Faster turbine access by optimised forced cooling

Turbine shut down time can be greatly reduced by optimising the forced cooling procedure.

Detailed analysis can optimise the forced cooling procedure to safely bring the time from 50 to 90 hours down to as little as 20 hours.

We provide each customer with the best solution by:

• thorough review of operating procedures for turbine cooling
• new procedures developed to optimise forced cooling
• comprehensive analysis of the risks and benefits of adopting a change in forced cooling procedures
• ongoing accurate monitoring and control techniques to ensure benefits are realised
• comprehensive analysis of the risks and benefits of adopting a change in forced cooling procedures

Our customers have enjoyed benefits including:

• reduced overall time to cool down the turbine
• earlier access to the turbine for maintenance activities
• increased up-time for generation

Case study Turbine cool down Our customer, a large power station, wanted to shorten the time needed for turbine cooling during maintenance to improve plant availability. It usually takes between 48 to 60 hours to cool a turbine before repairs can begin. HRL Technology developed a method to improve the rate of cooling while maintaining the critical temperature units within the turbine, thereby improving plant availability by 20 hours.  At a rate of AUD$20/MWh, this represents a saving of AUD$220,000 per unit turbine.
