How to reduce the noise of steam boiler.

Noise pollution is one of the three major pollutions in today's society, and steam boilers will inevitably produce noise during operation. Serious noise pollution will do harm to human body, and in severe cases, it will cause headache, upset and even endocrine disorders. So what are the noise reduction measures for steam boilers? However, steam boilers are different from ordinary equipment and cannot be directly sealed and isolated. Steam boilers need combustion and exhaust. Combustion requires mixing oxygen-enriched air. The temperature of flue gas discharged from steam boiler is very high. If isolated in a closed environment, high-temperature gas will damage some components. Therefore, it is not feasible to seal and isolate this road as a whole. The noise components of steam boiler are blower and induced draft fan. Therefore, people invented a method of combining energy saving with environmental protection: building a small soundproof room in the boiler room, equipped with silencing equipment, punching some small holes in the roof and wall of the soundproof room, putting the blower and induced draft fan in the soundproof room, and connecting them with the boiler body through corresponding pipes. Place the blower in the upwind direction of the boiler with the air inlet in the upwind direction. The outside air enters from the air inlet, taking away the heat generated by the components of the sound insulation room, so that these components will not be damaged due to excessive temperature, and these heat will not be lost but will enter the boiler body for reuse. At the same time, the noise removal equipment in the soundproof room plays a role in reducing noise, and the water treatment equipment and management are becoming more and more perfect. With the rapid development of modern industry and agriculture, the environmental quality is deteriorating, and the social requirements for environmental protection are constantly improving. Boiler smoke and dust removal is also from scratch, and the technology of flue gas desulfurization and denitrification is becoming more and more mature. Due to the rapid development of instrument industry and computer technology, the advanced nature and reliability of automatic instruments and components are constantly improved, and the automatic control devices needed for boiler operation are increasingly favored by design managers. In short, in recent years, the development of boilers is very rapid, and the requirements of society are also increasing year by year. Boiler technicians and managers need to master the relevant technologies and knowledge of boilers in an all-round way, and constantly update and enrich them to realize the safe and economic operation of boilers. With the development of steam power, the boiler output and parameters are required to be continuously improved, and the fire tube boiler can not meet this requirement, so the water tube boiler came into being. The steam boiler water tube boiler is characterized in that the tubes of the main heating surface are arranged outside the drum, and the furnace is built with refractory bricks. The burning flame in the furnace washes the outer wall of the tube, and water flows in the tube and naturally circulates between the upper and lower drums. At first, the water tube boiler was a horizontal straight water tube, and both ends of the water tube were connected by a large header. Because of the high strength requirement of the whole square header, the whole header was changed into a diversity box. This ensures the strength, but the header and the handholes on the header are complicated to process and have high precision, and the metal consumption of the steam boiler is also relatively large. In addition, the steam-water mixture in the horizontal water pipe is replaced, and the number of boiler drums is gradually reduced. Water-tube boiler adopts curved water tube as heating surface, which gets rid of the limitation of drum water volume space, greatly increases the freedom of boiler, can completely meet the requirements of increasing capacity and steam parameters of a single boiler, and is easy to flow in layers, which is not conducive to water circulation. Later, the water pipes were arranged vertically, and the square headers were replaced by drum headers and circular headers. Obviously, the smaller the cycle multiple, the more steam is produced.
