Teaching suggested applications*

• Study of a steam turbine installation and Rankine cycle, influence of operating parameters on efficiency

• Influence of the use of a superheater upstream of the turbine (superheated or saturated steam)

• Commissioning, adjustments and maintenance

• Electricity production and measurement of all operating parameters (temperature, flow, pressure)

• Cycle plot on Mollier diagram and calculation of thermal power on each element (boiler, superheater, turbine, condenser)

• Study of an open cooling tower and transformation on a psychrometric diagram

• Energy balance and performance of the installation.

• Study of the combustion on the oil burner of the boiler (requires a combustion analyzer not supplied)

• Understanding and identification of specific components for steam networks

• Study and adjustment of a water treatment station by softener and metering pump (injection of anti-oxygen and biocide)

Description

The steam turbine unit consists of a steam boiler, a utility group and a turbine-generator assembly for power generation. The bench is delivered complete, instrumented including safety, control and measurement equipment.

The bench in its general design will comply with the machine directive 2006/42 / EC, pressure equipment PED 97/23 / EC, electrical standard NFC 15100 (other standard on demand).The robust design of this equipment makes it perfectly suitable for use in schools. Its anodized aluminum structure on wheels gives it great strength as well as great flexibility of integration into your premises. The manufacture of this equipment meets the European machine directive.
