of boilers, for boiler pressure test to be 1.5 times the rated pressure. If the test results are normal, you can complete deliveries.

What kind of industrial heating surfaces of water tube boilerss are worth paying users not only is a large agricultural country, is also a major industrial country, which created a vast industrial boilers development stage. Not only give chemical plants, pharmaceutical plants, chemical plants, cement plants, steel mills to provide energy, but also give food processing, medical, petrochemical and other industries conveying high temperature steam, we can see, for the production of industrial enterprises, industrial boilers are very an important class of device. So, what kind of industrial boilers is worth our choice? 1, good safety performance good safety performance is the basis for normal and stable operation of the industrial boilers. Just boiler explosion occurred this year has been more than 10 cases, economic and personal security have caused serious and irreversible adverse effects. Boiler itself belongs to special equipment, the internal pressure, once the abnormal fault occurs, the consequences could be disastrous. Thus, the security should be placed in the primacy of factory production, then you need to pick the trusted manufacturer of industrial boilers center, safety is guaranteed. 2, energy saving and environmental protection to people still living a healthy environment, China's environmental protection department for emissions of air pollutants requirements become more stringent, exhaust gas emissions for the plant to investigate the phenomenon is particularly strict. Once the environmental protection department to check out the factory boiler exhaust failure, it will be immediately asked boiler outage, when faced with plant-wide shutdown to change the rule of the storm. The professional industrial boiler manufacturers adopt advanced low nitrogen processing technology to optimize boiler emissions, making it reach the national energy saving industry standards. 3, after-sale protection of industrial boilers event of a failure, hot water or steam supply systems will appear immediately interrupted, causing factory can not continue to produce. If glitches occur, then the plant maintenance division to complete the overhaul, but if it is a large fault required to notify the manufacturer of the boiler; service becomes very important, and only after-sale protection boiler manufacturers to make the boiler to the maximum extent It has been running smoothly. On the whole the price is also very cost-effective. Thus, those industrial boiler safety, environmental protection, after-sale protection worthy of our choice. Although not directly bring industrial boiler plant efficiency, but a good quality boiler but can indirectly benefit to the plant. In the selection of the boiler, can be considered to start from three points above analysis, I believe we can get the satisfaction of industrial boilers.

Fang fast, based on the heating surfaces of water tube boilers industry, the rise in clean-burning, low-nitrogen management in a more environmentally friendly. In the family group when Mr. Lu Haiqing's correct leadership, we deepen the industrial revolution, brought together the group cohesion, pioneered premix, FGR low nitrogen and other advanced processing technology and products in the industry; more than 100 national patents so that we in the industry chasing; unique cloud service remote control system for boiler intelligent control. Anyang City, the first batch of standards implementation of intellectual property rights demonstration units, the industry's first high-tech digital exhibition hall, China's first put into practical operation of the low nitrogen boiler ...... party fast data demonstrate, to speak with strength.

So the designers can no longer ignore the process of circulation of water and steam in the boilers. Inadequate circulation of water would fail to remove heat from the tube surface at a sufficient rate, which may lead to increased tube wall temperature. The allowable stress of the metal reduces with increasing metal temperature. In an extreme case the tube may rupture.
