Major scientific and technological innovation is the State of the weighing, State of the weapon must be firmly in their hands, we must rely on self-reliance and independent innovation. - Xi Jinping December 14, kicked off at the Third International Fair of Innovation and Entrepreneurship Center at the National Convention. As China's first international "double hit" Expo theme show to the world maker culture: power generation, focusing on innovation! Fast Boiler Co., Ltd., Henan Province, to participate as an outstanding representative of the exhibition, at the provincial delegation of the booth, the party fast low nitrogen product model industry vacuum boiler dealer in hue and remote monitoring system is placed at the front, leaders at all levels attach great importance to the domestic foreign passengers .
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.
Henan industry vacuum boiler dealer in hue which method is well known that oxygen oxygen corrosion is a key issue and safe operation of the boiler service life of impact, and with the development of the hot water boiler corrosion problems more prominent, so welcomed by the people of Henan in order to ensure the safe operation of the boiler, oxygen is imperative to take effective measures for the excellent quality of Henan boiler, the boiler Henan oxygen and what method? First, the thermal oxygen Henan boiler heat deaerator, which is the principle of the boiler water is heated to saturation temperature for the corresponding pressure of the oxygen on the water oxygen evolution revisit excluded, so as to ensure the oxygen content of boiler water reaches Henan water quality standards, and Henan boiler thermal oxygen addition methods may not only oxygen, but also to remove carbon dioxide and other gases, users need not worry about this method of oxygen will increase the amount of dissolved salt content and other gases. Second, the vacuum deaerator Henan boiler vacuum deaerator is at less than atmospheric pressure, which also belongs to the low temperature oxygen scavenging. The quality of Henan boiler vacuum oxygen effect, the key is the ability to ensure the vacuum. Will be the same time as the heat load fluctuations, airtight coupled with the entire heating system is difficult to ensure, thus oxygen in the vacuum heating system is not particularly widespread application, the user should pay attention to the selection of such a measure oxygen. Third, the oxygen resolved resolved by strong oxygen binding deoxygenated water and oxygen gas, to achieve the purpose of oxygen Henan boiler, which boiler oxygen Henan method may be performed at room temperature, heating it need not , saves energy, while parsing Henan boiler operating costs than the previous two kinds of oxygen is much lower, but not remove other gases, it also reduces the pH value. Further reliable method of oxygen Henan integrity not only more than several boiler, there is another hydrazine, sodium sulfite and the like oxygen chemicals, resins, and greater investment and oxygen oxygen steel scraps smaller investment, short when the user takes oxygen method for Henan boiler, good to weigh the pros and cons of various methods of oxygen, combined with the economic and budgetary requirements, select the most appropriate, most oxygen methods.
Fast production side vacuum hot water industry vacuum boiler dealer in hue has the following various advantages: 1, good safety performance of boiler. Vacuum hot water boiler operating member remains negative pressure state, even if sudden failure occurs, it will not cause a dangerous situation outwardly explosion. 2, the actual high thermal efficiency. Due to the small heat capacity of the boiler, the heating time is short, low heat losses start-stop; while high-quality insulation materials, heat loss will be reduced to very low, the actual operation of the thermal efficiency is greatly enhanced. 3, long service life. Boiler operation remain closed, heating medium water at the factory once the injection is complete, and is highly processed deoxy, softening, etc., without having to use the latter supplement and does not scale to ensure the long-term normal use of the boiler. 4, a small impact on atmospheric pollution. I produced by using a vacuum hot water boiler premix, advanced combustion technologies of FGR greatly reduced emissions of nitrogen oxides (NOx) and other harmful substances, using a condenser with the flue gas economizer heat fully utilized, only reduce exhaust gas temperature, NOx emissions have also been reduced, very environmentally friendly features.
