High-Efficiency Shell and Tube Heat Exchanger (Evaporator & Condenser)
High-Efficiency Shell and Tube Condenser for Power Generation.The shell and tube condenser, a key component in power plants, adopts a tubular heat exchanger design with vertically arranged tubes to optimize condensation efficiency. Constructed from admiralty brass tubes (70/30 copper-nickel) and a carbon steel shell, it withstands pressures up to 2.5 MPa and temperatures reaching 150°C. The tube bundle features 19mm OD tubes spaced at 25.4mm centers, providing a heat transfer surface area of 500–2000 m². In steam power cycles, it condenses exhaust steam at 50–200 kg/s, reducing turbine backpressure and boosting efficiency by 3–5%. Its vertical layout minimizes floor space while maximizing heat exchange performance for continuous power generation.
Our shell and tube heat exchangers are engineered for critical industrial applications, featuring robust designs and premium materials. The shell and tube evaporator excels in low-temperature environments, equipped with a carbon steel shell and titanium tubes, making it ideal for ammonia-based refrigeration systems. The shell and tube condenser, a key component in power plants, utilizes admiralty brass tubes (70/30 copper-nickel alloy) and a carbon steel shell to optimize condensation efficiency in steam power cycles.
