Unlike condensing turbines (which exhaust steam at low pressure into a condenser), backpressure turbines discharge steam at a higher pressure, allowing the exhaust steam to be reused for process heating or district heating purposes. This design makes them highly efficient in combined heat and power (CHP) systems.Working PrincipleSteam Inlet: High-pressure steam from a boiler enters the turbine and expands through a series of nozzles and blades, converting thermal energy into mechanical shaft power (used for generating electricity or driving machinery).Exhaust Steam: Instead of releasing low-pressure steam into a condenser, the turbine exhausts steam at a controlled higher pressure (e.g., 0.5-5 bar, depending on the application).Heat Utilization: The high-temperature exhaust steam is directed to industrial processes (e.g., heating, drying, or powering other equipment) or residential/commercial heating systems, maximizing energy efficiency by eliminating "cold source losses" (common in condensing turbines).ApplicationsIndustrial CHP SystemsUsed in factories, refineries, and paper mills to generate electricity while providing steam for processes like distillation, evaporation, or heating.Example: A sugar mill uses backpressure turbines to generate power and supply steam for sugar refining.District HeatingSupplies high-temperature steam or hot water for residential/commercial heating in cities (e.g., Copenhagen's CHP network).Mechanical DriveDirectly powers pumps, compressors, or fans in industrial settings (e.g., in oil and gas plants).AdvantagesHigh Energy Efficiency: No heat loss to a condenser; exhaust steam energy is fully utilized.Lower Capital Cost: Simpler design (no condenser, cooling towers, or related systems).Compact Size: Ideal for space-constrained industrial sites.Customizable Design: Turbine parameters and configurations can be customized according to steam conditions and customer requirements.Reliable for Stable Heat Loads: Performs efficiently when heat demand is consistent (e.g., continuous industrial processes).As a cornerstone of sustainable energy systems, the backpressure steam turbine excels in optimizing power and heat production, making it ideal for district heating, industrial cogeneration, and small-scale renewable energy projects.YTS's Technological Advantages1. Multi-stage Pressure Stages: Its unique multi-stage flow path design significantly enhances unit efficiency. By optimizing the flow structure, the unit can deliver higher power output and achieve greater work output under the same operating conditions, thereby directly generating energy-saving economic benefits.2. Integrally Forged Rotor Assembly Structure: Featuring an integrally forged rigid rotor, the impeller and shaft form an integrated unit. This one-piece design directly improves the rotor's operational safety and stability during operation.3. Reduce the rotor diameter and increase the blade length, compress various contact gaps to reduce steam leakage and make the steam act to the maximum extent, thereby to achieve high efficiency and more electricity generation under the same working conditions.4. Add a sleeve cylinder, usually in casting or forging type, reinforced with a partition sleeve, and works with the newly added pressure stage and partition to increase the working air tightness of the new pressure stage, reduce air leakage and enhance operation safety, thus improve the working capacity of the unit.5. The length and quantity of the comb-teeth steam seal are increased: the number of teeth is raised from the original 36 to 45, and the tooth height is also increased. This improvement effectively reduces steam leakage.6. Comparing with similar steam extraction back pressure units from domestic market, it can improve efficiency by 10% to 30%, reduce the unit dimension and occupy less space at the same time. The optimization of the flow structure enables the unit to produce more power under the same working conditions, thus generate energy-saving economic benefits.Detail Photos Company ProfileAnhui Yuteshuang Energy Conservation Technology Co.,Ltd.(YTS) mainly focuses on thermal systems in large-scale manufacturing and high-energy-consuming industrial fields: Chemical, Steel, Coking, Congeneration(CHP), Papermaking, Printing & Dyeing, Sugar, Metallurgy and Building materials, including but not limited to these indutries.Our main business focuses on producing and optimizing the following equipment:?
