Ringo Válvulas has recently manufactured and supply three complete units of desuperheaters for turbine bypass through Samson Holland to KH Energy for BEC (Biomassa Energie Centrale), a biomass power plant located in The Netherlands.
The steam- water circuit of the biomass power plant have the same requirements as per a conventional or nuclear power plant Steam-water circuit: this includes the requirement of steam cooling and pressure reduction in the turbine bypass line, which is achieved by means of the combination of steam reducing valve, water injection valve and desuperheater units.
Ringo Válvulas developed the complete solution to provide the following benefits:

• A compact and robust design.
• Flanged solution combined with our cage guided control valve, which allows complete and easy maintenance.
• PILOT trim that allows balance plug for high temperature to ensure low thrust that involves a more compact and efficient actuator solution.
• Desuperheater unit with venture design to ensure that velocity of steam is enough to avoid water particles impact in the outlet pipe surface.
