The high-velocity steam impacts the moving blades (rotor blades), pushing the rotor to rotate, thereby converting kinetic energy into mechanical energy. The turbine rotor is connected to drive the generator rotor to rotate for power generation and output.Application FieldsThe basic principle of the extraction back pressure steam turbine is a commonly used cogeneration equipment, and its basic principle is to use fuel combustion to produce high-temperature and high-pressure steam, drive the steam turbine to rotate, thereby generating mechanical work, and at the same time extract part of the steam for heating. The economy of this kind of unit is similar to that of the back-pressure unit, and the economy is better under the design working conditions, but the adaptability to load changes is poor.Power Generation: Thermal systems in high-energy-consuming industrial sectors such as chemical engineering, steel, coking, combined heat and power supply, papermaking, printing and dyeing, sugar refining, metallurgy, and building materials. It replaces desuperheating and pressure-reducing devices for power generation.Industrial Drive: Drives large machinery such as compressors and pumps.Our AdvantagesOur company custom-designs and independently develops high-efficiency condensing steam turbine units, which are multi-stage small enthalpy drop impulse steam turbines. Different from the condensing steam turbine rotors of other manufacturers, the design has 2-4 more pressure stages; the design reduces the distance between flow stages, allowing more stages to be arranged in the flow part. The enthalpy drop of each stage is reduced, the flow diameter is decreased, and the blade height loss is significantly reduced. The flow part of the condensing steam turbine also optimizes the profile design of blades, nozzles, and diaphragm nozzles, effectively reducing all losses in the flow part of the condensing steam turbine, thereby improving the mechanical conversion efficiency of the condensing steam turbine and having a wide load adaptation capacity and overload capacity. This technology was selected into the 2019 China Industrial Energy Conservation Technology and Equipment Recommendation Catalog and Cases issued by the Ministry of Industry and Information Technology of China.Our company's main technical configuration is to optimize the blade profile of conventional units. Through thermal calculation and following the law of "conservation of energy", the design condition parameters of the original unit are matched and optimized with the actual operating conditions. Meanwhile, new partitions are matched. The purpose is to revise the flow area and improve the flow structure, so that the unit can do work effectively and smoothly, thereby achieving the goal of energy saving and efficiency improvement.The high-efficiency labyrinth teeth steam seals independently designed by our company have the following characteristics:1. The labyrinth teeth are lengthened and densified. Based on the original 36 teeth, the density is increased to 45 teeth, and the tooth height is also increased.2. It has better sealing performance. Tests show that under the same steam seal clearance and pressure difference, the densified labyrinth seal reduces leakage losses by approximately 30%-50% compared to conventional labyrinth seals.3. It improves the moisture removal capacity in the blade passages of the wet steam region, reducing water erosion on the last few stages of moving blades.4. It enhances the vibration damping of the shaft, weakens shaft vibrations, and inhibits the formation of steam-induced vibrations.5. It effectively reduces steam leakage, allowing steam to perform work more efficiently, thereby improving the operational efficiency and safety index of the unit.Detailed Photos FAQ1.
