Industrial CHP Systems? Used 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.2. District Heating? Supplies high-temperature steam or hot water for residential/commercial heating in cities (e.g., Copenhagen's CHP network).3. Mechanical Drive? Directly powers pumps, compressors, or fans in industrial settings (e.g., in oil and gas plants) ? Steam 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). High 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.Reliable for Stable Heat Loads: Performs efficiently when heat demand is consistent (e.g., continuous industrial processes).Backpressure steam turbine is a cornerstone of sustainable energy systems, optimizing both power and heat production.YTS's Technical Advantages Self-Developed High-Efficiency Steam Turbine UnitBy adopting 2-4 additional pressure stages and advanced blade,nozzle,and baffle nozzle profile designs, our turbine delivers:?
