Baker Hughes NovaLT™12 gas turbine—upgrade aged Frame 3 turbine

概述

概述

Technologies, engineering capabilities, and regulatory requirements evolve all the time—and there are many ways to bring the performance of aged turbomachinery more in line with current standards.

Our experienced personnel continually develop and integrate new technologies that increase equipment productivity in the most economical ways. The result is a wide range of conversion, modification and upgrade (CMU) solutions that improve the availability, reliability, emissions, productivity, and lifecycle costs of our customers' installed equipment.

我们已成功在全球范围内执行超过1,500个CMU项目。与客户密切合作,我们的工程师已经开发了优化上游网站的生产的解决方案,生产更多LNG,通过管道运输更多的气体,增加炼油厂和石化植物的产量,更重要。通过简短的回报循环,我们经过验证的CMU解决方案是提高资产价值的最有效方法。

作为原始设备制造商(OEM),我们拥有最佳知识和经验,以评估可应用于您的设备的各种选项的可行性;我们的专业工程团队随时为您提供帮助,确定最佳选择。

Below are just a few examples of the many CMUs we offer.

DLE 1.5 upgrade to reduce emissions for LM2500 and LM2500+ turbines

来自LM2500 + G4发动机的先进燃烧技术(包括升级的设计,材料,涂料和增强的冷却)集成到安装的LM2500基本发动机或LM2500 +涡轮机(SAC和DLE 1.0版本中)。它将25ppm的NOx发射降低至15 ppm,CO2至25ppm-and,并且可以在某些情况下扩展到单位数字排放。汽车绘制也可用于多种发动机型号。

CMU DLE 1.5

PGT25+G4 airfoil upgrade for better performance in hot and cold ambient conditions

Engines are typically designed for best performance at ISO conditions, but many installed units actually operate at hotter or cooler ambient conditions. Changing airfoil profile makes it possible to optimize performance at a specific ambient temperature. Our engineers can study your operating conditions to identify the improvement potential, and then we can redesign and produce low-pressure turbine (LPT) airfoils to obtain new tent curves.

LM2500和LM2500 +热部分维护扩展升级升级

We utilize advanced hot section technology from the LM2500+G4 for an installed LM2500 base engine or LM2500+ (SAC, DLE 1.0 and DLE 1.5 versions). It includes upgraded materials for high stress and temperature resistance, coatings, and enhanced secondary cooling, as well as innovative new digital control features. This solution extends maintenance intervals for the hot section from 25K hours of duty up to 50K hours, reduces operating costs, and increases unit life.

CMU Steam Turbine

High-efficiency stages

我们可以用新设计的刀片更换反应涡轮机的第二级和第3级叶片,具有改进空气动力学。案例研究表明,单桶的效率增加约2%,高于2.3%。

Sealing technology replacement (efficiency and intrinsic safety)

Our latest back-spring seals can be installed with shorter maintenance time, since replacement is done on the blade-carrier with a faster re-assembly procedure. No additional machining is needed, and the rotor and blade-carrier lower half do not need to be removed.

Our abradable seals improve turbine maintainability versus traditional strips seal labyrinth seals, and you can expect 0.4% to 1% lower steam consumption.

COMPORDED到J-STRIPS,我们的刷子密封件减少了平衡或恢复鼓上的泄漏。它们提供1-2分的效率,具体取决于运行条件。

阀门执行器电气化(可靠性,简化和连接)

We provide both electro-hydraulic and electro-hydrostatic valve controls.

The hydraulic option features:

  • Precise position control and fast response time
  • Redundant Linear Variable Differential transformer (LVDT) position sensors
  • High tolerance to contaminants, operates on oil filtered to 24–40 microns
  • 有限的硬件修改和无手动站点校准

静水压选择的优点包括:

  • Simplified package
  • Reduced weight and footprint
  • 即插即用 - 无分隔的现场装配或安装项目

High-efficiency stage technology

Development of the core impeller is the key to improving performance. Our impellers portfolio covers all service requirements, and is continually evolved and updated based on extensive analysis of data from tests and our global installed base. The results are exceptional performance and predictability.

Thermoplastic labyrinth seals to improve efficiency

Common metallic seals are designed with large clearance to avoid contact with rotating elements during operation. Some metallic materials are generally subjected to degradation due to corrosion interaction with gas contaminations, such as chlorides, mercury, and acidic environments.

Our retrofittable labyrinth seal system has reduced clearance thanks to an innovative material that guarantees a better response in case of transient or prolonged contact of the two surfaces. The system can be made from reinforced PEEK, PEK, PAI or VESPEL CR-6120. It delivers a proven polytropic efficiency increase, and is compatible with harsh environments.

Abradable seals

由于与氯化物,汞和酸性环境如腐蚀性污染的腐蚀相互作用,一些金属材料降解。

We therefore offer a teeth-on-rotor (TOR) design with statoric seal in abradable material compatible with extreme ambient conditions. : Al-based METCO601 thick coating is compatible with all environments except mercury, and has no temperature limitations. MICA-filled PTFE (e.g. Fluorosint 500®) is compatible with harsh environments including sour and acid gas, mercury, and chlorides. Our design also minimizes gap leakages, and delivers proven polytropic efficiency increases.

How to get more from reciprocating compressors

高效气缸阀

Our latest cylinder valves have rings shaped to reduce gas pressure losses, and more rings with increased geometric flow area. There are smoother gas passages in the valve seat and guard, lower impact velocities and lower alternate stresses on springs, and new spring caps that avoid contact between spring coils and valve guards. This design enables efficiency up to 40%, 3x longer part life, and improved reliability.
