gas vertical steam heating boiler

Note the choice of industrial vertical steam heating boilers from the first industrial revolution to develop microbial technology, and upgrading various products continue to emerge, led us to the development of human civilization from the original backward to technological civilization, to the boiler, for example, since the last century, there has been a cylinder since the boiler-shaped, with the needs of science and technology and production, from simple to complex, from single to serialization, boiler technology are developing rapidly, the good reputation of industrial boilers companies choose to share precautions industrial boilers; first, the coal use; the design of the cell structure based on coal boiler components as the design basis, select the boiler should pay attention to adjust to the type of coal in the region. It recommended new, high-efficiency, high-tech, high-quality, durable industrial boilers; second, parameter selection; industrial efficiency boiler work normally when approaching the highest efficiency rating, as the load decreases efficiency has declined. Boiler capacity is generally selected: it generates a large steam than the actual gas consumption, such as the required parameters and actual parameters difficult to match industrial boilers, high boilers in this case a gear selection parameter. Selection of auxiliary boiler should also refer to the above principles, to avoid the "big horse car"; third, the number of choices; normal maintenance of industrial boilers and boiler shutdown is a number of factors, but also pay attention to: the boiler room shall not exceed the number of boiler economizers work load, install boiler economizer device purpose is to avoid too much heat when the smoke away. Improve the thermal efficiency of the boiler, is provided in the back pass boiler economizer heating surfaces, the use of flue gas heating boiler feed water, to save energy, economizer after the installation, the boiler increases the thermal energy required for heating the feedwater, boiler water and so reducing the temperature difference between the water supply, reduce the burden of heating boiler feed water. Cause excessive number of boiler economizer can not play a role, resulting in waste of energy; These are high-quality industrial boiler company to share some notes selected industrial boilers; vast land of our country, many places are rich in coal, resulting in different types of coal , which has also become a basis for selection of parameters and select the number of boilers enable us to be more effective in energy conservation, to achieve a win-win.

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 vertical steam heating 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.

6 tons of chemical technology chemical parameters of natural gas steam vertical steam heating boilers 6 tons of natural gas steam boiler technical parameters? Nowadays, people's food, clothing and housing are inseparable from the so-called chemical products. Chemical and chemical industry can be referred to as chemical, petroleum, pharmaceuticals, agriculture and so a place in the chemical industry. As chemical products processing, and various chemical plants, although there will be differences in the production process, but they can not leave some processing all the necessary equipment, steam boilers and other production. 6 tons WNS gas steam boiler, chemical production fast boiler dedicated premix combustion boiler technology, wings tubes, of FGR other new technology to increase the thermal efficiency of the boiler. Manufacturers increase production capacity. 6 tons of gas steam boiler technical parameters are as follows: Model Rated evaporation (6t / h) rated steam pressure (1.6.MPa) WNS6-1.6Y (Q) of natural gas, light oil and heavy oil fast filling. Of course, six tons of gas steam boiler is representative of WNS boiler, three times the structure, energy-efficient gas boiler. Six tons of steam boiler is mainly used in small-scale production and use is very diverse. Class 6 t good gas-fired boiler structure, take up less space, and a low one-time investment, high thermal efficiency.

In the national standard of water quality standard, the water quality index of hot water vertical steam heating boiler stipulates that the total hardness of water supply for chemical treatment outside furnace is less than 0.6 mmol / L. In recent years, in order to reduce the operating cost of heating units, some hot water gas-fired steam boilers have been overloaded due to the use of class Ⅲ bituminous coal as fuel instead of class Ⅱ bituminous coal designed to replace the designed type Ⅱ bituminous coal. During the maintenance in summer, it is found that the overloading boiler water wall tube fouling problem is more prominent, some boilers even occur tube burst accident. Why is heating hot water boiler overloaded, scale and even burst tube? Because the calorific value of class Ⅲ bituminous coal is higher, the type Ⅲ bituminous coal of the same weight is burned instead of the designed class Ⅱ bituminous coal. Bituminous coal increases the circulation of boiler riser is not absolute equilibrium, the geometric difference of riser and the heat load are different, so there is inevitably the deviation of flow rate between the risers. Due to the overloading operation of the boiler, some riser tubes are easy to overheat boiling because the flow rate is small, and the wall temperature is higher than the designed wall temperature, so that the scale and even the tube burst are easy to occur. How to prevent the boiler from scaling when overloaded? The heating hot water boiler operates under overload because of the scaling after the superheated boiling. Steam is produced in the process of superheated boiling. The water quality requirement of gas steam boiler is less than 0.03 mmol / L, which is much lower than that of hot water boiler. Water quality requirements. Based on the above reasons, the feed water hardness of heating hot water boiler is reduced, and the scaling phenomenon is eliminated by reducing 0.6mmol/L to 0.03mmol/L.
