With population and urbanisation increasing, along with stringent environmental regulations to reduce CO₂ emissions, the power generation industry is facing pressure to change. Consumers expect power companies to deliver sustainable energy at a low cost while receiving a reliable uninterrupted supply of electricity.
The increasing importance of renewables causes the electricity demand from conventional power plants to be quite variable.
Fossil fuel power plants are more and more called to frequently start-up and shut-down, hence effective operational hours are decreasing, and equipment’s are subject to more stressful conditions.
Power plants must be as productive as possible when called in operation hence reducing downtime due to equipment failures becomes critical.
GESTRA's highly reliable solutions help minimise downtime.
Minimising losses in the steam and water cycle not only enhances flexibility and improves productivity but also positively affects efficiency whilst reducing the CO2 footprint.
For example, zero leakage tight shut-off drain valves help in the speeding up of start-up times by reducing thermal dispersions, as well as zero leakage tight shut-off spray water control valves avoid the risk of thermal shocks in the steam pipe which could lead to unexpected shut-down.
High-pressure applications require safe, robust products that perform well and endure. Phenomena like cavitation, flashing, and high velocity put considerable stress on the valves. Even a limited differential pressure is more than enough to kick-start the internal erosion process in a valve and once erosion has commenced, it will continue until replacement of the trim components – or, most likely, the complete valve – is required.
Replacing valves frequently in your system is time consuming and costly. GESTRA’s wear-resistant severe service ZK valves are designed and manufactured in Germany to meet global safety standards. The result is in an exceptional product that withstands stress and cuts down on maintenance.
The increased number of start-ups requires a strict control of the losses in the steam-water loop.
Minimising high value steam losses such as flash steam to atmosphere will not only reduce water replenishment and relevant treatment costs but will also have a positive impact on CO₂ footprint enhancing plant efficiency.
Zero leakage tight shut-off valves and effective steam traps become a must.

Gas-fired cogeneration power station in Germany replaced turbine drain valves to reduce steam and energy losses.
A Danish power station was looking to reduce leaks and energy losses, but ended up reducing their maintenance too.
Suited to steam-regulated heat exchangers, vacuum systems, drying cylinders, steam driers and systems with very low operating or differential pressures, GESTRA's ball float steam trap remove condensate from steam, cold condensate and distillates.
Safe, reliable and robust control valves for severe service applications - ideal for high differential pressures and critical operating conditions.
Wafer-type non-return (check) valves with spring for installation in any position.
Bimetallic steam traps are highly responsive, very efficient and extremely resistant, making them ideal for superheated and saturated steam systems, along with steam tracing and heating coils.
