Effect of sodium vanadium complex on the protective layer of metal oxide film
The drawback of raising the temperature of exhaust gases is increased heat loss and a decrease in overall thermal efficiency. However, for industrial enterprises with less-than-ideal furnace combustion conditions, increasing exhaust gas temperature can serve as a temporary measure to delay low-temperature corrosion. Additionally, for areas where the metal wall temperature is close to or below the acid dew point, two additional strategies can be implemented: adding insulation to flues or chimneys. This helps reduce heat loss from the flue gas and ensures that the flue gas temperature remains above the acid dew point, thus minimizing the risk of corrosion.
Another approach to reducing low-temperature corrosion involves lowering the water vapor content in the flue gas. An increase in water vapor enhances the severity of low-temperature corrosion in two main ways. First, at a given temperature and in the presence of sulfur trioxide, more water vapor leads to the formation of more sulfuric acid vapor. Second, higher water content raises the dew point of the gas, increasing the likelihood of condensation and the production of liquid sulfuric acid. This is especially important when using water vapor atomization, as the amount of atomized water must be carefully controlled to meet combustion requirements without excessive moisture buildup.
Cleaning ash deposits also plays a significant role in mitigating low-temperature corrosion. The accumulation of ash on metal surfaces can react chemically with sulfuric acid, forming a "cement-like" white sludge that contains compounds of vanadium, sodium, and sulfur. It is believed that the continuous interaction of sodium-vanadium complexes with the protective oxide layer on the metal surface accelerates corrosion. Moreover, this sludge can absorb more particulate matter, leading to a cycle of buildup and adhesion that worsens corrosion on the metal walls. Therefore, it's essential to regularly remove these deposits to prevent further damage and maintain the integrity of the system.
Camping light is a portable lighting device designed for outdoor activities, especially for camping, hiking, picnicking and other outdoor activities. The main features of camping lights include lightweight, waterproof, durable and a variety of lighting modes to meet the needs of different scenes. They typically feature LED technology to provide efficient, energy efficient lighting, and many modern camping lights also feature solar charging, making it easier to use outdoors.
Camping lights are designed to take into account the diversity of outdoor environments, and many products are waterproof and fall-resistant, capable of stable operation in adverse weather conditions. In addition, the portability of camping lights is also an important factor, many camping lights are designed to be easy to carry and can be used by portable, hanging in the tent or fixed to a tripod.
In terms of function, camping lights not only provide basic lighting functions, but also may have SOS signal function, multi-level brightness adjustment and charging bank function, so that it can play a role in emergency situations. Some high-end camping lights also use intelligent control technology, which can be remotely controlled through mobile phone apps to provide a more convenient experience.
In general, camping lights are one of the indispensable equipment in outdoor activities, which can not only provide the necessary lighting, but also play a role in emergency situations to ensure the safety and comfort of outdoor activities. With the advancement of technology, modern camping lights are not just simple lighting tools, but outdoor companions that integrate a variety of practical functions.
