The Heat Rate Imperative Today’s business climate creates numerous challenges for power companies. The Clean Air Act and new climate change protocols have put power plants under increased government regulation. The need to comply with these changing standards while also generating sufficient revenue has made heat rate a key performance indicator for all power plants. Before you can correlate any heat rate technology to a return on investment, you must first understand heat rate, its value to your business and the impact that improved heat rate can provide. Improving heat rate 1% can...

Causes of Heat Rate Inefficiency and Fuel Cost Acceleration Most power plants have a life expectancy of 30 - 40 years with many at or reaching their operational longevity. In addition, these plants often use outdated level technologies that cannot achieve a performance level sufficient to manage controllable losses due to instrument-induced errors: • Mechanical or electronic drift due to aging instrumentation, moving parts or intrinsic design. Torque tube/displacer technology requires calibration between shutdowns to achieve reasonable accuracy and prevent nuisance deviation alarms between...

Effectively Measuring and Controlling Heat Rate at Your Facility Reducing heat rate drives overall plant performance – and fuel cost savings. The basic power cycle for a typical steam plant begins at the condenser, where condensed steam from the feedwater heater drains and LP Turbine is routed through each successive stage of feedwater heaters. At the same time, extraction steam from your turbines reaches the appropriate feedwater heaters and the transfer of energy takes place. Maintaining accurate and reliable level controls throughout this cycle is critical to achieve the final feedwater...

Better Feedwater Heater Level Control Generates Greater Benefits Maintaining optimum water level is a critical component of maximizing energy transfer and minimizing controllable losses. Optimizing feedwater heater level control is an effective way to easily improve efficiency (heat rate) and reduce fuel costs. However, a basic familiarity with feedwater operation is critical to understanding how level control can impact your plant. Feedwater heaters use the heat of condensation to preheat water to the correct temperature for the boiler. During this process, shell and tube heat exchangers...
