Organic Rankine Cycle Heat Recovery Equipment

Organic Rankine Cycle (ORC) Heat Recovery Equipment covers products that are specifically designed to convert waste heat to electrical power by means of a closed thermodynamic power cycle that does not involve the internal combustion of fuel.

Screw Expanders

Screw expanders are a particular category of saturated steam to electricity conversion equipment. This equipment is designed to convert waste or excess wet or saturated steam, from a specific process, into electrical power. Energy is removed from the steam as the steam expands and pressure reduces across the expander. Such energy is converted into shaft power energy and then to electricity. The technology features a screw rotor which turns as steam passes into the expander reducing the pressure.

Non-condensing or Back Pressure Turbines

Non-condensing or back pressure turbines are a particular category of saturated steam to electricity conversion equipment. This equipment is designed to convert waste or excess wet or saturated steam, from a specific process, into electrical power. Non-condensing or back pressure turbines features rotary turbines where high pressure input steam is allowed to expand as it passes through the turbine. The rotary turbine is connected to the generator through the prime mover, which converts the rotating kinetic energy to electrical energy and generates electricity.
