Types of Used Cogeneration Equipment Offered At Industrial Exchange

We offer a broad range of used cogeneration equipment for sale, categorized by functionality. Each category includes detailed information on its operation, benefits, and common applications.

Gas Turbine Generators

Modern Combustion Turbines use high-temperature exhaust gases from a gas turbine to generate electricity. Gas turbines are ideal for industries requiring a high power output with lower operational costs.

Steam Turbine Generators

Often used in industrial processes, steam turbines convert thermal energy from steam into electrical energy. They are typically paired with gas turbine generators and heat recovery systems to increase energy efficiency.

Reciprocating Engines

These internal combustion engines are used in smaller cogeneration systems. They are flexible and can be powered by various fuels, making them a versatile option for smaller facilities.

Heat Recovery Steam Generators (HRSG)

These systems recover heat from exhaust gases and convert it into steam for process use or additional power generation. HRSGs can be customized for different power and heat recovery requirements.

Boilers and Heat Exchangers

Boilers are used to generate steam for cogeneration systems. Boiler fuels can include: Biomass, Natural Gas, #2 & #6 Fuel Oils, as well as Landfill Gas and chemical process waste streams.

How Used Cogeneration Equipment Works

Electricity Generation: Systems generate electricity through combustion turbines, steam turbines, or reciprocating combustion engines.
Heat Recovery: The waste heat from the generation process is captured and used for heating water, steam generation, or direct use in industrial processes.
Efficiency: Cogeneration CHP Systems utilize the same fuel for multiple purposes, thereby reducing energy waste. Thermal efficiencies in a Simple Cycle application range from 20-40%, while CHP systems can achieve total system efficiencies typically ranging from 60% to 80%, sometimes higher.

Cogeneration systems operate by capturing and utilizing radiant waste heat produced during simple cycle electric generation. The radiant heat, which is otherwise lost to the atmosphere, is harnessed for industrial process applications, heating purposes, or additional power generation in a combined heat and power system.

Troubleshooting Tips for Cogeneration Equipment

Decreased Efficiency: If the cogeneration system is operating at lower efficiency, it may be due to issues like fouling of evaporator tubes, feed water treatment, or fuel quality problems. Regular inspection of components can help address this.
Electrical Failures: Inspecting electrical connections and control systems may help identify faults. A Megger test is crucial to determine that your generators and motors are operating properly.
Excessive Vibration or Noise: Unusual vibrations or noises from turbines or engines may indicate misalignment, worn bearings, or a need for lubrication. Regular routine maintenance is necessary to keep the system running smoothly.
Overheating: Inspect the cooling system, including heat exchangers and pumps, to ensure they are functioning correctly. Check for fouling blockages or leaks that could cause the system to overheat.
Fuel Supply Issues: In some cases, fuel-related problems can affect performance. Ensure that fuel lines, filters, and injectors are clean and functioning properly.
