AFT082 Steam Generator Trainer Teaching Equipment Heat Transfer Demonstrational Equipment
1 Description A steam generator generates steam which will later be used in drives for steam turbines or for heating. Steam generators and steam consumers together form a steam power plant. Steam power plants work according to the Rankine cycle which is still one of the most important industrially used cyclic processes. Steam power plants are mainly used for electrical power generation. The steam generator and the axial steam turbine together form a complete laboratoryscale steam power plant. The trainer serves to familiarise students with the components and principle of operation of a steam generator and enables them to examine the characteristic values of the system. If the steam generator is operated without the steam turbine, the generated steam is directly liquefied in a condenser and fed back into the evaporation circuit via condensate and feed water pump. A water jet pump evacuates air from the condenser and generates negative pressure. The steam boiler is a once-through boiler with small water content and a short heat-up time. As all components are clearly arranged on the front panel, the cyclic process can be easily monitored and understood. Sensors record the temperature, pressure 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 steam generator has been constructed according to the Pressure Equipment Directive, it has been pressure-tested and is equipped with all legally required safety devices. 2 Specification steam generator with gas-powered heater steam turbine can be connected to operate a steam power plant condenser as a thick-walled glass cylinder with water-cooled tube coil and water jet pump for air extraction closed-circuit feed water supply sensor for temperature, pressure, flow rate safety facilities in accordance with the Pressure Equipment Directive for safe operation exhaust gas analysis with exhaust gas analyser software for data acquisition via USB under Windows 8.1, 10 3 Technical data Burner heating power: 6kW Steam generator once-through boiler operating pressure: 8bar, max. pressure: 10bar max. steam temperature: 250°C max. steam output: 8kg/h power of superheater: 750W Measuring ranges temperature: 0…400°C pressure: 0…1,6bar abs.
