Process unit UV 320

The process unit is based on a gas-fired steam boiler equipped with economizer and super heater. The gas flow os controlled by a pneumatic control valve.
In addition to the steam boiler the process unit also includes water tank with deareator, feed water pump with three phase motor, water cooled heat exchanger, condensate tank and a single phase condensate pump.
The feed water flow is controlled by a pneumatic control valve. The process is equipped with two I/P-converters, one for each control valve.
The process unit is equipped with all necessary armature, saftely valves and a three step load unit relieving steam into the heat exchanger.Normal steam pressure for training in process control is approximately 2.4 bar. Maximum pressure allowed is 8 bar.
The complete process unit is mounted on a square steel tubing stand. The size of the process unit is: Length 320 cm. Width 65 cm. Height 190 cm.
The following flows are supplied with orifice units with complete connections armature for differential pressure transmitters: Gas flow (fuel flow). Steam flow. Feed water flow. The following transmitters are furnished as standard in the process: Smart pressure transmitter for measuring the steam pressure. Smart differential pressure transmitter for measuring the water level in steam drum. Smart differential pressure transmitter for measuring the fuel (gas) flow. Smart differential pressure transmitter for measuring the feed water flow. Smart differential pressure transmitter for measuring the steam flow

Control system UV 720

The DCS system consists of a PC computer with combined operator and engineering station and control unit with I/O hardware. Controller and I/O-units is mounted in a box. The I/O-unit is connected to UV 300 process unit or to the cross connection terminal on one of the other training units.
