In power plants, boilers are important energy conversion equipment, and air preheaters are one of the important components of boilers. However, due to various reasons, air preheaters often have clogging problems, which not only affect the normal operation of the boiler, but also reduce the efficiency of power generation, increase energy consumption and operating costs. Therefore, solving the problem of blockage of the boiler air preheater in the power plant has become one of the key tasks in the maintenance and operation of the power plant.
In order to solve this problem, an in-depth analysis of the causes of the blockage of the air preheater is first required. Common causes of blockage include ash deposition, low-temperature corrosion, steam sootblower failure, and more. These problems are often related to equipment design, mode of operation, fuel quality, and environmental factors. Therefore, for different causes, corresponding measures are taken to prevent and solve the blockage problem.
For serious blockage, mechanical cleaning methods can be used, generally "physical" dredging methods, Anhui Yuanqing Pipeline Technology specializes in the development and production of machines for dredging various heat exchange pipelinesyq-t-3000Industrial Pipe Cleaning Machine。We have 3kw, 55kw high power, can be single-axis, double-axis, and even four-axis work at the same time, improve dredging efficiency, save engineering cycle, the front end of our equipment with cemented carbide steel cutter head, to dredge the dirt on the inner wall of the official road, the size of the cutter head and cleaning brush can be used according to the current working conditions, quickly open up the dirt inside the pipeline, the unique cutter head design, truly achieve 0 damage to the pipe wall, to solve a major problem that the customer's air preheater pipeline is difficult to dredge, When using, it is necessary to choose the appropriate dredging machine according to different types of heat exchange equipment and blockages, and use it according to the operating instructions.
For the problem of low-temperature corrosion, corrosion-resistant materials, increasing the temperature of the inlet air, and reducing the temperature of the acid ** can be used to deal with it. Corrosion-resistant materials can enhance the durability of equipment, increasing the inlet air temperature can reduce condensation, and reducing acid** temperature can be controlled by humidification or dehumidification. These measures can effectively reduce the occurrence of corrosion, thereby extending the service life of the equipment.
In addition to the above measures, power plants also need to establish a sound maintenance and overhaul system, and the air preheater is regularly and thoroughly inspected and cleaned. This includes visual inspection of the equipment, wear detection, blockage cleanup, and more. Through regular maintenance and overhaul, potential problems can be found and solved in time to ensure the stable operation of the equipment.
Solving the problem of blockage of boiler air preheater in power plants requires comprehensive consideration of equipment design, operation mode, fuel quality, and environmental factors. Through the comprehensive application of these measures, the blockage of the boiler air preheater of the power plant can be effectively solved, the power generation efficiency can be improved, the energy consumption and operating costs can be reduced, and the stable operation and sustainable development of the power plant can be provided with a strong guarantee.
