effect

Economizer, as the core component of power plant boiler, plays an important role. Its main function is to recover and utilize the waste heat in the flue gas, which preheats the feed water entering the boiler. In this way, the exhaust gas temperature can be reduced, thereby improving the overall operating efficiency of the boiler.

During the operation of the boiler, the flue gas takes away a large amount of heat energy. If this heat energy cannot be effectively utilized, it will cause a waste of energy and reduce the efficiency of the boiler. Economizers are designed to solve this problem. Through its special structure and material, it causes heat exchange between the flue gas and the feed water, which increases the temperature of the feed water, thereby lowering the exhaust smoke temperature.

There are many factors that need to be considered in the design and operation of an economizer. First of all, its material must be able to withstand the test of high temperature and highly corrosive environments to ensure long-term stable operation. Secondly, its structure must be reasonable so that flue gas and feed water can be fully mixed and heat exchanged. In addition, the maintenance and cleaning of the economizer is also very important, which helps ensure its efficiency and longevity.

working principle

The economizer is usually installed in the tail flue of the boiler. This unique design makes it an integral part of the boiler system. The main function of the economizer is to use the heat of high-temperature flue gas to heat the feed water and gradually increase its temperature, thereby realizing the recovery and utilization of heat energy.

During the operation of the boiler, high-temperature flue gas generated by fuel combustion will be discharged through the flue. The economizer is installed at the end of this flue. When the high-temperature flue gas passes through the economizer, it will heat the water molecules inside it, causing the temperature of the feed water to rise. This process fully embodies the concept of heat energy recovery and reduces the waste of heat energy.

The design and application of economizers greatly improve the thermal efficiency of the boiler and reduce fuel consumption. According to statistics, after using an economizer, the thermal efficiency of the boiler can be increased by 5% to 10%, which is of great significance for energy conservation and emission reduction. In addition, the economizer also has the advantages of simple structure, convenient operation and maintenance, and is in line with the development concept of green and environmental protection.

maintenance

Economizer is a very important energy-saving equipment in industrial production and civil boilers. Its function is to recover the heat in the high-temperature exhaust gas emitted by the boiler, thereby improving the thermal efficiency of the boiler. However, due to long-term use and the influence of the external environment, a layer of impurities and corrosion products will be deposited on the surface of the economizer, which will not only affect the heat transfer effect of the economizer, but also shorten its service life. Therefore, regular cleaning and maintenance of the economizer is particularly important.

First, when cleaning the economizer, you need to use a special cleaning agent. These cleaning agents usually have strong decontamination capabilities and can effectively remove deposits on the economizer surface. During the cleaning process, try to avoid using mechanical force to wipe to avoid damaging the surface of the economizer. In addition, the selection of cleaning agent should also be based on the material of the economizer and the nature of the dirt to ensure cleaning effect and safety.

Secondly, the maintenance of economizer is also crucial. Regularly check the economizer for wear and deformation, and promptly repair or replace damaged parts if problems are found. This is because the economizer works in a high-temperature and high-pressure environment. Long-term operation will cause wear and deformation of its components. If not handled in time, it may cause damage to the economizer and even endanger the safe operation of the equipment.

Finally, reasonable plans and programs should be developed for the maintenance and cleaning of the economizer. Determine the cleaning and maintenance cycle based on the frequency of use and working environment of the economizer. At the same time, the cleaning and maintenance processes are recorded in detail to facilitate analysis and evaluation of the economizer's operating status for better management and maintenance.

In short, the normal operation and service life of the economizer are inseparable from regular cleaning and maintenance. Only by doing this work well can we ensure that the economizer can exert its maximum energy-saving effect, extend its service life, and at the same time ensure the stable operation of industrial production and civil boilers. In the long run, this is of great significance to the realization of my country's energy conservation and emission reduction goals.
