SOLAR THERMAL PLANTS

• Y type, basket and self-cleaning strainers for heat thermal fluid.
• Automatic backwash filtres with nitrogen as an alternative for HTF.
• Metal-to-metal triexcentric butterfly valves to isolate thermal fluid.
• Minimum flow valves to protect thermal fluid pumps.
• (For thermal power plants see other applications.)

THERMAL POWER GENERATION
For the principal equipment, see boiler, steam turbine, compressor and condenser applications.

• Gas line filtration. Coalescent filters.
• Filtration in general: basket, Y, duplex, temporary, self-cleaning and cartridge filters.
• Control valves and desuperheaters.
• Pressure reducing and desuperheating stations.
• Gate, globe, check, safety, butterfly and three-way valves.

BOILER
For the boiler feed water line:

• Minimum flow valves for boiler feed water pumps. Pump protection.
• Main boiler feed water control valve.
• Three-way, isolation for economiser/preheater bypass valves.
• Desalination and blowdown.

Boiler:

• Level control: level monitoring/interruption and minimum level safety lines in the boiler drum.
• Desuperheaters: venturi type, fixed orifice, variable multi-nozzle, steam assisted.
• Desalination and blowdown.
• Main steam safety valves.

STEAM TURBINE

• Main steam isolation valve.
• Turbine bypass valves.
• Free flow reverse current valve at cold reheat and extractions.
• Detection and monitoring of the presence of water in condensate wells.
• Atmospheric valves for emergency discharge of condensers.

COMPRESSOR

• Antisurge service control valves to prevent reverse flow.
• Compressor discharge check valve with closure assist air cylinder.
• Fluids handled: cracking gas, ethylene, propylene and other process gases.
