STEER (Steam Turbine Efficiency Enhanced Redesign) - A New Patented Design for Steam Turbine Power Plants that Reduces Fossil Fuel Consumption – and Associated Emissions - By More Than 10%.

STEER (Steam Turbine Efficiency Enhanced Redesign) is a new patented design for steam turbine power plants that reduces the fossil fuel consumption – and associated emissions - of an existing plant by more than 10%.
In conventional power plants, the thermal energy required to preheat the boiler feedwater is provided by “extraction steam”, partially spent intermediate pressure steam that is extracted from the turbines and then sparged into the feedwater before it enters the boiler. This system diverts some steam from the turbines and reduces the amount of electricity that is generated by each pound of steam produced.
STEER replaces the steam-driven feedwater preheater with newly developed, state-of-the-art, high efficiency industrial heat pumps (IHPs), enabling the extraction steam to be restored to the turbines to generate more electricity. Source water for the IHPs will be provided through a pumped closed loop heated by a boiler stack economizer. The state-of-the-art IHPs will raise the temperature of the feedwater as high as 300 F while operating with a COP of 6 or 7. This measure alone will reduce the fuel consumption – and associated emissions - of the plant by approximately 7%.
