Metso has already won its 10th repeat order from the Norwegian company Green Energy Group for Neles rotary control valves and triple eccentric disc valves.
The valves were tested in the company’s pilot plant in Kenya, where the valves will control the steamy process flow coming from the boreholes drilled into the ground. The loosened soil from the ground can include silica and sand, which sets special requirements on the valves to be able provide accurate control ability in such rough conditions. One of the challenges in these applications is the silica scaling.
“Not many valves are able to operate in this type of environment,” says Snorri Einarsson, Product Manager, Steam Systems, Green Energy Group.
“We have also benefited from Metso’s Nelprof valve selection program, which saves time since it is easy to use to calculate flow characteristics. The next step will be to get all the plants hooked up to the Metso FieldCare Device and Asset Management software to carry out predictive maintenance with live monitoring of the valve performance,” he continues.
Green Energy Group is famous for building up geothermal power plants quickly due to its unique modular concept. Green Energy Group delivers a unique power plant system that is prefabricated in ready modules and commissioned on-site in weeks. This year Green Energy Group is delivering four geothermal power plants and has received an order for five more plants for next year.
