Improving Turbine Warming System Design for Greater Reliability and Operating Benefits

Turbine Warming Systems (TWS) are an effective means of reducing “Cold” startup times on Combined Cycle Steam Turbines. Reduced startup times result in much shorter “hold” times and allow faster ramp rates for higher MW output. Faster starts result in much shorter times to full load, thus increasing revenue and higher dispatch priority to match the drop off of renewables in the generation stack.

Heater failure in older designs resulted in turbine casing areas receiving little or uneven heat, reducing the efficiency of the TWS and requiring frequent contactor and component replacement.

Older design issues are now resolved by installing redundant heaters and modern controls to extend the heating system life.  With contemporary, engineered designs, significant improvements are made in efficiency, reliability, and longer maintenance intervals.

These improvements can increase the useful life of a TWS to 10 to 15 years.

The TWS eliminates Cold starts, increasing availability and reducing thermal stresses on steam turbine rotors and casings.
