Description and Specification for Lab Tenders
Astra Scientific Steam Turbine Power Plant Setup.
The experimental has been designed specifically for engineering
education in the field of power plant technology, and driving and driven
machines. It offers a wide range of experiments to learn about the
operational processes in a steam power plant.
An oil-fired once-through steam boiler produces wet steam that is turned
into superheated steam by means of a super heater. The boiler’s short
heat-up time means rapid steam generation is possible. Load is applied
to the turbine with a generator. The turbine output is determined by
speed and torque. Downstream of the turbine, the steam is condensed and
returned to the boiler. The feed water circuit is fitted with a complete
water treatment system, which consists of a re generable ion exchanger
and chemical dosing. Sensors record the temperature, pressure, speed,
and flow rate at all relevant points. The measured values can be read on
digital displays. At the same time, the measured values can also be
transmitted directly to a PC via USB. The data acquisition software is
included. The control panel includes a clear process schematic of the
plant. The system is monitored and controlled by a programmable logic
controller (PLC).
The experimental plant is built in accordance with statutory safety
regulations and includes the mandatory safety facilities. The steam
generator is type tested and does not require specific permissions.
The plant can optionally be operated with the cooling tower.
