Their specific applications and advantages in CHP are as follows:1. Core Function in CHP: Cascaded Energy UtilizationBackpressure steam turbines operate by expanding high-pressure (HP) or medium-pressure (MP) steam to a lower "backpressure" (typically atmospheric pressure or a pressure tailored to heating needs). Unlike condensing turbines (which waste residual steam energy as heat in condensers), backpressure turbines recover the exhaust steam for direct use as thermal energy. This cascaded use of energy-first converting part of the steam's energy into mechanical work (to drive a generator or machinery) and then utilizing the remaining heat in the exhaust steam-makes them ideal for CHP systems, where overall energy efficiency can exceed 80% (far higher than the 30-40% efficiency of standalone power generation).2. Key Applications in CHP Systemsa. Industrial CHPProcess Heating: In industries like chemical processing, food & beverage, paper, and textiles, backpressure turbines generate electricity to power plant operations while their exhaust steam (at 5-15 bar, for example) is used for heating reactors, drying, sterilization, or space heating.District Heating for Industrial Zones: Exhaust steam can be routed to heat exchangers to produce hot water, which is then distributed to nearby factories or facilities for heating needs.b. Commercial and Residential District HeatingIn urban CHP plants, backpressure turbines drive generators to supply electricity to the grid or local buildings. The low-pressure exhaust steam (often <5 bar) is condensed in heat exchangers to produce hot water (80-120oC), which is pumped to residential or commercial areas for space heating or domestic hot water.c. Cogeneration with Renewable or Waste HeatWhen paired with biomass boilers, waste-to-energy plants, or solar thermal systems, backpressure turbines enhance the value of these energy sources: high-temperature steam from the boiler drives the turbine for power, and the exhaust steam meets thermal demands, maximizing the use of renewable or waste-derived energy.3. Advantages in CHP SystemsHigh Energy Efficiency: By utilizing both mechanical work and residual heat, backpressure turbines minimize energy waste, making CHP systems far more efficient than separate power and heat generation.Cost Savings: Reduces reliance on purchased electricity and fossil fuels for heating, lowering operational costs for industries or district heating providers.Reduced Emissions: Higher efficiency translates to lower fuel consumption and fewer greenhouse gas emissions, supporting decarbonization goals.Simplicity and Reliability: Backpressure turbines have fewer components than condensing turbines (no condenser or cooling water system), leading to lower maintenance requirements and higher operational availability.4. Considerations for ImplementationHeat-to-Power Ratio Matching: The turbine's backpressure and exhaust steam flow must be carefully matched to the thermal demand of the application. If heat demand fluctuates, supplementary boilers or pressure-reducing valves may be needed to balance the system.Flexibility: While backpressure turbines are less flexible than extraction turbines (which allow partial steam extraction at multiple pressures), they are well-suited for applications with stable, predictable heat loads.In summary, backpressure steam turbines are a cornerstone of efficient CHP systems, enabling industries, cities, and communities to meet both electricity and thermal needs with minimal energy waste-making them a key technology for sustainable energy transition.YTS's Technical AdvantagesSelf-Developed High-Efficiency Steam Turbine UnitBy adopting 2-4 additional pressure stages and advanced blade,nozzle,and baffle nozzle profile designs, our turbine delivers:?
