TTVC コンピューター制御蒸気タービン

The Computer Controlled Steam Turbine, "TTVC", consists of a single stage impulse steam turbine. It includes an injector, a brake, a water cooled condenser, safety mechanisms and all the necessary controls and instrumentation.

The steam passes through two computer controlled and mounted in series solenoid valves before entering the injector.

The steam passes through the injector with an angle of incidence of 20 º towards the blades of the turbine, generating work on them and making the turbine rotate. According to the steam energy, there will be more or less energy in the turbine.

After passing through the turbine, the steam expands and, is collected into the condenser. The steam is condensed by a coil through which cold water circulates.

The turbine is loaded using a brake, which rotates joined to the turbine shaft, to measure the torque. The brake runs against a belt, which is tensioned by a manual screw to vary the torque.

There is a solenoid valve at the outlet of the condenser. When this valve is closed it allows, together with a level sensor, to condense a known volume at a specific time. Thus, the steam flow is determined.

Pressures, temperatures, refrigeration water flow and speed of the turbine shaft are measured using sensors, the force of the brake is measured by a force sensor (load cell) and the steam flow.

The instrumentation allows the torque of the brake to be measured, together with the mechanical power, steam mass flow and steam consumption of the unit.

The unit is equipped with safety devices: a pressure switch and a safety valve for the condenser and PMMA protection screens.

Steam generator is required to work with the TTVC unit. It must have a steam production of 8 Kg/h at minimum pressures of 6 bar. EDIBON can offer its Steam Generator (TGV-6KWA), suitable to work with this unit.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
