Horizontal Gas Vacuum Hot Water Boiler

What problems on the steam boiler is very important but not involved? Steam boiler, the following, mainly through a number of specific issues, to learn their work, and give their corresponding answers, so that we have to learn the content, and then, on the products, some gains and progress, at the same time, You can also promote the learning process of the product. 1. steam boiler, which is widely applied in what industry? Its specific use, which are more? Steam boiler in the boiler, in general, that in the paper, printing and dyeing, as well as chemicals and other such industries, there is a wide range of applications. Which in particular uses, it is used in the drying more, to supply hot air or the like, and further, to smooth the drying operation. 2. A boiler steam boiler which, whether they have prescribed period of use? In addition, it is part of the special equipment it? Steam boilers this kind of boiler, which is not specified period of use, though, that there be scrapped, if it reaches the thermal efficiency than required, or can not ensure the safe use, then, is to be scrapped deal. However, this kind of boiler, its reasonable and properly used under normal circumstances, it can be used for about 10-15 years. Steam boilers, whether they are special equipment, will depend on the actual situation, if it is a high pressure, then for special equipment; if it is a vacuum type, then, does not belong to special equipment.

How to guarantee steam quality of steam boiler

Steam boilers are much more widely used than hot water boilers. Hot water boilers are mainly used for heating and providing hot water supply, while steam boilers cover all industries such as industrial and power generation. What are the requirements for boiler boilers for boiler boilers? Undoubtedly safe, stable, efficient, long service life, cost savings, etc., however, these requirements are indirectly or directly related to steam quality. The quality of steam is critical because it affects the stability, reliability and economy of the system, as well as product quality, production power and energy consumption. If the steam boiler user does not pay attention to this, it will definitely lead to a series of follow-up problems for the boiler.

1) Cleanliness: There are rust and carbonate deposits in the steam pipeline, and there may be slag and sealant fragments remaining in the equipment. These impurities may cause jamming and damage to the valves and equipment, and also increase the wear of the pipeline. The way to improve cleanliness is to install a pipe filter, and the filter should be horizontal.

2) Dryness: Incorrect water treatment of boiler hydration, unreasonable boiler level control, and short-term high peak load and other factors will cause the boiler to co-exit the boiler, so that the boiler outlet carries boiler water. When steam is moving in the pipeline, heat dissipation from the pipeline condenses a portion of the steam, adding condensate from the pipeline. The chemical substances and other impurities carried in the condensed water will accumulate on the surface of the heat exchange equipment, affecting the power of the heat exchange equipment, and the accumulated impurities will be fouled on the metal surface of the equipment, resulting in uneven heating of the metal surface and shortened life. In addition, the presence of moisture in the vapor reduces the transpiration of the steam, adding steam consumption; the moisture in the steam will increase the thickness of the water film measured by the heat of the heat transfer, and the rated heat transfer resistance occurs. The addition of a steam separator is a useful way to improve steam dryness, and an efficient steam separator can increase steam dryness to 98%.

3) Purity: There is air in the steam system because the steam that is generated by the boiler still inevitably contains a small amount of air, and there are also air when the pipes and equipment are started. When the system and equipment are shut down, the air is taken in due to the internal vacuum. The air has a very low thermal conductivity and is a poor conductor for heating. The inclusion of air in the steam system will reduce the production capacity of the steam equipment and will also increase the corrosion of pipes, valves and equipment. The most useful way to eliminate non-condensable gases such as air in a steam system and thereby improve the purity of the steam is to install an automatic air venting device in the system.

4) Pressure/temperature stability: In order to ensure process heating requirements, the steam pressure at the steam point should reach the demand value. Together, the steam pressure should not be too high, otherwise steam consumption will be added.

What are the advantages of vacuum boilers?

Because the inside of the furnace is a vacuum, the heat medium condenses onto the heat exchanger after it is heated and evaporated, so the heating medium is no more than the heating medium in the process of use. At the same time, it is more energy-saving and environmental-friendly than other types of boilers. Do you know what are the main advantages of the most reliable vacuum boiler? Here is a brief introduction to the advantages of vacuum boilers.

1, high efficiency and energy saving because the vacuum negative pressure hot water technology is used in the production design of the vacuum boiler, so it can make the boiler run in the vacuum state, and its boiling point is low, and it can carry on the latent heat exchange of vaporization (condensation latent heat). And using the three-way wet back design, the heat transfer performance is good and can effectively improve the radiation and convection heat transfer area, so it is more efficient and energy-saving.

2, multi-purpose because vacuum boilers are not only divided into vertical, horizontal, fuel and gas and many other models that are freely available to the user, but also because its heat exchanger and header are a separate state. Therefore, the load of heating water and hot water can be switched at any time according to the actual needs, which can fully meet the different requirements of users for heating water and clean hot water, and ensure that hot water is clean and stable so as to realize multi-use of one machine.

3, the installation is simple because the vacuum boiler is manufactured with modular design and high-performance heat transfer components, so the unit size of the boiler is smaller. It is not only convenient for transportation and storage, but also simpler and more convenient in installation method. In addition, it can also be conveniently installed in a small space or can be used in parallel operation of multiple units according to the actual needs. These three parts are the main advantages of vacuum boilers.

Fangkuai Group has more than 60 independent intellectual property rights, advanced clean fuel boiler manufacturing technology, and jointly established a clean fuel boiler production, research and research cooperation base with Tsinghua University and Xi'an Jiaotong University. An enterprise with a R & D and test center for clean fuel boilers. The thermal efficiency of “Fangkuai” boilers can reach 107%, which has been included in the national special equipment energy-saving catalog. The company developed ultra-low nitrogen full premixed combustion condensing boilers and ultra low nitrogen emission fuel gas boilers, which are developed by the company using Ultran condensation technology.
