Company: 江苏宇峰装备科技有限公司

Product Description: Steam turbine generator sets in the Jiangsu, Anhui, Zhejiang, and Shandong regions can be considered the core equipment of power plants and thermal power plants. Moreover, steam turbine units are generally large in size and high in power. During operation, the noise generated is also very significant, especially for older units, where the noise impact can extend throughout the entire plant area. So, how can noise control be implemented for steam turbine generator sets? Solutions include using steam turbine enclosures, steam turbine soundproofing (silencing) enclosures, insulation enclosure covers, and steam turbine cosmetic panels. These products are sold to hundreds of power plants and thermal power plants across Jiangsu, Shandong, Zhejiang, and Anhui.I. Issues to Consider in Steam Turbine Noise Control1. Sound Insulation: Select appropriate soundproof panels, soundproof doors, and accessories to ensure the steam turbine soundproof enclosure meets noise control requirements.2. Ventilation: Gas turbines are significant heat sources. When adding a soundproof enclosure, consider installing a ventilation system to expel heat outdoors. The ventilation system must be equipped with electrical control devices to monitor operational status.3. Ventilation Noise: After installing the ventilation system, consider the impact of fan noise on the environment.4. Lighting: To facilitate maintenance personnel in performing routine inspections inside the enclosure, lighting and emergency lighting systems must be installed inside.5. Explosion-Proof: The interior of the steam turbine enclosure, soundproof silencing enclosure, insulation enclosure cover, and steam turbine cosmetic panel soundproof enclosure is classified as Zone 2. Electrical equipment used inside the enclosure and in the ventilation system must have explosion-proof capabilities.6. Disassembly: To facilitate gas turbine maintenance, the soundproof enclosure must be designed for repeated, quick disassembly, ensuring that performance after maintenance is not lower than the original design level.7. Connections: Consider how the soundproof enclosure connects with equipment on both ends and how to minimize connection gaps.8. Structure: Determine the stiffness, strength, and stability of the steel structure of the soundproof enclosure and select suitable section steel.Steam turbine noise primarily consists of aerodynamic noise from the exciter and vibration noise from other components. After years of research and technical development, Jiangsu Yufeng Equipment Technology Co., Ltd. addresses noise control by focusing on the sound source itself, analyzing its characteristics, and designing steam turbine soundproof enclosures based on on-site requirements. They have successfully resolved noise issues for hundreds of power plants.II. Overall Quality Requirements for Steam Turbine Enclosure Projects1. Upon project completion, the overall quality of the steam turbine enclosure, steam turbine soundproof (silencing) enclosure, insulation enclosure cover, and steam turbine cosmetic panel must comply with relevant national, industry, or standard specifications and meet the requirements agreed upon in this agreement.2. When the ambient temperature does not exceed 25°C, the enclosure temperature should not exceed 50°C. When the ambient temperature exceeds 25°C, the difference between the external surface temperature and the ambient temperature should not exceed 25°C.3. Corrosion resistance must comply with the GB2086-2006 standard, ensuring no discoloration or deformation.4. The steam turbine enclosure, steam turbine soundproof (silencing) enclosure, insulation enclosure cover, and steam turbine cosmetic panel must be securely and reliably installed.5. Layout must be reasonable, tight, neat, and aesthetically pleasing.6. Noise must be significantly reduced, with at least a 6 dB reduction after installation.7. Made from cold-rolled steel plates: The enclosure dimensions are 12000mm × 9000mm × 3000mm (customizable). The main columns and beam framework are constructed from rectangular section steel, connected with high-strength bolts, and assembled in a modular structure. The design of the main columns and beam framework must avoid the bearing seats of the steam turbine generator set to prevent interference with bearing maintenance. The four walls are assembled from steel structure soundproof acoustic panels, with the outer layer made of cold-rolled steel plates no less than 1.5mm thick and the inner layer made of 1.0mm thick cold-rolled steel plates.8. The steam turbine enclosure, steam turbine soundproof (silencing) enclosure, insulation enclosure cover, and steam turbine cosmetic panel include 4 soundproof doors with observation windows. The doors must open smoothly and close tightly.9. The lower part of the four walls must have an appropriate number of air inlets (soundproof ventilation openings, with area determined by the bidder).10. The top of the enclosure is made from perforated plates and is equipped with lifting rings for hoisting. Six low-noise fans are installed for forced exhaust and heat dissipation. The interior is equipped with a full set of LED lighting facilities to facilitate inspections by personnel inside the cosmetic panel enclosure.11. The internal space and door positions of the steam turbine enclosure, steam turbine soundproof (silencing) enclosure, insulation enclosure cover, and steam turbine cosmetic panel must be reasonably designed to ensure that cosmetic panel components do not contact the equipment.12. The enclosure must be easy to disassemble and assemble, with reasonably placed lifting rings and holes. The structural strength of individual cosmetic panels must meet requirements for hoisting and stacking without deformation. The needs of major and minor overhauls must be fully considered to minimize disassembly and assembly work during major overhauls.13. The surface paint color of the enclosure is uniform light gray. The surface is treated with electrostatic spraying and high-temperature curing.14. The steam turbine enclosure, steam turbine soundproof (silencing) enclosure, insulation enclosure cover, and steam turbine cosmetic panel must have vibration damping measures at ground contact points to reduce vibration caused by foundation movement.15. The steam turbine enclosure, steam turbine soundproof (silencing) enclosure, insulation enclosure cover, and steam turbine cosmetic panel must be factory-processed and ready for direct on-site installation. On-site fabrication is not allowed, and hot work is prohibited on-site.16. Design, manufacturing, and installation unit: Jiangsu Yufeng Equipment Technology Co., Ltd.■ Excerpted from: Yufeng Equipment     ■ Author: Planning Department    ■ T: 13812456367    Steam Turbine Soundproof Enclosure ManufacturerSteam turbines are the main equipment in power plants and generate high-intensity noise exceeding 120 dB(A) during operation, severely affecting the working environment and endangering human health. Based on noise control practice projects, there are two main technical solutions for addressing steam turbine noise: overall workshop noise reduction and steam turbine soundproof enclosure enclosure. From the perspectives of worker occupational health, environmental noise control costs, and benefits, implementing customized steam turbine soundproof enclosures is currently the most feasible, cost-effective, and efficient method for resolving steam turbine noise issues.Steam turbine noise primarily consists of aerodynamic noise from the exciter and vibration noise from other components. Hanx Soundproofing addresses noise control by focusing on the sound source itself, analyzing its characteristics, and designing steam turbine soundproof enclosures based on on-site requirements. They have successfully resolved noise issues for multiple power plants.Brief advantages of steam turbine soundproof enclosures provided by Lanshide Environmental Protection:1. The design includes composite soundproof panels, soundproof doors, and intake/exhaust silencers to ensure normal operation of the steam turbine without affecting its service life, while facilitating daily maintenance and equipment monitoring.2. The soundproof enclosure is assembled from five side panels into a complete structure, allowing for overall installation and disassembly during major overhauls.3. Based on on-site requirements, the soundproof enclosure for the high-pressure cylinder section can also be designed as a hoistable structure, with the enclosure not fully sealed and featuring ventilation openings and louvers on top.4. Considering safety and aging issues, the inner walls of the panels are coated only with damping paint and an epoxy resin damping layer to reduce panel vibration. more>
